Abstract

Burckella coi Fernando (Sapotaceae) is described as a new species and reported as a new genus record for the Philippines and west of the Wallace Line. The genus was previously only known east of the Wallace Line, from Maluku, New Guinea, Fiji, Samoa, and Tonga in the western Pacific. This new species is similar to a small group of species in the genus Burckella Pierre in its growth habit, being a large tree with obovate leaves 10–30 cm long, with many (15–30) secondary nerves and a large number of stamens (25–40). This group includes B. poolei H.J.Lam (Maluku and New Guinea), B. obovata (G.Forst.) Pierre (Maluku to Solomon Islands), B. polymera P.Royen (New Guinea), B. fijiensis (Hemsl.) A.C.Sm. & S.P.Darwin (Fiji), and B. thurstonii H.J.Lam (Fiji). B. coi, however, has 40–50 stamens while there are only 12–16 in B. obovata. Burckella thurstonii is similar to B. coi in having c. 40 or more stamens, but in B. thurstonii the pedicel and calyx are densely pubescent and the fruit are larger (c. 5 cm diameter) compared to B. coi which has a ±glabrescent pedicel and calyx and smaller fruits (c. 3 cm diameter).
