Description
P. laeve is a cespitose, perennial graminoid of the Poaceae family that is native to North America.[1] It's culms are 3-7.5 dm tall with glabrous nodes and internodes. Blades are 20 cm long, 1-10 mm wide, and have a papillose-pilose texture. The sheaths are papillose-pilose as well, with ciliate margins and 2 mm long ligules. There are 2-3 racemes are racemose, spreading, 3-7 mm long, 1 mm wide, and have a scaberulous rachis wing. Growing in 2 rows, the spikelets are orbicular and 2.5-3 mm broad with scaberulous pedicels.
Distribution
P. laeve is found throughout the southeastern United States, reaching as far north as New York and Michigan, and as far west as Texas and Kansas.[1]
Ecology
Habitat
This perennial grass is commonly found on forest edges and disturbed areas.[4] Specimens have been collected from habitats that include moist loamy sands at the edges of a pond, grassy slopes of a roadside ditch, open pine/oak flatwoods, coastal hammocks, open swamp margins, dried up pond bottoms, wet sands od a marsh, small swale, wiregrass palmetto flatwoods, cypress pond, low field, and old pasture.[5]
The grass has an intermediate level of shade and drought tolerance.[1]
Phenology
P. laeve flowers from June through August.[6]
Fire ecology
Populations of Paspalum laeve have been known to persist through repeated annual burning.[7]
