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

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

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]
