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." - Radford et al 1964
"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." - Radford et al 1964
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 (FSU Herbarium; [1]). 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 (FSU Herbarium). Associated species include Phlox floridana, Calamintha dentata, Canna, Sambucus, Aristida stricta, Rhynchospora, Tephrosia floridana and T. chrysophylla (FSU Herbarium).
Phenology
It has been recorded flowering and fruiting May through October (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [1]
Seed bank and germination
Fire ecology
It has been found in recently burned longleaf pine communities (FSU Herbarium).
