L. Merremia cissoides (Lam.) Hallier f., Bot. Jahrb. Syst. 16: 552. 1893.
This is the first record of this weedy tropical American species in Thailand. It will likely increase its range as it has done elsewhere in the Old World tropics.
Thailand.— SOUTHEASTERN: Sa Kaeo [Muang distr., Pang Sida National Park, beside park headquarters building, 220 m, 11 Jan. 2002, Jaikrasane 173 (CMU), Pang Sida National Park, 600 m, 31 Jan. 2003, Jaikrasane 252 (BCU)].
M. Merremia poranoides (C.B.Clarke) Hallier f., Bull. Herb. Boiss. 5: 375. 1897; Staples, Edinb. J. Bot. 61: 91–92. 2006.
This is the first report of M. poranoides in Thailand. Staples (2006) documented the species occurrence in India, China, and Vietnam but no Thai collections had been seen up to that time.A single rather scrappy collection has since some to light. The sessile, foliaceous bract at the peduncle apex is distinctive.
Thailand.—NORTHERN: Chiang Mai [Om Koi distr., on the Bo Luang tableland, Mae Tuen Watershed Improvement Station to Nang Kruan waterfall, 950–1100 m, 18 Oct. 1979, T. Shimizu et al. T-19201 (BKF)].
Paweena Traiperm is grateful to Dr. Chumpol Khunwasi and Dr. Busban Na Songkhla (BCU) for their help and guidance in her studies for the M.Sc. Both authors wish to thank Tanucha Boonjaras for illustrating Argyreia leucantha and permitting us to reproduce the figure here. The insets showing the hairs (Figure 4) were prepared by Miss Panjaree Inthachub (BKF). The first author wishes to thank the directors and staff of all herbaria cited in the text for loans and access to collections in person. In particular, typifying Argyreia splendens required specialized assistance: Tim Harris (K) expertly prepared digital images of Wallich Herbarium specimens and Dr. N. Hind (K) offered guidance on which handwriting might be Roxburgh’s; Olof Ryding (C) searched for authentic Hornemann Herbarium specimens that could be original material; John McNeill (E) offered nomenclatural advice on choosing a neotype. Drs Marc Pignal and Thierry Deroin (both P) provided digital photos for numerous Indochinese types. Dr Kongkanda Chayamarit provided funding and coordination during several visits and the BKF staff offered much herbarium assistance, as did the staff of BCU, BK, CMU, KKU, PSU, and QBG. A Singapore Botanic Garden Research Fellowship in 2006 made possible detailed comparison of Malaysian specimens with a number of recalcitrant collections from peninsular Thailand. This material is based upon work supported by the US National Science Foundation under grant 0212762.
