Taxonomy of Alangium section Conostigma (Alangiaceae)
Alangium Lam. sect. Conostigma Bloemb. is largely confined to the Malesian area and contains 19 species. By using the characters as found in the original species-descriptions, and with emphasizing the nature of the indument of the leaf bud, the confusingly variable Alangium javanicum s.l.-complex could be dismantled for a great part. Four new species: A. ledermannii, A. pallens, A. plumbeum, and A. subcordatum, and two new varieties: A. meyeri var. macilentum and A. ebenaceum var. insignis are recognised. Two taxa are raised to specific status: A. nobile subsp. denudatum to A. denudatum and A. javanicum var. minahassicum to A. minahassicum. A key to the species is presented, and the concerned taxa are enumerated, referenced, described and some are figured.

An international electronic-only journal on the biodiversity, evolution and biogeography of plants (systematics,
floristics, phylogeny, morphology, anatomy). For floristic studies, the focus is on tropical Africa south of the
Sahara; tropical Southeast Asia with a strong emphasis on Malesia; South America with emphasis on the
Guianas. The language is English.
