The southern African genus Veltheimia (Hyacinthaceae: Scilloideae: Massonieae) comprises the paraptric species pair V. capensis and V. bracteata. Both species are reviewed with full nomenclature, descriptions, ecological notes, and colour illustrations. The two species are distinguished by the shape of the bulb and the texture of the outer tunics, the colour of the foliage, and the flowering time. An epitype is designated to fix the application of the name Aletris capensis in its current sense, and the nomenclature of V. deasii is clarified, including the designation of a lectotype for V. deasii P.E.Barnes, nom. illeg., non V. deasii Coutts. © 2019 SAAB.

1. Introduction Veltheimia Gled. (Hyacinthaceae: Scilloideae) is a genus of two species of horticulturally important geophytes endemic to the western and southeastern seaboard and near-interior of South Africa (Manning et al., 2002). It was established by Gleditsch (1771) for a plant that flowered in the Royal Botanic Garden Berlin in 1766 and 1768 and which he identified as Aletris capensis L. (1759). Gleditsch (1771) characterised his new genus on the basis of its tunicated bulb, nodding, tubular flowers with deflexed stamens inserted near the middle of the tube, and inflated, 3-lobed capsules containing a solitary [sic.] seed per locule. The characteristic fruits, produced by another plant in cultivation at Helmstadt, had earlier prompted Fabricius (1763) to propose the new genus Heisteria but that name is an illegitimate later homonym. Although several species of Kniphofia Moench (Asphodelaceae) were included in Veltheimia by later authors on account of their superficially similar flowers, its circumscription in the current sense had been generally established by the early nineteenth century (e.g. Sweet, 1826). By then it was also recognised that at least two species of Veltheimia were in cultivation in the botanic gardens of Europe (Aiton, 1789; Salisbury, 1796), namely a green-leaved species that had been introduced to Britain in 1768 and which was associated with Aletris capensis L. but later generally known under the name *Correspondence to: Compton Herbarium, South African National Biodiversity Institute, Private Bag X7, Claremont 7735, South Africa E-mail address: [email protected] https://doi.org/10.1016/j.sajb.2019.09.012 0254-6299/© 2019 SAAB.

V. viridifolia Jacq. (1797), and a glaucous-leaved species that had been described as A. glauca Aiton (1789) shortly after its introduction to Britain in 1781 (Sweet, 1826). The application of these names was reviewed by Obermeyer (1961), and her findings have determined the subsequent usage of names for the two taxa (Marais, 1972). Veltheimia is distinguished from other genera in subfamily Scilloideae by its large, tunicated bulbs, several thin-textured leaves with midrib thickened beneath, well-developed floral bracts and associated bracteole, short-pedicelled, tubular flowers with stamens inserted obliquely in a single series near the middle of the tube, and large, nodding, § inflated, 3-winged, papery capsules. The ovary contains 3 or 4 ovules in each locule although mostly just 2 pear-shaped seeds develop per locule (Manning et al., 2004). The nodding fruits are unique in Hyacinthaceae — in other genera with nodding or pendulous flowers the pedicels either straighten after flowering so that the capsules are spreading or suberect (Hyacinthoides Heist. ex P.C. Fabricius, Lachenalia J.Jacq. ex Murray and Ledebouria Roth: Scilloideae) or flex upwards distally so that the fruits are borne erect (Drimia Jacq.: Urgineoideae; Albuca L., Dipcadi Medik. and Ornithogalum L.: Ornithogaloideae). Molecular analyses confirm Veltheimia as a member of tribe Massonieae, where it is retrieved as sister to a clade comprising the € ll.largely southern African winter-rainfall genera Namophila U.Mu € ll.-Doblies, Massonia Thunb. ex Houtt. and Lachenalia, Doblies & D.Mu with an estimated divergence date of § 30 Ma (Buerki et al., 2012). The genus is inferred to be an ancestral tetraploid, with 2n= 40 (Goldblatt et al., 2012) [the report of 2n = 10 in Duncan and Visagie (2009) is a typographical error].

