early paspalum
Paspalum praecox (commonly known as early paspalum, early crown grass, or Curtis’s crown grass) is a species of perennial grass found in North America.[1] There are two variations: P. praecox Walter var. curtisianum and P. praecox Walter var. praecox.[1]
The stems stand erect, reaching a height between 6 and 9 decimeters (approximately 1.97 to 2.95 feet). P. praecox‘s blades possess a scaberulous margin and may reach up to 20 centimeters in length and 1.5 to 4 millimeters in width (approximately 7.87 by 0.06 to 0.16 inches).[2]
Individuals may have 3 to 5 racemes, each reaching a length between 2 and 6 centimeters (approximately 0.79 to 2.36 inches). Spikelets are obovoid to suborbicular in shape, and are relatively flat. They occur in 4 rows, ranging between 2.2 and 3.2 millimeters in length. The pedicels are 0.1 to 1.1 millimeters in length. When grain is produced it is brown in color, reaching a length of 2 millimeters.[2]
The two variations may be distinguished from one another via the texture of their lower sheaths. The texture of var. curtisianum is hirsute, while var. praecox is glabrous.[1]
Distribution and habitat
[edit]
P. praecox occurs primarily within the southeastern region of the United States, its range stretching from Virginia to Florida and westward to Texas.[3] There is a disjunct population in Illinois.[4] This species can also be found in Cuba.[1]
Throughout its range, P. praecox is considered to be an obligate or facultative wetland hydrophytic species.[5]
This species may be found in habitats such as pine savannas, seepages, swamps, and wet woods.[3][6]
