Description
Perennial herbs, stems woody below, or from woody crown or caudex. Taproot present. Nodules present. Stems prostrate, trailing, or mat forming, less than 1 m tall. Stems solid, sparsely to densely hairy, stem hairs hispid to villous. Stipules inconspicuous, absent, or caducous; setiform, subulate or acicular; persistent, free. Leaves alternate, petiolate, compound, odd pinnate, leaf or leaflet margins entire, opposite, 5-9 in number, hairy on one or both surfaces. Inflorescences are racemes, terminal, leaf-opposed. Bracts conspicuously present. Flowers zygomorphic. Calyx 5-lobed, hairy. Petals separate, clawed, color white, pinkish to rose, blue, lavender to purple, or violet, though typically white in the sandhills of northern Florida, bicolored or with red, purple or yellow streaks or spots, typically pink stripes in the sandhills of northern Florida. Banner petal ovoid or obovate, petal suborbicular, broadly rounded. Wing petals narrow, oblanceolate to oblong, auriculate. Wing tips obtuse or rounded. Keel petals auriculate, spurred, or gibbous. Keel tips obtuse or rounded, not beaked. Stamens 9-10, diadelphous, 9 united, 1 free. Filaments glabrous. Style terete, sharply bent, hairy on one side only. Fruit a legume, unilocular, freely dehiscent, elongate, straight, exserted from calyx. Valves twisting or coiling after dehiscence. Fruit beaked, hairy, 3-10 seeded. Seeds ovoid to rounded in outline, surface smooth, color olive, brown, or black, surface mottled or patchy.[2]
The root system of Tephrosia chrysophylla includes stem tubers which store non-structural carbohydrates (NSC) important for both resprouting following fire and persisting during long periods of fire exclusion.[3] Diaz-Toribio and Putz (2021) recorded this species to have an NSC concentration of 257.9 mg/g (ranking 16 out of 100 species studied) and water content of 22.8 % (ranking 16 out of 100 species studied).[3]
According to Diaz-Torbio and Putz (2021), Te[hrosia chrysophylla has stem tubers with a below-ground to above-ground biomass ratio of 0.77 and nonstructural carbohydrate concentration of 257.9 mg g-1.[4]
Distribution
Tephrosia chrysophylla is found in the Florida, Georgia, Alabama, and Mississippi coastal plain regions with disjunct populations in western Cuba.[5]. It is considered critically imperiled in Georgia.[6]
Ecology
Habitat
In the Coastal Plain, T. chrysophylla habitats include longleaf pine-oak-wiregrass woodlands, sand pine scrubs, pine/wiregrass communities, scrub oak wiregrass sandhills, and upland turkey oak longleaf pinewoods. It has been found in disturbed areas such as along logging roads, a clear cut disturbed longleaf pine scrub oak ridge, an open sand ridge plowed three years previously, a bulldozed clearing in turkey oak longleaf pine, a sandy old quarry, a clobbered slash pine forest, and coarse sandy clearing of longleaf pine scrub oak barren. Soil types include loamy sand, sand, and sandy peat.[7]
Associated species include Balduina angustifolia, Dalea feayi, and Polygonella robusta.[8]
In central Florida T. chrysophylla exhibited no significant response to soil disturbance by bracke seeding, high-severity burns, and salvage logging. However, it increased its cover in response to soil disturbance by single roller chopping and broadcast seeding.[9] This species had mixed responses to clearcutting in central Florida. It has shown both regrowth and been unaffected in reestablished sand pine scrub that was disturbed by clearcutting.[9] T. chrysophylla reduced its frequency and biomass in response to soil disturbance by roller chopping in northwest Florida sandhills.[10]
Tephrosia chrysophylla is an indicator species for the Peninsula Xeric Sandhills community type as described in Carr et al. (2010).[11]
Phenology
T. chrysophylla has been observed to flower June through September with peak inflorescence in August and fruiting May through October.[7][12]
Fire ecology
It has been observed growing in burned pine flatwoods.[7]
Pollination and use by animals
Sweat bees such as Nomia maneei (family Halictidae) and leafcutting bees such as Megachile brimleyi and M. georgica (family Megachilidae) were observed visiting flowers of Tephrosia chrysophylla at the Archbold Biological Station:[13]
Flowers develop pink striation after being pollinated.[14]
