Geosiris aphylla

Geosiris aphylla is a species in the flowering plant family Iridaceae, first described in 1894. It is endemic to Madagascar.[1]

Geosiris aphylla is sometimes called the earth-iris. It is a small myco-heterotroph lacking chlorophyll and obtaining its nutrients from fungi in the soil.[2]

Description[edit]

Its rhizomes are slender and scaly, and stems are simple or branched. The leaves are alternate, but having no use, are reduced and scale-like (hence the epithet "aphylla," meaning "without leaves"). The flowers are light purple.

Range and habitat[edit]

Geosiris aphylla is native to central and eastern Madagascar. It lives in forest humus in humid lowland and montane forests, between 400 and 1200 meters elevation.[3]
