|Scientific Name:||Curcuma rhabdota|
|Species Authority:||Sirirugsa & M.F.Newman|
|Taxonomic Notes:||This is an easily recognizable taxon without much confusion. But it may hybridize in the wild with other species from Curcuma subgenus Hitcheniopsis when growing sympatrically.|
|Red List Category & Criteria:||Vulnerable B2ab(iii,v) ver 3.1|
|Assessor(s):||Leong-Skornickova, J., Tran, H.D., Newman, M., Lamxay, V. & Bouamanivong, S.|

The area of occupancy for this species is certainly less than 500 km², but it is known from more than five locations (but fewer than ten) and there is continuing decline in the population due to habitat degradation and over-exploitation by flower collectors. From the amounts seen for sale on the markets, it appears that this species is heavily exploited at present, but it is difficult to determine the population reduction. The species is therefore listed as Vulnerable under criterion B2, but further surveys and monitoring is required as this species could well warrant a higher listing.
|Range Description:||So far known from eastern Thailand (close to the Lao border), Cambodia and southern Lao PDR. The extent of occurrence is estimated at 44,557 km² and the area of occupancy is certainly less than 500 km². It is known from more than five locations but fewer than ten.|
