Description
O pendunculatum is a perennial forb/herb of the Fabaceae family native to North America.[1] Its flowers are 5-7 mm long and the calyx tube, fruits, and bracts are eglandular.The calyx's hairs are 0.7-1.0 mm long. The upper teeth are 1.0-1.5 mm long, the lateral teeth are 1.2-1.5 mm long, and the lower tooth 1.7-2.0 mm long. The bracts are 5-8 mm long and 1.0-2.5 mm wide, with a narrowly ovate shape. The leaves are pinnately 3-foliolate while the leaflets are eglandular, 0.8-2 cm wide, and 2.5-7.5× as long as wide.[2]
Distribution
O pendunculatum ranges from southern Ohio, southern Indiana, southern Illinois, central Missouri, and southeastern Kansas to southwestern North Carolina, south-central South Carolina, southwestern Georgia, western Panhandle Florida, southern Alabama, southern Louisiana, and eastern Texas.[2]
Ecology
Habitat
