3. Vicia villosa Roth. Hairy Vetch. A villous pubescent 
much branched, weak and trailing, cultivated annual, or biennial, 
with a stem 2-6 ft. long and / 6 in. in diameter. Leaflets 8-24, 
linear, %-A in. long, %-%(, in. wide, obtuse at the base, acute at the 
apex; tendrils branched. Peduncle shorter than, or equalling 
the leaves; the flowers purple to white; the pod % to 1 in. long; 
/-/ in. wide; seed round and black. 
The seed of Vicia villosa may be distinguished by the lemon- 
yellow beneath the outside coating from the Vicia sativa, which is 
an orange-yellow. Vicia villosa is able to withstand the northern 
climate, while Vicia sativa is often winter-killed, so the ability 
to distinguish the seed is of importance. The Plairy Vetch is 
being experimentally used by many fanners over Ohio, as a soiling 
and hay crop.

very finely pubescent weak trailing perennial, 2-3 ft. long and
