Description
X. platylepis is a native perennial forb that is a member of the Xyridaceae family.[1] Leaves are linear, 20-40 cm long and 5-10 mm wide, mostly smooth. Outermost leaves are scale-like, and quickly turn to a dull brown color. Spike is broadly elliptic or oblong, with closely imbricate bracts. Seeds are ellipsoidal approximately 0.5 mm long.[2]
Distribution
The native distribution of X. platylepis consists of the Southeast United States, ranging from eastern Texas to southern Virginia. It has been introduced to Hawaii's main island.[1]
Ecology
Habitat
X. platylepis can be found in savannahs, sandhill seeps, and ditches as human disturbed habitats throughout its distribution.[3] This includes moist to wet sands as well as sandy peats of pineland pond margins, bogs and marshes. [2] X. platylepis has also been observed in a range of habitats including wet loamy sand between pine woods and cypress-gum swamps, moist sand on grassy roadsides, moist sandy loam, wet peat, and sphagnous bog.[4] Preferred habitat for X. platyepis is seepage-fed habitats with herbaceous seepage slopes with mesic or wet flatwoods and prairies or cypress domes that include Sphagnum mosses.[5]
Phenology
Flowering time ranges from August until November in the season.[4]
Fire ecology
Populations of Xyris platylepis have been known to persist through repeated annual burning.[6]
