Achnatherum hymenoides (Roem. & Schult.) Barkworth[FNA24, HC2]
Indian rice grass

Publication: Phytologia 74(1): 7-8. 1993.

Origin: Native

selected vouchers: WTU

Notes: FNA24: "Achnatherum hymenoides grows in dry, well-drained soils, primarily in the western part of the Flora region and northern Mexico. Specimens from further east may be introduced; it is unknown whether they have persisted. The roots of A. hymenoides are often surrounded by a rhizosheath formed by mucilaginous secretions to which soil particles attach. This rhizosheath harbors nitrogen-fixing organisms that probably contribute to the success of the species as a colonizer."
