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 cylindric taproot; stems decumbent to erect, mostly 3-6 dm long, densely pilose or occasionally sparsely appressed pubescent. Leaves 4-12 cm long; leaflets 9-17, oblong-obovate to obovate or elliptic, 1-2.7 (3.7) cm long, 6-14 mm wide, glabrous to finely pilose above, somewhat appressed to spreading short-pubescent to pilose below. Principal inflorescences appearing opposite the leaf or terminal, 4-60 cm long, usually longer than nearest leaf, erect or upwardly curving with a terete or angled peduncle and rachis with persistent, lanceolate to linear bracts; pedicels 1-8 mm long. Calyx 6-7 mm long, sparsely to more typically densely pilose or villous; petals at first white, turning pink then carmine (drying purplish), 1.2-1.7 cm long; stamens diadelphous. Legume 3-5 cm long, 4-6 mm broad, sparsely to moderately pubescent, trichomes more than 0.6 mm long." [1]

Distribution

Ecology

Habitat

Tephrosia spicata can be found in coastal hammocks; wiregrass/pine communities; pine savannas; mixed hardwood forests; longleaf pine-turkey oak hills; turkey oak barrens; and longleaf pine scrub oak sand ridges. [2] [3] It has been found in human disturbed areas such as railroad beds, cut over pine flatwoods, and roadsides. Soil types include loamy sand, sandy loam, clay soil, sand, sandy peat, and sandy clay. [2] Associated species include Phlox floridana, Calamintha dentata, Canna, Sambucus, Aristida stricta, Rhynchospora, Tephrosia floridana and T. chrysophylla. [2]

Phenology

T. spicata has been observed flowering April through October with peak inflorescence in June and fruiting May through October.[2][4]

Seed dispersal

This species is thought to be dispersed by gravity. [5]

Fire ecology

It has been found in recently burned longleaf pine communities. [2]
