Studi Floristik Annonaceae di Kabupaten Berau, Kalimantan Timur, Indonesia

Abstract

In the Berau regency, the Annonaceae (excluded thos which are cultivated) is represented by ten different groups (Uvaria-group, Desmos-group, Xylopia-group, Mitrephora-group, Mitrella-group, Miliusa-group, Meiogynegroup, Fissistigma-group, Monocarpia-group, and Mezzettia-group) and consist of 40 species belonging to 21 genera. One species, Artabotrys hexagonolobus will be proposed as new to science. Most of the species grow at low altitude usually well under 1000 m altitude, whereas some Orophea species have been recorded from more than 1000 m altitude. The Annonaceae are used for several purposes, for example: medicine, food, and building material by local people elsewhere. However, the knowledge of this utilization is still very meager locally at Berau and could be better explored for the benefit of the local people.
