03FD87DA5868FFADFE17FDC1FDBAFBFC.taxon	discussion	Notes From Fig. 1, it is apparent that the four accessions of W. cauliflora did not form a clade. There are two strongly supported clades of W. cauliflora: one consisting of Winitia cauliflora - 1 and Winitia cauliflora - 2, both cultivated in Bogor Botanical Garden, Indonesia, and another comprising Winitia cauliflora - 3 and Winitia cauliflora - 4, both from Nakhon Si Thammarat Prov., Thailand. The latter clade is the sister group of W. expansa endemic to Phatthalung Prov. of Thailand, though with only weak support. According to van Heusden (1995), the type of Sageraea cauliflora Scheff., which is the basionym of W. cauliflora, was from cultivation in Bogor Botanical Garden, Indonesia (Cult. Hort. Bog. IV-H- 58, origin: Indonesia, Sumatra, Prov. Lampong). The samples Winitia cauliflora - 1 and Winitia cauliflora - 2 were collected from individual X-F- 96 and individual XV-A- 196, respectively, whereas the living individual IV-H- 58 could not be found, probably this individual has died. The morphology of Winitia cauliflora - 1 and Winitia cauliflora - 2 is very much in agreement with that of the type specimens (Scheffer 1881; neotype: L [L 0038174] and possible isoneotype: L [L 0038175]), but is different from that of Winitia cauliflora - 3 and Winitia cauliflora - 4 in several respects, i. e., petal size and shape, and stamen and stigma morphology (Table 1, Fig. 3). On the basis of combined molecular phylogenetic and morphological evidence, Winitia cauliflora - 3 and Winitia cauliflora - 4 should be classified in a species distinct from W. cauliflora. The name Stelechocarpus longipes Craib (Craib 1923) is available and its type specimens, which were also collected in Nakhon Si Thammarat Prov., Thailand (holotype: http: // specimens. kew. org / herbarium / K 000382080), is morphologically similar to Winitia cauliflora - 3 and Winitia cauliflora - 4 regarding leaves, inflorescences, and flowers. Therefore, a new combination in Winitia for Stelechocarpus longipes is made. It should be noted that although the name Stelechocarpus nitidus King (King 1892) is older, its type specimens collected from Perak, Malay Peninsula (lectotype: http: // specimens. kew. org / herbarium / K 000382081) exhibit petals that are similar in size and shape to those of Winitia cauliflora - 1 and Winitia cauliflora - 2 (Table 1, Fig. 3 A); hence, for now we still consider it as a junior synonym of W. cauliflora until more evidence is obtained. On the basis of personal observations by the second author, W. longipes is generally found near streams. During monsoon seasons, the areas where this species occurs are shortly flooded, and it is possible that the ripe monocarps fallen on the ground are taken away by the water current. Sometimes the seeds are found germinated despite still being partially covered by the pericarp. Winitia longipes is widespread in Nakhon Si Thammarat and neighboring provinces where several protected areas are located, but many individuals do occur outside the protected areas; these unprotected forests diminish nearly every single day due mainly to agricultural expansion (pers. obs.). Therefore, we recommend that its conservation status based on IUCN (2012) be assessed as “ Near Threatened (NT) ”. The phylogenetic results (Fig. 1) revealed that Winitia aff. expansa - 1 and Winitia aff. expansa - 2 formed a strongly supported clade, which is not the sister group of W. expansa. Although W. expansa as well as Winitia aff. expansa - 1 and Winitia aff. expansa - 2 exhibit inner petals that are spreading at anthesis (Fig. 4 A – B), the latter two accessions differ from W. expansa by having a non-glaucous appearance on the petal adaxial surface (Fig. 4 A – B; glaucous in W. expansa; Chaowasku et al. 2013) and shallow pits on the adaxial surface of the inner petals (Fig. 4 B; no pitted structures in W. expansa; Chaowasku et al. 2013). In addition, the inflorescences of Winitia aff. expansa - 1 and Winitia aff. expansa - 2 are mostly clustered on large roots and at the unswollen base of trunks, while those of W. expansa are mostly clustered at the swollen base of trunks. Based on the above-mentioned differences, Winitia aff. expansa is described as new to science.	en	Chaowasku, Tanawat, Aongyong, Kithisak, Damthongdee, Anissara, Jongsook, Hathaichanok, Johnson, David M.

03FD87DA586AFFA1FE62FB7FFAE9FDC6.taxon	diagnosis	Diagnosis Morphologically similar to Winitia expansa, differs by having a non-glaucous appearance on the petal adaxial surface (glaucous in W. expansa) and shallow pits on the adaxial surface of the inner petals (no pitted structures in W. expansa). Moreover, its inflorescences are mostly clustered on large roots and at the unswollen base of trunks, whereas the inflorescences of W. expansa are mostly clustered at the swollen base of trunks.	en	Chaowasku, Tanawat, Aongyong, Kithisak, Damthongdee, Anissara, Jongsook, Hathaichanok, Johnson, David M.

03FD87DA586AFFA1FE62FB7FFAE9FDC6.taxon	biology_ecology	Field notes Flowers orange-pink. Notes The new species is so far known only from Phanom District. We observed only three individuals, which occur among limestone outcrops beside a trail surrounded by a rubber tree plantation. In Khlong Phanom National Park where this species has also been reported (Gardner et al. 2015) less than ten individuals were found (pers. comm., S. Gardner). Based on our observations and estimations, we believe at least the category “ endangered: EN D ” (IUCN 2012) is applicable.	en	Chaowasku, Tanawat, Aongyong, Kithisak, Damthongdee, Anissara, Jongsook, Hathaichanok, Johnson, David M.
