Abstract

Two noteworthy species belongs to the Euphorbiaceae, namely Caperonia palustris and Croton bonplandianus, have been recently collected from Java Island, West Malesia. The discovery of C. palustris is a new record for Malesia region, while C. bonplandianus is considered as a newly recorded alien species to the Flora of Java. Caperonia palustris is characterized by the glandular and non-glandular hairs on its stem and petiole, triangular to lanceolate or subulate stipules, and leaves in ovate-oblong or elliptic-oblong to lanceolate shape. Croton bonplandianus differs from the previously reported species in Java, C. hirtus, by its non-irritating hairs on the stem, sessile basal leaf glands, leaf margin with simple serration, and ellipsoid fruit. Descriptions and a brief discussion are given.
