Revision of Schradera (Rubiaceae-Schradereae) in Malesia

Abstract

A taxonomic revision of the Asiatic taxa of Schradera Vahl (formerly known as Lucinaea DC.) is presented. 16 species are recognized. Two new species (S. grandiflora, S. pseudonervulosa) are described from Borneo. The new name S. elmeri is published for the Philippine endemic previously known as Lucinaea involucrata. Two new subspecies are recognized in S. korthalsiana (subsp. korthalsiana and subsp. robusta) and three in S. membranacea (subsp. membranacea, subsp. flagellarioides, and subsp. parvifolia comb. & stat. nov.).
