Description
“Repent or erect, usually branched, short-lived perennials, or rarely annual. Floral parts in 4-7’s; hypanthium not prolonged beyond ovary. Capsules longitudinally or poricidally multiseriate, rarely uniseriate. Most of the erect species produce basal offshoots, which have ovate to obovate leaves, in the late summer and fall. Bracteoles occur in pairs on the pedicel or stipe or on the base of the hypanthium.”[2]
"Stems erect, branched, densely pubescent, to 9 m tall. Leaves alternate, elliptic to lanceolate, pubescent, to 7.5 cm long and 13 mm wide; petioles absent or rarely to 2 mm long. Sepals 4, deltoid-ovate, ca. 4 mm long; petals usually absent. Capsules subglobose, pubescent, 3-3.8 mm long and broad; bracteoles linear, 2.5-4.2 mm long; pedicels absent or less than 1 mm long."[2]
Distribution
L. pilosa ranges from southeastern Virginia to north Florida and west to southeastern Texas. It is restricted to the Coastal Plain with disjunct populations in North Carolina, Virginia, and northern Alabama.[1]
