Flora Malesiana Bulletin No. 1 was issued in 150 copies, 112 of which were distributed to cooperating institutes, libraries, botanists and besides, to interested persons. A cardboard holder will be forwarded to libraries through the care of Dr Fr. Verdoorn, Waltham, Mass., U.S.A. In this number two new headings are found viz the first of a series of contributions regarding the dates of publication of certain botanical works of major interest to Malaysian botany, and a first contribution towards an annotated list of little-known publications which appeared during World War II.
