PEA AND BEAN TRIBE. 



167 



neatb ; stipules half -arrow-shaped ; stem simple, erect, 

 winged. Woods ; not uncommon, especially in the 

 west of England. A pretty spring Vetch, with clusters 

 of blue and purple flowers in the axils of the leaves, 

 growing in similar situations with the Wood Anemone, 

 but appearing somewhat later. It may at once be dis- 

 tinguished from any of the true Vetches by its being 

 destitute of tendrils, the place of which is supplied by 

 a soft bristle-like point. The roots are tuberous, and 

 are "eaten by the Highlanders, under the name of 



ORNITHOPUS PERPUSILLUS (Common Bird's~/oot).
