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.
