Florida prairie-clover is a suffrutescent (having a stem that is woody only at the base; somewhat shrubby) shrub 3-6 feet (0.5-2.0 meters [m]) tall (Bradley and Gann 1999, p. 42; Chafin 2000, NA). Bradley and Gann (1999, p. 42) described it as follows: Leaflets 15-23, ovate to elliptic, 5-14 mm [millimeters] long, glandular punctuate beneath; spikes subcaptitate to shortly oblong, 0.5-1.5 (-2) cm long, pubescent; peduncles opposite the leaves, terminal or appearing axillary, 1-3.5 cm [centimeters] long; bracts shorter than calyx; calyx 5-7 mm long, subequal and exceeding the tube, plumose; corolla subpapilionaceous, initially greenish white, turning maroon or dull purple, 4-5 mm long; stamens 9-10 (Adapted from Isely 1990).
Distribution & Occurrence
This shrub is found in pine rocklands, edges of rockland hammocks, coastal uplands, and marl prairie (Chafin 2000, NA). Bradley and Gann (1999, p. 42) stated, Fire is probably very important to the livelihood of this taxon. Plants probably do not tolerate shading by hardwoods in the absence of periodic fires. Two of the extirpated occurrences were reported from rockland hammocks (Castellow and Cox Hammocks). Plants probably occurred at the edges of these hammocks. At least one of the Palm Beach collections was made in some type of coastal upland.
In 1999, each of the five occurrences known at that time were located in slightly different habitat types: disturbed pine rockland, pine rockland / rockland hammock ecotone, pine rockland / rockland hammock ecotone along road edges, edge of roadside in marl prairie, and ecotone between rockland hammock and marl prairie and flatwoods (Bradley and Gann 1999, p. 43). In 2007, Jimi Sadle (NPS, pers. comm. 2007) characterized one occurrence in Big Cypress National Preserve (BCNP) at an ecotone between pineland and hammock. Florida prairie-clover occurs in association with south Florida slash pine (Pinus elliottii var. densa), live oak (Quercus virginiana), gumbo-limbo (Bursera simaruba), poisonwood (Metopium toxiferum), willow bustic (Sideroxylon celastrinum), white stopper (Eugenia axillaris), bluestem grasses (Schizachyrium spp.), and paspalum grasses (Paspalum spp.) (Bradley and Gann 1999, p. 43).

Vulnerability to natural disturbances
Invasive plant species
Due to its restricted range and the small sizes of most isolated occurrences, this species is vulnerable to environmental (catastrophic hurricanes)
