Didierea

Didierea is a genus of succulent flowering plants in the family Didiereaceae. It is dedicated to naturalist Alfred Grandidier (1836-1921).
Species of "Didierea" are dioecious, with male and female flowers on separate plants. The two known species are endemic to Madagascar, where they are found in the spiny forest–thicket ecosystem. They are listed in CITES appendix II, which means that their trade is restricted to protect natural populations.
