Bifora(redirected from Pifara)
a genus of umbelliferous plants. They are annual grasses with unsegmented leaves. The flowers are small and white, arranged in complex umbellae. The fruit divides into two almost spherical hemicarps. There are three species in the temperate and warm regions of the Old World and one in North America. There are two species in the USSR: B. radians, found in the southwestern European part, in the Crimea, and in the Caucasus; and B. testiculata, found in the Caucasus and occasionally in Middle Asia. Both species are short, branching plants that grow in fields, gardens, and vineyards. They are used by local people as a spicy seasoning in food.
