Sudmoon and C. zedoaroides A. Chaveerach & T. Tanee with rhizomes traditionally used for many decades as cobra-bite antidotes are described and illustrated. Curcuma sattayasaii is similar to C. longa L., but differs in rhizome horizontally branching on ground; coma bracts pinkish-white or pinkish-pale green; corolla pale yellow with orange tip; labellum pale orange with an orange central band; anther crest very short, broadly ovate, wider than long. Curcuma zedoaroides is similar to C. zedoaria (Christm.) Roscoe, but differs in rhizome branching pattern; the protruding secondary rhizomes curved down; blades oblong to oblong-lanceolate; peduncle glabrous; fertile and coma bracts glabrous; corolla lobes pale yellow to white, lateral lobe ovate, dorsal lobe broadly ovate. The new taxa have been found in a village of Khon Kaen Province, Northeastern Thailand.展开更多
Three new species of Piperaceae, Piper dominantinervium A. Chaveerach & P. Mokkamul, P. pilobracteatum A. Chaveerach & R. Sudmoon from southern Thailand, and P. phuwuaense A. Chaveerach & T. Tanee from nor...Three new species of Piperaceae, Piper dominantinervium A. Chaveerach & P. Mokkamul, P. pilobracteatum A. Chaveerach & R. Sudmoon from southern Thailand, and P. phuwuaense A. Chaveerach & T. Tanee from northeastern Thailand, are described and illustrated. P. phuwuaense is considered rare and endemic to Phu Wua Wildlife Sanctuary. Morphological differences between the new species and related taxa are discussed.展开更多
