This group of genera is separated from the Liliaceae by its extrorse anthers and the septicidal dehiscence of its capsular fruit. It includes bulbous, tuberous, and fibrous-rooted herbs with narrow or broad foliage and showy or inconspicuous flowers. The genera Colckicum and Bulbocodium closely resemble the Crocuses in appearance. Narthecium ossifra-gum, Bog Asphodel, an indigenous bog plant, associated with these plants when they are included as a tribe of the Liliacece, has a loculicidally 3-valved capsule. It has short stiff linear-nerved leaves and bright yellow racemose flowers, appearing in Summer. About 30 genera and 100 species are referred to this order.
