Genera

Gymnarrhenoideae is a subfamily within the family Asteraceae, with only one tribe, the Gymnarrheneae. Two very different species have been assigned to it, Gymnarrhena micrantha, a winter annual from the deserts of North-Africa and the Middle-East, and Cavea tanguensis, a perennial herb that grows on scree near streams and glaciers in the Eastern Himalayas. These species have very little in common, other than having two types of flower heads and sharing a tendency towards dioecism.[1][2] Both also have basal leaf rosettes, stretched leaves, with few spaced teeth on the margin, and both lack spines and latex.
