| Lathyrus venosus | |
Lathyrus venosus is a species of flowering plant native to North America. It is part of the botanical family Fabaceae and is commonly known as veiny pea. [2] [3]
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]
Lathyrus venosus grows naturally in most of southeastern continental Canada and eastern continental United States. [a] [7] It generally grows in pine and prairie woodlands, along streams, on rocky slopes and roadsides, and in sandy ground. [2] [4]
The plant is globally secure, although in some parts of its range it may be at a lower status locally. [1] [4]
Common names include veiny pea, [2] [3] veiny vetchling, [4] [8] bushy vetchling [9] forest pea, [10] smooth veiny-pea, [10] smooth veiny peavine, [8] and gesse veinée (in French). [8]
