New and Noteworthy Malesian Myrsinaceae, VI. Scherantha, a New Subgenus of Ardisia

Abstract

Eight species originally described in Ardisia Sw., plus a ninth species newly described here, are grouped together to compose a new subgenus, Scherantha, within the genus Ardisia. A key to the species, illustrations, descriptions, and a distribution map of the taxa are provided. The question of generic limits and the characterization of Ardisia, Tapeinosperma, and Discocalyx are addressed.
