Description
P. plicatulum is a cespitose, perennial graminoid of the Poaceae family native to North America, Puerto Rico, and the U.S. Virgin Islands.[1] The culms are 4-7 dm tall with glabrous nodes and internodes. The blades are 15 cm long, 1-4 mm wide, usually involute, glabrous on both surfaces, and basally pilose. The sheaths are glabrous, have scarious margins, and 2 mm long ligules. There are 2-3 racemes that are racemose, ascending, and 3-5 cm long. The rachis wing is scaberulous and 1 mm wide. Spikelets are ellipsoid, obtuse, 2.5-2.8 mm long, and grow in 2 rows with 2 abortive rows.[3]
Distribution
P. plicatulum is found along the southeastern coast of the United States from Texas to South Carolina, as well as Puerto Rico and the U.S. Virgin Islands.[1]
Ecology
Habitat
P. plicatulum proliferates in pine savannas and fields.[2] Specimens have been collected from sandhill communities, sand-oak woodlands, pine flatwoods, swamp clearings, full sun woodlands, pine flatwoods, lakeshores, roadside shoulders, savannas, longleaf pine forests, riverbanks, floodplains, wiregrass sandhills, and grassy clearing with loamy sands.[4]
Phenology
P. plicatulum has been observed flowering in May through July.[5]
Fire ecology
P. plicatulum is not fire resistant, but has medium fire tolerance[1]; despite this, populations have been known to persist through repeated annual burning.[6][7]
Herbivory and toxicology
P. plicatulum has high palatability for browsing and grazing animals.[1] This species functions as forage for cattle in the late summer and winter, and is heavily grazed along ditches and wet sites.[8]
