Dioscorea laurifolia Wall. ex Hook.f., Fl. Brit. View in CoL India 6: 293.1892.
Lectotype (designated here): Penang, fl., s.d., G. Porter s.n. (BM [BM001049925 digital image!]; isolecto K [K001104831, K000098237, K000098238 digital images!], CAL [Acc. No. 477394!]). Fig. 4 View Fig
Notes: Hooker (1892) validated D. laurifolia Wall. (Numer. List No. 5111, nom. nud.) and mentioned three collectors, viz. Porter, Maingay and Hullet in the protologue. Four sheets from Penang, Porter (Wall., Numer. List No. 5111) has been located, one at BM (BM001049925) and three at K (K001104831, K000098237, K000098238) and all can be regarded as syntypes (Art. 9.4, 9.6; Turland et al., 2018). Also, no collection under Maingay and Hullet is traceable in any of the herbaria. Furthermore, in synonymy, a collection from Penang by Porter is referred under D. glabra (Wall., Numer. List No. 5105B). Three sheets have been traced under the name at BM and K (BM001049881, K001104787, K001104788), but we could not recognize any elongated unilaterally panicled male spikes in the specimens which is one of the key characters of D. laurifolia . Hence, these are not considered under D. laurifolia here. Among the four recognized sheets, the specimen (BM001049925, https://data.nhm.ac.uk/dataset/ collection-specimens/resource/05ff2255-c38a- 40c9-b657-4ccb55ab2feb/record/4544812) with Porter’s annotation best agrees with the protologue and is designated here as the lectotype and others consequently as isolectotypes.
