San Antonio River Authority

Dichanthelium pedicellatum

Dichanthelium pedicellatum (Vasey) Gould

Cedar Rosette Grass, Corm-based Panicgrass

Poaceae (Grass Family)

Synonym(s): Panicum pedicellatum

USDA Symbol: DIPE4

USDA Native Status: L48 (N)

Low, caespitose grass with often hard, knotty rhizomes and culms that start off erect in spring but become decumbent later. Distinguished by four to seven thin, cauline leaves that are glabrous or sparsely hirsute, widening toward the ends, and lower glumes that do not surround the pedicels.

A grass whose common name derives from its almost exclusive association with Ashe Juniper (Juniperus ashei) and other Juniperus species, Dichanthelium pedicellatum prefers the loose, rich, fast-draining soil produced by fallen juniper leaves and usually occurs on limestone strata in open juniper-oak woodlands and juniper-oak savannahs, ranging from central Texas in the north to Guatemala in the south.
