Streptochaeta

Streptochaeta is a genus of plants in the grass family. It is the only genus in the tribe Streptochaeteae of the family Poaceae.

The species of Streptochaeta are native to neotropical realm regions of North America, the Caribbean, Central America, and South America.

As the genus is an early-diverging sister lineage in relation to most other grasses, the genome of S. angustifolia has been sequenced to study the evolution of the Poaceae.
