Streptochaeta Explained

Streptochaeta is a genus of plants in the grass family. It is the only genus in the tribe Streptochaeteae of the family Poaceae.^{[1] [2] [3]}

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.^[4]

Species

Species include:

• Streptochaeta angustifolia Soderstr. — endemic to Espírito Santo state of southeastern Brazil, not seen in wild since 1972 and possibly an extinct species.
• Streptochaeta sodiroana Hack. — Chiapas and Tabasco states of southern Mexico; all Central American countries except El Salvador; Ecuador; Peru; and Venezuela.
• Streptochaeta spicata Schrad. ex Nees in C.F.P.von Martius — widespread from Veracruz (México), the Caribbean to Trinidad island, and South America to Paraguay.
