Lathyrus pratensis - Meadow Vetchling

Phylum: Magnoliophyta - Class: Equisetopsida - Order: Fabales - Family: Fabaceae

Lathyrus pratensis

This scrambling perennial plant can grow to 1.5m in height, supporting itself by clinging to more sturdy plants, hedges or fences using the tendrils at the terminal points of its leaves. Usually, however, plants are much shorter - typically 0.3 to 0.6m in height.

Description

Long upright squarish stems bear short spike-like racemes of 5-12 bright-yellow flowers. The individual flowers are 12-18mm long and have five yellow petals backed by five small green sepals. The upright petal forms the 'standard' with two lateral petals forming the wings, while the final two petals are fused and form the 'keel'. Flowers eventually produce pea-like black seed pods 25-35mm long.

There are short-stalked alternate leaves with a pair of arrowhead stipules (see picture below); each leaf comprises one pair of lanceolate leaf blades and a terminal leaf modified to form a (usually) unbranched tendril.
