Whether it is autochthonously specialized or actually related to, and derived from, some Old World ancestors, such as the Central Asiatic-Near Eastern Cleome sect. Thylacophora Franch, the dozen or so species of which, probably through convergence, also bear epipetaloid glands, remains to be determined.</p> |tables= |references= }}<!-- --><!-- -->{{#Taxon: name=Carsonia |author=Gordon C.
