Description

Lathyrus venosus is a perennial vine with herbaceous stems, growing from a creeping rhizome.[4] The stems are climbing or sprawling and measure about 0.9–1.2 metres (3–4 feet) in length.[4] The leaves are alternate and even-pinnate with usually 8–12 leaflets, ending in a branched tendril.[4][5][6] Each leaflet is roughly oval in shape, is untoothed, and lacks hair.[4] The papilionaceous flowers grow from the leaf axils in clusters of 8–15. They are arranged in a raceme and are generally pink, purple, or blue.[4] The fruit is a hairless seedpod.[4]