Although both species of Veltheimia have been widely covered in the horticultural literature (Batten, 1986; Duncan, 2004; Duncan and Visagie, 2009), the genus has not been treated formally since Baker (1897) and there are several nomenclatural matters that require resolution, among them the authority for V. deasii. In addition the status of the species will benefit from closer analysis using molecular techniques. It is, therefore, useful to have a complete, modern taxonomic account of the genus available, and this is provided here. 2. Materials and methods All relevant types were examined, as well as all herbarium material from BOL, NBG, PRE and SAM, the primary collections of southern African species, as well as selected specimens from GRA (acronyms after Thiers, 2015). Both species were also studied in the field: V. capensis throughout the western part of its range from Montagu to Hondeklipbaai, and V. bracteata near East London. Specimens are cited according to the Degree Reference System (Leistner and Morris, 1976). 3. Results 3.1. Genus Veltheimia Gled. in Hist. Acad. Roy. Sci. (Berlin) 25: 66 (1771).

Flowering time: mainly May to early Aug. Fig 1. Distribution and ecology: relatively widely distributed through the drier parts of the winter-rainfall West Coast and near-interior of southern African, from Namuskluft and Noordoewer in southern Namibia and the adjacent Richtersveld in Northern Cape, South Africa southwards along the western escarpment of Namaqualand and the BokkeveldHantam, and through the Cederberg and Swartruggens as far south as Darling and the Paardeberg in Western Cape, thence eastwards through the Breede River Valley and the Little Karoo to Albertinia in the south and the Baviaanskloof in Eastern Cape, and inland along the Roggeveld Escarpment and Nuweveld Mts as far east as Murraysburg (Fig 2); on rocky, S-facing slopes and cliffs in succulent karoo, rarely in sand in strandveld thicket or drier fynbos and sandveld shrublands, with the bulbs partially protruding from rock crevices or above the soil, from near sea-level to 1 500 m. Horticultural aspects of the species are discussed by Duncan and Visagie (2009). Diagnosis: distinguished from Veltheimia bracteata by its deciduous habit, ovoid, partly epigeal bulb with the outer tunics persisting in a thick, papery mass, and its glaucous, often more numerous leaves, usually only partly developed at flowering, which is mainly in winter and early spring. The earlier flowering time is important in distinguishing herbarium collections of plants from the east of the range, especially Baviaanskloof, where V. capensis meets the western limit of V. bracteata. Thus Van Jaarsveld 16,096 (NBG) is associated with V. capensis based on its winter flowering as the bulb has not been preserved. Introgression between the two taxa in this region is also a possibility.

