Abstract

Two new species, Sonerila cornuta and S. phaluongensis, discovered in Vietnam, are described and illustrated. The first, superficially similar to S. reptans, however, it is distinguished by an obclavate hypanthium (vs. cylindrical-campanulate or obconical) and purple anthers (vs. yellow), with the base having two prominent S-curved lobes (vs. lobes at the base of anther short, inconspicuous). The second, is morphologically similar to Sonerila betongensis but differs in having a quadrangular, 4-winged stem (vs. terete), glabrous leaves (vs. densely hispid), shortly cylindrical hypanthium (vs. cupuliform to campanulate) that is sparsely covered with glandular hispid hairs (vs. relatively densely hispid with simple hairs), and the anther base with two prominent lobes (vs. small, inconspicuous). In addition to the formal description, line drawings, color plates, information on distribution, ecology, and conservation status, as well as comparisons with morphologically similar species, are provided for each species.
