Part of the The Families and Genera of Vascular Plants book series (FAMILIES GENERA, volume 3)


Perennial herbs from tunicated, bulb-shaped corms with basal innovation; aerial stem erect, leafy; leaves alternate, flat and linear, sheathing at the base, cylindrical-subulate at the apex. Inflorescence thyrses or pseudo-umbellas, many-to few-flowered. Pedicels often provided with a lateral prophyll. Flowers not articulated, hermaphrodite, actinomorphic, trimerous and epigynous; tepals 3 + 3, free nearly to the base, blue, violet or white, the outer ending in a prominent point emerging slightly below and outside the apex; stamens 3 + 3, inserted at the base of the tepals; anthers basifixed, tetrasporangiate, introrse-latrorse and longitudinally dehiscent; style erect, slender, apically tribrachiate, with dry stigmatic surfaces; ovary inferior, trilocular, with numerous ovules in axile placentation; ovules anatropous, crassinucellate; capsule loculicidal, dehiscent at the top; seeds numerous, ovate to pear-shaped, reticulate, testa black, phytomelanous, albuminous, the endosperm starch-free; embryo straight, fusiform, nearly as long as the endosperm.
