LEGUMINOSAE (PULSE FAMILY) 249 
starved by close, repeated, and persistent cutting throughout the 
growing season. Or, as the finely downy foliage is somewhat sus- 
ceptible to injury from chemical sprays, leaf-growth may be held 
in check and seeding prevented by this means, but the treatment 
must be repeated as often as the plants make recovery from the 
roots. 
HAIRY VETCH 
Vicia villosa, Roth. 
Other English names: Winter Vetch, Hairy Tare. 
Introduced. Annual or biennial. Propagates by seeds. 
Time of bloom: May to September. 
Seed-time: June to October. 
Range: Locally in most parts of the country, but most common in 
the southern states from Pennsylvania to Georgia. 
Habitat: Fields, roadsides, and waste places. 
Hairy Vetch is frequently planted for a cover crop or for fodder, 
and is inclined to persist or to escape to roadsides and waste places. 
It resembles the Cow Vetch in form and habit, but is covered all 
over, stems, leaves, and even flower-stalks and pods, with persistent, 
long, soft hairs. Stems one to three feet long, with short, petioled 
pinnate leaves having lance-like stipules and twelve to twenty 
oblong leaflets, which are obtuse or varying to lance-shape or 
linear. Racemes three to six inches long, many-flowered, with 
rather short peduncles; the blossoms are violet and white, often 
nearly an inch long — almost twice the length of those of Vicia 
Craeca, — with calyx-lobes bristly hairy on the lower side and the 
corollas not so slim, with standard and wings somewhat more 
spreading. The hairy pods contain six or eight small, dark, 
globular seeds. 
Means of control 
Destroy winter plants by hoe-cutting or by surface cultivating 
of the ground, or they may be grazed off in early spring. Prevent 
seed development by cutting while in first bloom — and, if abun- 
dant, curing for hay. All waste-land and roadside plants should 
be destroyed. ‘
