Enlarged. tan has produced a hardier and more drought- resistant crop than ordinary alfalfa, though appar- ently no hardier than Grimm and northern Montana seed. The forage is sweeter and has finer stalks than ordinary alfalfa. As seed production in the United States is difficult, the commercial seed is largely imported. Experiments indicate that it is slightly superior in the semi-arid West, where the moisture is sufficient for but one or two crops a season of ordinary alfalfa. Gri77im.âThis was first noted in Carver county, Minnesota, where it is hardy. It was introduced by the Minnesota Experiment Station. It is apparently slightly hardier than Turkestan alfjUfa. Perhaps identical with Sand lucerne. Dry-land.âThis is the name giren throughout the West to seed (especially Utah-grown) pro- £18 duced without irrigation in areas of light rain- fall.

The stems and leaves are pubescent. Sand Zwcern.âThis is thought to be a cross between Medicago saliva and M. fakata. It has been grown successfully by the Michigan and Wisconsin Experiment Stations. Its production is still in the experimental s
