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, cylindric taproot, stems prostrate to erect, to 6 dm long, sparsely to densely, appressed to spreading short-pubescent. Leaves 3-15 (28) cm long; leaflets 7-19, narrowly cuneate-oblong or narrowly to widely elliptic, mostly 1-5 cm long, (2) 5-18 mm wide, glabrous to moderately short-pubescent above and sparsely to moderately short-pubescent beneath. Principal inflorescences opposite the leaves, the smaller often terminal or axillary, 2-23 cm long, often longer than the neighboring leaf, with a conspicuously flattened peduncle and rachis and persistent, oblanceolate to liner bracts subtending pedicels 3-12 mm long. Calyx 3-4.5 mm long, appressed to spreading short-pubescent throughout; petals at first white, turning pink and then carmine (drying purplish), 10-16 mm long; stamens diadelphous. Legume 3-5 cm long, 4-6 mm broad, sparsely to moderately short-pubescent, trichomes 0.5 mm long or less." [1]

Distribution

Ecology

Habitat

Occurs in frequently burned upland pine-grassland communities, pine-palmetto-sand live oak flatwoods, upland turkey oak-longleaf pine woods, Quercus-Serenoa scrub, and pine-oak woods.[2] The communities include soil types ranging from sandy loams to sand (Ultisols, Spodosols, Entisols) (KMR). Human disturbed habitats include roadsides and fields.[2]

Associated genera and species: Galactia, Stylosanthes, Pityopsis, Rhynchosia, Desmodium, Spiranthes praecox, Cassytha, Rhynchosia, Indigofera, Opuntia, dwarf oaks, T. spicata, Alysicarpus ovalifolium , Desmodium lineatum, Lespedeza repens.[2]

Phenology

T. florida has been observed to flower May through October and fruit in May, June, August, October, and November.[2][3]

Seed dispersal

This species is thought to be dispersed by gravity. [4]

Fire ecology

It is a long-lived perennial that readily resprouts following frequent (up to annual) fires.

Conservation and management

T. florida is generally limited to herbaceous communities with limited shade and maintained with frequent fire, suggesting that it is sensitive to fire exclusion.