Veltheimia capensis is a widespread species that varies in the number, size and shape of the leaves, in the size of the flowers and the level of insertion of the stamens, and in the size of the capsules and seeds. Narrow-attenuate, closely crispulate leaves are characteristic of populations from the drier eastern interior of the range of the species, from Oudtshoorn in the Little Karoo and from the Nuweveld Mtns east to Murraysburg, but also occur scattered through the range of the species. The flowers of V. capensis also vary in the degree of pink speckling, with the northern populations, in Namaqualand and the Richtersveld, consistently among the most darkly coloured in the species, described variously as deep or wine-red, although plants with dark flowers have been recorded elsewhere as well. Application of the name: Gledditsch (1771) associated the name Aletris capensis L. with a plant that flowered in the Royal Botanic Garden in Berlin in 1766 and 1768. The tubular flowers with stamens inserted near the middle of the tube and the inflated, 3-lobed capsules were so different from those of A. farinosa L., the type of the genus, that Gledditsch had no hesitation in describing the new genus Veltheimia for his plant. Unfortunately he does not describe the bulb tunics or the colour of the leaves of his plant and it is therefore not possible to unequivocally identify the species involved. In any event, the name A. capensis was generally applied to the green-leaved plants that were in cultivation in Europe and Great Britain at the time (e.g. Aiton, 1789; Murray, 1770). By then it was clear that the glaucousleaved plants being grown at Kew represented a separate species, for which Aiton (1789) provided the name A. glauca. Both taxa were beautifully illustrated by Jacquin (1797) from plants then in cultivation at the Botanical Gardens in Vienna, the glaucous-leaved one under the name V. glauca and the green-leaved one under the new name V. viridifolia. The inclusion of the earlier name A. capensis as a synonym of V. viridifolia renders the latter an illegitimate superfluous name (Turland et al., 2018: Art 52.1), as was subsequently realised by , 1807). At the time Jacquin (1797) had already Candolle (Redoute clearly identified the salient differences between the two taxa as being the shape of the bulbs, the colour of the foliage, and the flowering time: V. glauca with an oblong-ovoid bulb, glaucous leaves, and flowering in October and November in the Northern Hemisphere; and V. viridifolia with a rounded bulb, bright green foliage, and flowering from December to February in the Northern Hemisphere. It was in this sense that these two names were used by Baker (1870, 1897) in his monographs of the family and also by later authors, until the investigations by John Lewis at the British Museum in response to a request from the South African botanist Amelia Obermeyer, who was preparing the text to accompany a painting of a glaucous-leaved plant that was figured in Flowering Plants of Africa (Obermeyer, 1961). Following their investigations, Lewis and Obermeyer concluded that the name Aletris capensis, contrary to established usage, represented the glaucous-leaved taxon and that the name Veltheimia capensis was therefore the earliest name for the species that had until then been known as V. glauca. Unfortunately Obermeyer (1961) does not give any justification for this decision, merely identifying a specimen in the Linnean herbarium as the type of the name. Her lectotypification (LINN440-2) (Fig 3), has been accepted by Jarvis (2007). The Linnean lectotype of A. capensis comprises just two detached, relatively narrow leaves and an inflorescence. Without the bulb itself, or evidence of the colour of the foliage, it can only be the leaf shape, possibly reinforced by Burman’s (1768) description of the bulb as conical, which informed Obermeyer’s (1961) identification of the specimen in the Linnean herbarium. Certainly either or both species could have been in cultivation in Europe by 1759 when Linnaeus published his name. Obermeyer’s (1961) application of the name was adopted without question (Marais, 1972) and in the interests of nomenclatural stability (Turland et al., 2018: Art 57.1) it seems prudent to designate an epitype to fix the application of the name in this sense. All references to V. capensis in the literature prior to Obermeyer (1961), and

sometimes shortly thereafter (e.g. Moldenke, 1969), thus refer to the green-leaved V. bracteata and not to V. capensis as currently understood. History: the name Aletris capensis was validated by Linnaeus (1759) with the briefest of descriptions mentioning just the nodding flowers [‘floribus nutantibus’], followed by the cryptic reference ‘Burmannus’. I assume this to be a reference to a specimen acquired from Johannes Burman as no species of Aletris is treated in Burman’s (17381739) Rariorum africanarum plantarum. There is, however, a full description of Linnaeus’ Aletris capensis, including mention of the conical bulb [‘Rad. bulbus conicus’], in the later Prodromus florae capensis by the younger Nicolaas Burman (1768: 10). This description, which is far more extensive than others in the work, includes bulb, foliage, flowers and fruits. This is strong evidence that it was based on a living plant, presumably in cultivation at the Hortus Medicus in Amsterdam where both Burman father and son worked. In addition, the types of some of N.L. Burman’s species are thought to be in the Linnean herbarium (Stafleu and Cowan, 1976: 416), and the lectotype in the Linnean herbarium (Fig 3) designated by Obermeyer (1961) is thus possibly a Burman specimen, although it lacks any indication of its origin. Linnaeus (1762) subsequently published a slightly amplified description of his A. capensis that included mention of lanceolate-undulate leaves and an ovate spike, as well as a provenance from the Cape of Good Hope [‘Aletris acaulis, foliis lanceolatis undulatus, spica ovata, floribus nutantibus. Hab ad Cap. b. spei.’]. The additional descriptive information is consistent with the specimen at issue in his herbarium but the locality can only have been supplied to him through conversation or correspondence, once again possibly from one of the Burmans, with whom he was closely acquainted. Veltheimia roodeae was described by Phillips (1924) for a plant collected near Vanrhynsdorp by local resident Mrs R. Rood in June 1923. It was supposed to differ from the known species in its broader, ovate leaves but falls within the variation of V. capensis and was synonymised under V. capensis by Obermeyer (1961). Veltheimia deasii from near Oudshoorn has a more complicated history. The species was based on plants that were collected by Mr

