In botanical terms, monandrous simply means to have a single stamen.

In orchids[edit]

A distinction between monandrous and other flowers is particularly relevant in the classification of orchids. The monandrous orchids form a clade[1] consisting of the subfamilies Orchidoideae, Vanilloideae, and Epidendroideae.[2] The other subfamilies, Apostasioideae and Cypripedioideae, have at least two stamens.

In animals[edit]

In animals, a monandrous system occurs when females have one mate at a time. For example, a female speckled wood butterfly will typically only mate once within her short lifetime.[3]
