Dwarf upland to alpine perennial. Leaves all radical, pinnate with pinnatisect or pinnatipartite segments. Umbels compound, shortly pedunculate, or sessile and then the rays having the appearance of a number of simple umbels; involucre and involucel conspicuous, of very numerous linear bracts and bracteoles. Flowers hermaphrodite. Calyx-teeth obsolete. Petals small, white to creamy or greenish, glabrous, deeply incised above with an incurved apical lobule. Fruit glabrous, scarcely compressed, oblong-elliptic, the mericarps only slightly narrowed to the commissure; primary ribs slightly prominent, all similar, or the marginal slightly sharper; valleculae each with a single, broad, dark vitta, the commissure bivittate; stylopodia flat or almost so; carpophore fused, the mericarps apparently not separating. Endosperm bluntly pentagonal-subreniform in section.
