Annual. June — August. 



A little, smooth, pale glaucous-green herb, branching from the 

 root into several weak stems, either procumbent, or climbing by 

 means of numerous, alternate, simple tendrils, each of which 

 springs from between a pair of large stipulas, of a broad arrow- 

 shape, nearly entire. There are no true leaves or lea/lets, ex- 

 cept that now and then, on young plants, near the root, a pair 

 of an elliptical sliape, on one or two rudiments of tendrils, very 

 rarely on a real tendril, may be observed. But these soon 

 wither away. F/. solitary, on long simple stalks, accompanying 

 some of the tendrils, small, drooping, lemon-coloured. Brac- 

 teas in pairs, awl-shaped. Teeth of the calyx long and lanceo- 

 late, ribbed. Legume about an inch in length, somewhat cylin- 

 drical, smooth, with about 6 round seeds. 



2. L. Nissolia. Crimson Vetchling. Grass Vetch. 



Stalks mostly single-flowered. Leaves simple, without ten- 

 drils. Stipulas awl-shaped.
