Taxonomic Notes

Synonyms: P. difforme Le Conte; P. giganteum Baldwin ex Vasey.[2]

Varieties: none.[2]

Description

P. floridanum is a coarse, perennial graminoid of the Poaceae family native to North America.[1] It grows from a stout rhizome. The culms are 5-15 dm tall with glabrous nodes and internodes. The ligules are membranous and 1-2 mm long, while the 2-7 racemes are racemous, ascending, and 3-13 cm long. The spikelets are suborbicular, ellipsoid, 3-4 mm long, and grow in 4 rows.[3]

Distribution

P. floridanum ranges from New Jersey, Illinois, and Kansas, south to Florida and eastern Texas.[2]

Ecology

Habitat

P. floridanum proliferates in wet forests and pine savannas.[4] Specimens have been collected from disturbed roadside in pine-oak woodland, wet pine flatwoods and cypress depression, disturbed sandy field, longleaf pine stand, willow thicket, wiregrass savanna, pond-margin, marsh bank, mesic hammock, hardwood swamp, and sandy loam of hillside seepage.[5]

Phenology

P. floridanum flowers from August through October.[2]

Seed dispersal

This species is thought to be dispersed by gravity.[6]

Conservation and Management

P. floridanum is listed as extirpated by the Pennsylvania Department of Conservation and Natural Resources.[1]
