BERSEEM Trifolium alexandrinum 
Berseem is an annual white-flowered clover, much cultivated in the valley of the Nile 
in lower Egypt as a winter annual. As it is destroyed when the temperature falls to about 
18° Fahrenheit, it can be grown in most of the United States only as a summer annual. 
Does not yield so well as Alsike or Red Clover. May be utilized in Texas as a winter 
legume in short rotations. | 
BIENNIAL WHITE SWEETCLOVER Melilotus alba 
Extensively grown in north and northwest Texas grain and cattle grazing sections for 
its value as temporary pasture and a soil improvement crop. Will grow wherever alfalfa 
is adapted. Best used for spring planting in oats and on limestone soils too shallow for 
the best growth of alfalfa and Red Clover. Grows two years from one seeding and often 
attains a height of 10 ft. in the early spring of the second season. Plants develop fleshy 
deep penetrating roots. Highly prized as a bee plant. 
BLACK MEDIC (Yellow Trefoil) Medicago Iupulina 
A biennial winter-hardy pasture legume, more closely related to alfalfa than the bur- 
clovers. Only adapted to moist, fertile, well-drained limestone soils. It takes the place of 
bur-clover where greater cold-resistance is required and is very suitable for sowing with 
Bermuda grass, Dallis grass, Kentucky bluegrass, and Ryegrass pasture to furnish grazing 
and maintain soil fertility. It will stand heavy grazing and trampling. Plants produce a 
dense, thick growth of short, creeping to sub-erect, soft, succulent, fine, leafy stems 
readily recognized by the small yellow flowers and the black one-seeded pods. 
CALIFORNIA BUR-CLOVER Medicago hispida 
So called because the seeds are enclosed in pods which have short spines or burs. 
The most valuable and most used of the winter bur-clovers for permanent pasture in 
Bermuda Grass. Dallis and Carpet Grass to furnish abundant green grazing while these 
grasses are dormant. It maintains the soil fertility and succeeds best on soils relatively 
high in lime, moist and well drained. The trailing leafy stems are readily grazed by all 
classes of livestock. Sometimes used as a green manure crop. In contrast to alfalfa and 
Black Medic, bur-clovers have a shallow, spreading root system enabling them to grow 
readily on sod land. For best results, use hulled, scarified seed of known variety and origin.