W. Deas in fruit in November 1914 and later in flower in June 1915. These specimens were deposited in the Albany Herbarium in Grahamstown. Additional plants collected by Mr Deas in September 1915 were cultivated at the Bolus Herbarium in Cape Town, where

€ nland, Curator of the they flowered in June 1919. Dr Selmar Scho Albany Museum from 1889 until his retirement in 1927, had intended describing Deas’s plants as a new species but left it to P.E. Barnes (1931), who published it as V. deasii, distinguishing it from V. glauca by its smaller size, more closely undulate or crisped leaves, and the insertion of the stamens below the middle of the perianth. Seeds from the plants in cultivation in Cape Town had, however, in the meantime been distributed from Kirstenbosch Gardens to Kew Gardens in 1921, evidently under the manuscript name. These had reached flowering size by 1926. In an extraordinary coincidence, Mr J. Coutts of Kew published a photograph of a flowering plant and brief description under the name V. deasii in the November 1931 issue of The Gardeners’ Chronicle, a little less than one year before Barnes’s publication, thereby rendering Barne’s name an illegitimate later homonym! In any event, the differences between V. deasii and V. capensis are not significant and it was also correctly included in that species by Obermeyer (1961).

Ovary ellipsoid or fusiform, 1012 £ 24 mm, pale green; style weakly deflexed and recurved apically, 1928 mm long, shortly exserted. Capsules nodding or pendulous, ellipsoidobovoid in outline, 3-winged, 3550 £ 2030 mm, pale-papery. Seeds pearshaped, 56 £ 45 mm, dull black, testa finely wrinkled. Flowering time: mainly mid-Aug to Nov. Fig 4. Distribution and ecology: endemic to coastal Eastern Cape, with a relatively restricted distribution from St Francis Bay in the south to just north of Kei Mouth (Fig 2), typically below 100 m elevation; in coastal bush and scrub on fixed dunes or among rocks, often just above the high-tide level, or shortly inland in riverine thicket or on cliffs. The foliage is often shaded by surrounding vegetation, with the inflorescence protruding into the sunlight. Horticultural aspects of the species, including some named cultivars, are covered by Duncan and Visagie (2009). Diagnosis: distinguished from Veltheimia capensis by its § evergreen habit, subglobose, hypogeal bulb with the outer tunics not persisting, and the glossy pale to deep green foliage, always fully developed at flowering, which is mainly in spring and early summer.

The later flowering time is important in distinguishing herbarium collections of plants from the west of the range, especially Baviaanskloof, where V. bracteata meets the eastern limit of V. capensis. Bract length is variable in both species but plants with large bracts > 20 mm long are only encountered in V. bracteata, the bracts in V. capensis never being more than 20 mm long. Albinoid individuals with uniformly pale greenish or yellowish flowers occur sporadically and have been introduced into cultivation, along with the typical pink or reddish form (Duncan and Visagie, 2009). History: this species has a relatively straightforward history, complicated solely by its confusion with V. capensis, as explained under that species. It was generally known throughout the nineteenth and the first half of the twentieth century under the nomenclaturally illegitimate name V. viridifolia until this was corrected by Marais (1972), at which time the later synonym V. bracteata Baker (1897) was adopted. The latter species was distinguished from V. viridifolia by its longer bracts, as long as the flowers, but this character is variable, even within a single population.

Hybrid taxa Veltheimia £ traubii Moldenke in Pl. Life 25: 44 (1969). Type: Cult. La Jolla, Calif., Traub 1085 (TRA, holo., not located). This taxon was described as the interspecific hybrid V. glauca (Aiton) Jacq. £ V. capensis (L.) DC., and was characterised by precocious flowering as in the pollen parent [‘velut in parenta mascula’] but otherwise

intermediate between the two. The early flowering identifies the pollen parent as V. glauca and suggests that Moldencke was still using the name V. capensis in its old sense as applying to what is currently called V. bracteata. It can be taken therefore to be a true interspecific hybrid following the current taxonomy of the species and not as a direct synonym of V. capensis/glauca.

Without details of the bulb tunics it is impossible to associate it with either of the two recognised species, and the further possibility exists that it may be a hybrid between them.
