those of the common V. Style with a 

 tuft of hairs under the stigma on the 

 outer side. Pod 1 to 1\ inches long, 

 about 4 lines broad, usually more or less 

 hairy. Seeds 4 to 6. 



In bushy or stony waste places, chiefly 

 near the sea, but spreading inland as a 

 cornfield weed, in southern Europe to 

 the Caucasus, extending up western 

 France to Bordeaux, and reappearing in 

 the south-western counties of England. 

 Fl. summer.

XVIII. PEA. LATHYKUS. 



Herbs, with weak stems, sometimes climbing, and half-sagittate or 

 sagittate stipules ; the leaves usually pinnate, with few leaflets larger 

 than in the Vetches, the common leafstalk ending in a simple or branched 

 tendril or in a small point, the leaflets sometimes wanting. Flowers 

 solitary or in racemes, on axillary peduncles, purple, red, white, or 

 bright yellow. Petals usually broad, especially the standard. Upper 

 stamen free, or more frequently connected with the others, at least in 

 the middle. Style flattened below the stigma, quite glabrous on. the 

 outer side, but more or less downy on the inner face for some way below 

 the stigma. Pod cylindrical or flattened. Seeds several, usually glo- 

 bular or angular. 



A considerable genus, with the wide geographical range of the Vetches, 

 differing from them chiefly by the style, and, in most cases, by the fewer 

 and longer leaflets and broader petals. The calyx is usually more ob- 

 lique, the upper teeth shorter than the lower ones. Several species 

 are very apt to dry black, which is seldom the case with the Vetches. 



Leafstalks without real leaflets. 



Stipules large and leaf-like. Leafstalk a mere tendril. 



Flowers yellow 2. Yellow P. 



Stipules none. Leafstalk flattened, resembling a grass- 

 leaf. Flowers pale-red 1. Grass P. 



Leaves with one pair of leaflets. 



Annual, with small red flowers. Pods hairy . . , . 3. Rough P.
