This variety of clover is more erect and less branched in its habit of
growth than the Japanese variety _Lespedeza striata_. Under Michigan
conditions it was found to grow to the height of 3 feet on sandy soil
and to about half that height on clay soil, the seed having been sown
about the middle of May. The stalks are about the same in structure as
those of alfalfa, and like alfalfa they do not lodge readily. The leaves
are ovate in form and of a pea-green tint. The seed is formed in pods
resembling those of lentils, only smaller. The seeds are larger than
those of crimson clover and are oblong in shape. In color they are
mottled brown, yellow and green. The roots in the Michigan test produced
nodules freely and without inoculating the soil by any artificial means.
The plants in the same tests were killed to the ground by early October
frosts.
This variety, like that grown so freely in the Southern States, is an
annual. In the absence of experience in growing it under varied
conditions, it would be premature to dwell upon its value. If it should
grow readily on sandy land, as the Michigan test would seem to indicate,
it would render substantial service in fertilizing such soils. In the
grass garden of the Department of Agriculture at Washington, D. C., its
behavior has been such as to encourage making further tests.
FLORIDA CLOVER
Florida clover (_Desmodium tortuosum_) is sometimes grown both for hay
and pasture, more especially in the Gulf States. It has been designated
botanically _Desmodium molle_, and is also known by the common names
Beggar Weed, Giant Beggar Weed, Beggar Ticks and Tickweed. The name
Florida Clover has been given to it because of its prevalence on the
light soils of Florida. The name "beggar" has probably been applied to
this plant because of its relation to poverty in soils, in which it is
more commonly grown, and the name "ticks" from the clinging habit of the
seed-pods to surfaces with which they come in contact.
Beggar Weed is an erect and branching plant, which grows from 2 to 10
feet high. The branches are woody in character, especially in the lower
parts, which prevents close cropping by animals grazing on the plants.
The trifoliate leaves are numerous, especially on the upper portions.
The panicle is erect and is considerably branched. The pods are prickly
and have many joints. These break asunder when matured, and are
frequently distributed by adhering to the covering of animals and the
clothing of men. The strong, spreading roots have much power to gather
food in the soil and also to enrich the same by means of the tubercles
formed on the roots.
