forest edges, the stems, having downward hairs, going up
counterclockwise the other plants around. Leaves are composed of 3
leaflets, each 3-5cm long, 2.5-4cm wide, relatively thick, and on
the backsides, there exist lots of downward hairs and brown-yellow
granular dots. Flowers, light yellow, about 9mm in diameter, come in
a racemose way. Legumes ripen red to split open; insides expose two
black seeds. Bloom time: July-September |
