1E1287B5FF97FFCAFF37FF29FF46F87C.taxon	discussion	Notes: — Polyalthia heliopetala is contrasted with P. oblonga and P. motleyana in Table 1. Turner (2014) accepted P. oblonga and P. motleyana as distinct species, but his description of P. oblonga differs sufficiently from King’s protologue that data are given separately from the two sources. For P. motleyana the description of Turner (2014) alone was used for comparison. A distinctive feature of the petals of P. heliopetala that has not been described for either of the other two species is the raised and thickened patch of tissue at the base of both the outer and the inner petals (Figs. 1 D, 2 C).	en	Bunchalee, Pasakorn, Leeratiwong, Charan, Johnson, David M.

1E1287B5FF92FFCCFF37FCF1FAE6FCB2.taxon	diagnosis	Polyalthia taweensis resembles P. obliqua Hook. f. & Thomson (1855: 138) in leaf shape and size and the shape of the petals, but differs in having supra-axillary or leaf-opposed inflorescences, greenish yellow petals, a differentiated border along the margin on the inner surface of the outer petals, sepals 4.0 ‒ 5.0 mm long, and one pedicellar bract. In contrast, P. obliqua has axillary inflorescences on leafy or leafless branches, white petals, the inner with a rosy flush at the base (Sinclair 1955), the inner surface of the outer petals uniform in texture, sepals ca. 2.0 mm long, and two pedicellar bracts, one attached at the pedicel base and the other at the pedicel midpoint.	en	Bunchalee, Pasakorn, Leeratiwong, Charan, Johnson, David M.

1E1287B5FF92FFCCFF37FCF1FAE6FCB2.taxon	discussion	Notes: — Comparative data on P. obliqua used in the diagnosis were taken from Sinclair (1955). Inflorescence position in Annonaceae is usually a conservative feature indicating distinction at the generic level or a marker for groups of related species within a genus, so it is surprising to have this distinction between two otherwise similar species. Turner (2008) documented the same difference, however, between Polyalthia subcordata (Blume) Blume (1830: 71) and Polyalthia elliptica (Blume) Blume (1830: 73), so inflorescence position appears to be a more variable character within Polyalthia than in other Annonaceae genera. The differentiated border of the outer petals in P. taweensis is an unusual feature; in other Annonaceae such modifications occur only on the inner petals (van Heusden 1992).	en	Bunchalee, Pasakorn, Leeratiwong, Charan, Johnson, David M.

1E1287B5FF91FFC2FF37FC4FFDA1F8AF.taxon	discussion	Notes: — This is the first report of Polyalthia pumila for Thailand. The species is notable for its stature, among the shortest in the family (Sinclair 1955). It is similar to P. motleyana and its relatives in having branches with distichous phyllotaxis, a lamina with a more or less bullate surface, the leaf base more or less cordate, and secondary veins with simple brochidodromous venation.	en	Bunchalee, Pasakorn, Leeratiwong, Charan, Johnson, David M.
