A conspectus of Alangium sect. Alangium (Alangiaceae)

Abstract

ABSTRACT. Alangium sect. Alangium comprises 11 species (and two varieties). The species are primarily defined by their growth habit, viz. erect shrubs or trees versus scandent plants, with additional characters derived from the inflorescences, the size of the flowers, and particulars of the stamens. A key to the species and species descriptions with brief associated information are presented. Alangium amplum W.J.de Wilde & Duyfjes, A. indochinense W.J.de Wilde & Duyfjes, A. melliferum W.J.de Wilde & Duyfjes, and A. sempervirens W.J.de Wilde & Duyfjes are new species; A. frutescens Zoll. & Mor. var. palawanense W.J.de Wilde & Duyfjes is a new variety, and A. longiflorum Merr. var. brachyanthum (Merr.) W.J.de Wilde & Duyfjes a new combination.
