Flowers: sepals 3, distinct; petals 5-7; stamens 6-15; pistil 3-4-carpellate; ovary ovoid, 1-locular; style absent; stigmas 3 (-4), linear, radiate-recurved, appressed or adherent to ovary.

w United States

Discussion

Species 2 (2 in the flora).

These diminutive (but handsome) desert endemics are among the smallest plants in the family. Little is known about their life histories, reproduction, ecological interactions, or evolutionary histories, and they merit more field and laboratory study.
