Description

This is a small annual herb producing stems usually only a few centimeters long. The small leaves are made up of widely spaced leaflets with notched tips. The inflorescence arises on a rough-haired peduncle and holds up to ten pealike flowers. Each flower is about a centimeter long and colored white, yellow, or pale lavender, sometimes with light purple streaks. The fruit is an oval-shaped legume pod up to a centimeter long armed with a sharp beak. It contains 2 to 6 beanlike seeds.[1]
