Lagundi is an erect, branched
tree or shrub, 2 to 5 meters high. Leaves are usually 5-foliate, rarely with
3 leaflets only, and palmately arranged. Leaflets are lanceolate, entire, 4 to 10 centimeters long, slightly
hairy beneath, and pointed at both ends, the middle leaflets being larger than the others, and distinctly stalked. Flowers
are numerous, blue to lavender, 6 to 7 millimeters long, borne in terminal inflorescences (panicles) 10 to 20 centimeters long. Calyx is hairy, and 5-toothed. Corolla is densely hairy in the throat, and the middle lobe of the lower lip is longest. Fruit is a succulent drupe, globose, black when ripe,
about 4 millimeters in diameter.
