Taxonomy
As described in the research literature, is monotypic, including only the species, Zigadenus glaberrimus. Until recently, the genus included a wider range of species, all known as Star Lilies, and it is this gender division is likely to be included in most books and websites.
Before the general reorganization of the plant families that have taken place in recent decades (for example by the APG), Zigadenus was placed in the family Liliaceae.
Description
They are perennials that grow from a bulb or rhizome. In most cases, their narrow leaves grow from the base of the plant. The flowers are bisexual, have six petals are radially symmetrical, and are white or yellowish white in most cases.
They are found in North America, Central America and Asia. The bulbs are toxic to animals and humans, and its intake can cause convulsions, coma and death.
Recent phylogenetic efforts have led to the conclusion that the genre was recognized polyphyletic. The species previously placed in the, have been placed in five genera that are believed to be monophyletic, Amianthium, Anticlea, Stenanthium and Toxicoscordion, leaving only Zigadenus glaberrimus in Zigadenus.
