Species Diversity of Gomphandra (Stemonuraceae) in the Philippines.

Gomphandra (Stemonuraceae [Icacinaceae s.l.]) was revised by Sleumer in 1969 prior to its inclusion in volume 7 of Flora Malesiana. At that time, he recognized eight species in the Philippines but wrote that “Specific distinction… is far from satisfactory.” His revision was hampered by a lack of reproductively complete and mature herbarium specimens. Since 1969, approximately 60 collections of Gomphandra have been made in the Philippines. These specimens, combined with uncited older materials and recent field work, suggest that species diversity may be at least twice as great as previously believed. Current comparisons to type images and emended descriptions indicate that many specimens cannot be assigned to previously described species, suggesting there may be eight undescribed and possibly endemic species of Gomphandra in the Philippines. Key distinguishing features include inflorescence structure, fruit shape, and pubescence distribution. However, a final determination of species identity and diversity must await detailed examinations of type specimens.
