Kerr 5599 (ABD, BK, BM, K).
Notes:— The two Thai specimens, both collected by Kerr from Doi Chiengdao on the same day in June 1921, were labelled as Ampelocissus barbata (Wall.) Planch. but possess morphological characters atypical of that species. In these specimens the inflorescence is an umbellate cyme and the indumentum lacks the dark erect glandular hairs typically found in A. barbata. The first author noticed that these Thai specimens showed similarities to A. rugosa, but also showed some character differences. According to the original description, A. rugosa has simple broad-cordate leaves often trilobed (Roxburgh & Wallich, 1824), and a recent description by Shetty & Singh (2000) indicates that A. rugosa has simple broad-ovate to suborbicular leaves often shallowly 3–7-lobate. The Thai specimens examined have a cordate leaf-blade with no lobes. In addition, in Shetty & Singh (2000) the A. rugosa description states that the ovary is glabrous, while the Thai specimens have a hairy ovary. No indication regarding the ovary indumentum is given in any of the other descriptions perhaps because it is really difficult to see this character when the flower is wet. The first author believes, however, that given the variability in other species in this genus that this variation is not sufficient to taxonomically separate out Thai material from other A. rugosa. As only two aberrant collections from the same locality were found, additional Thai specimens are required to confirm whether these specimens are A. rugosa or a new taxon. However, at present we treat these specimens as forming the first record of A. rugosa in Thailand.
Wallich’s description (Roxburgh & Wallich, 1824: 480) of Vitis rugosa states that this plant is “A native of all the mountain and other forests in Nipal”, and this corresponds to entry number 5994 in Wallich’s Catalogue of the East India Company Herbarium (Wallich 1828: 205). Although Wallich lists eight collections under Wall. Cat. 5994, only 5994.A is from Nepal (‘Napaliae 1821’)—collected by Wallich himself—and so the lectotype should be chosen from the duplicates distributed under 5994.A. Wallich would have had all the material, later distributed un-mounted under this number, available to him at the time he wrote the species description and so any of the many duplicates (perhaps up to 30) would be suitable for designation as the lectotype. Here we select the specimen in the East India Company Herbarium ‘top set’ as the lectotype (K001122747, K-W) as it is has the best quality of plant material.
In the protologue for Vitis nervosa (Lawson, 1875) only one herbarium collection was mentioned: ‘ Sikkim, Himalaya, alt 4–5000ft., J.D.H[ooker].’. Two specimens matching this description have been found at K, and we have selected as the lectotype the specimen which is a better representative of the species as described by Lawson.
