Two new species of Curcuma (Zingiberaceae) used as cobra-bite antidotes

Two new species of Curcuma, C. sattayasaii A. Chaveerach & R. 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.

Key words:Curcuma, Curcuma sattayasaii A. Chaveerach R. Sudmoon, Curcuma zedoaroides A. Chaveerach T. Tanee, cobra-bite antidote, new species, Khon Kaen, Thailand.
