Description
“Repent or erect, usually branched, short-lived perennials, or rarely annual. Floral parts in 4-7’s; hypanthium not prolonged beyond the 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, strict or branched, densely pubescent, to 1m tall; roots fusiform. Leaves alternate, elliptic to lanceolate, pubescent, to 10 cm long and 2.5 cm wide; sessile. Sepals 4, reflexed, ovate, pubescent, 6.5-9 mm long, 3-4 mm wide; petals 4, 7-15 mm long, 5-12 mm wide; styles 1.5-3 mm long, stylopodium prominent. Capsules cubical, 4-angled, usually narrowly winged, appressed pubescent, 6-10 mm long, 4-5.7 mm broad; bracteoles linear, 2-4 mm long; pedicels to 15 mm long.”[2]
Distribution
L. hirtella ranges from southern New Jersey to the Florida Panhandle, west to eastern Texas, and north to Kentucky, central Tennessee, Arizona, and southeastern Oklahoma.[1]
Ecology
Habitat
This species can be found in wet or dry sandy loam of open areas in wiregrass-longleaf pinewoods, low moist depressions, pine-saw palmetto flatwoods, bogs, floodplain woodland clearings and wet thickets.[3] It has also been observed to occur in human disturbed areas such as along roadsides, edges of pine plantations, ditches, gas pipeline right-of-ways, and power line corridors.[3] Associated species include Ludwigia alternifolia, L. glandulosa, L. linearis, L. pilosa, Pinus palutris, Serenoa repens, Cyrilla, Hypericum, Rhexia, Sabatia, Rhynchospora, Panicum, Macranthera, Bigelowia, Xyris, and Platanthera ciliaris.[3]
Phenology
This species flowers from July through September.[3]
