Conservation Actions [top]

Conservation Actions:	Listed on CITES App. II, but enforcement of the laws in the countries of destination is needed. The plants are widely available throughout the world as a result of propagation from illegally exported specimens propagated from the original collection with approval of low level Mexican government officials. At this time, conservation measures would be counterproductive if they involved the type locality.
