Description
Panicum gymnocarpon may reach a height of up to 1 m (3.3 ft). Culms range in length from 60 to 130 cm (2.0 to 4.3 ft). Its leaves are linear in shape and alternately arranged, reaching a length of 15 to 40 cm (6 to 16 in).[3][4]
When inflorescence occurs, panicles reach a length between 10 to 40 cm (4 to 16 in). Spikelets are glabrous and narrowly lanceoloid in shape, ranging in length from 5.5 to 7 mm (0.22 to 0.28 in).[4] Blooms range from brown to green in color and occur from July to October.[5]
Distribution and habitat
Within North America, P. gymnocarpon is found primarily within the southeastern region of the United States.[2] Its range extends from Virginia to Florida and westward to Texas and Oklahoma.[6]
It is considered to be an obligate wetland species across its range.[6] It can be found in habitat types such as swamps, environments with seasonally flooded soils, stream and lake banks, and wet woodlands.[7][4]
