Orchidaceous


a.

Pertaining to, or resembling, a natural order ( Orchidaceæ ) of endogenous plants of which the genus Orchis is the type. They are mostly perennial herbs having the stamens and pistils united in a single column, and normally three petals and three sepals, all adherent to the ovary. The flowers are curiously shaped, often resembling insects, the odd or lower petal (called the lip ) being unlike the others, and sometimes of a strange and unexpected appearance. About one hundred species occur in the United States, but several thousand in the tropics.
