Sporobolus compositus (Poir.) Merr. var. compositus[FNA25, HC2]
rough dropseed

Publication: Circ. Div. Agrostol. U.S.D.A. 35: 6. 1901.

Origin: Native

selected vouchers: WTU

Notes: FNA25: "Sporobolus compositus grows along roadsides and railroad right of ways, on beaches, and in cedar glades, pine woods, live oak-pine forests, prairies, and other partially disturbed, semi-open sites at 0-1600 m. Its range lies entirely within the Flora region.

The Sporobolus compositus complex is a difficult assemblage of forms, perhaps affected by their primarily autogamous breeding system (Riggins 1977). Asexual proliferation via rhizomes adds to the species ability to maintain local population structure and to perpetuate unique character combinations.
