Description

"Perennial herbs and shrubs with either monopodial or sympodial branching. Leaves odd-pinnate; leaflets 7-29 or rarely 1-41, entire, glabrous or pubescent above and always pubescent beneath, usually with prominent, parallel, secondary veins, estipellate, inflorescences terminal, axillary or apparently opposite a leaf, more or less racemose, with 2-10, papilionaceous, pedicellate flowers at each node with the cluster subtended by a bract and each pedicels subtended, 5-lobed, the lowers the long longest; petals clawed; stamens monadelphous or diadelphous. Legume sessile, linear, straight or slightly curved, usually compressed, nonseptate, dehiscing into 2 separate valves." [1]

"Perennial herb from a woody, fusiform taproot; stems decumbent to erct, to 5 dm long, more or less appressed to spreading short-pubescent to short-pilose. Leaves mostly 5-11 cm long; leaflets 9-23, oblong to ovate-lanceolate or narrowly elliptic, 0.7-2.2 cm long, 2-7 mm wide, glabrous to densely short-pubescent above sparsely to densely short-pubescent beneath. Inflorescences opposite the leaves, 5-15 cm long, usually longer than nearest leaf, with a terete or inconspicuously flattened peduncle or rachis and persistent, narrowly lanceolate to linear bracts; pedicels 2-8 mm long. Calyx 3-4 mm long; appressed to spreading short-pubescent; petals at first white, turning pink and then carmine (drying purplish), 1.2-1.5 cm long; stamens diadelphous. Legume 3-4.2 cm long, 4.5-6 cm broad, sparsely to moderately short-pubescent, trichomes 0.6 mm or more long." [1]

Distribution

Ecology

Habitat

In the Coastal Plain in Florida, T. hispidula can be found in recently burned longleaf pine/wiregrass communities; pine flatwoods; sandhills; mixed pine and hardwood swamps; edges of pond cypress wetlands; pine-scrub oak-palmetto woodlands; slash pine-wiregrass woodlands; and along the shore of rivers. [2] [3] [4] In disturbed habitats it has been found along grassy road margins, sand in open woods by a road, sandy peat of a pine flatwoods ditch, and a recently planted slash pine plantation. Substrate types include rich loamy sand, mucky sands, and dry sands. [3] It has been observed to grow with Tephrosia chrysophylla. [3]

Phenology

It has been documented flowering and fruiting May through October. [3]
