linearis Wats.) and truncate-leaved (var. 
truncata Brew.) varieties, ranging with the 
species, have been described. Unlike most 
native vetches, which do not withstand graz- 
ing well, this is considered a useful forage 
plant. 
Vieia angustifolia Reich (NARROWLEAF 
veTcH)—A slender annual vine introduced 
from Europe, but naturalized throughout 
most of the Eastern States. The leaves have 
4 to 16 leaflets, and the flowers are purple. 
The common form of the plant in the South 
is a strain called Augusta vetch, much used 
aS a winter cover and green-manure crop. 
It is used as a pasture plant in Georgia, 
where it maintains itself by heavy reseeding 
year after year. To a limited extent it has 
been employed to control erosion on produc- 
tive field borders in the Southeast. 
_Vicia_ sativa - (CoMMoNn vetcH)—A 
vining Eurasian annual with stems 3 to 5 
feet long, also called English or smooth 
vetch and tare. There are many crop forms. 
The leaves have about 14 leaflets; the vio- 
let-purple to white flowers are usually in 
pairs on a very short stalk. It thrives in 
well-drained loamy soils and is a good soil 
improver. Thorough inoculation is neces- 
sary to produce a good stand on poor soil. 
Requiring a cool growing season, it is grown 
as a hay and silage crop in the Northwest 
and as a winter cover and green-manure 
crop in California, where it is also a seed 
crop of commercial importance. 
Vicia villosa Roth (Harry vetcH)—A 
slender twining European annual, often be- 
having as a biennial, with stems up to 12 
feet in length. It is very hairy, the leaves 
have 11 to 17 leaflets, and the blue-violet, 
rarely white, flowers are borne in long one- 
sided clusters. It is also known as sand 
vetch, villose vetch, Russian vetch, and win- 
ter vetch. It grows in a variety of soils, 
even clays, will resist more alkali than most 
legumes, and is markedly drought-resistant. 
Its chief uses are for hay, pasture, and

silage. Because of its weak stems it is usu- 
ally sown with a supporting crop of small 
grain. Adapted to a wide range of climatic 
conditions, but especially cold-resistant, it 
is mostly grown as a winter cover and green- 
manure crop. 
Vigna sinensis (CowpreA)—An annual 
more like a bean than a pea, with broad 
leaflets and long slender pods. Probably 
native to central Africa, it is now exten- 
sively cultivated throughout the southeastern 
United States and California. It is particu- 
larly valuable on poor, sandy soils and is 
grown for seed, hay, ensilage, and green 
feed. Its soil conservation value includes 
use as a cover and pasture plant and green- 
manure crop. In the warm humid parts of 
the Southeast only mildew-resistant varie- 
ties, such as Iron and Brabham, should be 
planted for wildlife, for which the seeds 
are usually available until midwinter. 
Voandzeia subterranea (CONGO GOOBER) ; 
—An African herb, with prostrate stems, 
from which arise upright trifoliolate leaves 
and small bright yellow flowers borne close 
to the ground. It has been sparingly grown 
in southern gardens for some time, and, 
like the peanut, buries its fruit underground 
before it ripens. It is widely cultivated by 
the natives of central Africa for its edible 
seed and is called Bambarra groundnut, hog- 
peanut, and goober. 
Wisteria — A genus containing half a 
dozen species of stout woody vines native 
to China, Japan, and eastern North America. 
They have compound leaves with 9 to 19 
leaflets and long drooping clusters of pur- 
plish, blue, or white flowers. Japanese wis- 
teria, W. floribunda D.C., native to Japan, 
is commonly cultivated as an ornamental in 
the United States and is considered one of 
the most attractive woody vines for temper- 
ate regions. Two species with lilac-purple 
flowers are native to the United States, 
namely, W. frutescens (L.) Poir. (W. spe- 
ciosa Nutt.), the American wisteria of the 
South Central and Southeastern States, and 
W. macrostachya Torr. and Gray, the Ken- 
tucky wisteria of the South Central United 
States. 
Zornia bracteata (BRACTED ZORNIA)—A 
perennial herb, with spreading or prostrate 
branches up to 3 feet in length, 2- to 4- 
foliolate leaves and yellow flowers in axil- 
lary or terminal bracted spikes. It occurs 
in sandy soil from Virginia to Florida, west
