which have as yet been but little grown in this country, or of varieties of but local interest. The former are Sainfoin (_Onobrychis sativa_), Egyptian clover (_Trifolium Alexandrianum_), yellow clover (_Medicago lupulina_), Sand Lucerne (_Medicago media_), and a newly introduced variety of Japanese clover (_Lespedeza bicolor_). These may prove more or less valuable to the agriculture of the United States when they have been duly tested, a work which as yet has been done only in the most limited way. The latter include Florida clover (_Desmodium tortuosum_), more frequently called Beggar Weed, Buffalo clover (_Trifolium reflexum_), and Seaside clover (_Trifolium invulneratum_). These may be worthy of some attention in limited areas where the conditions are favorable, but it is not likely that they will ever be very generally grown. They are dwelt upon rather to show their small economic importance and with a view to prevent needless experimentation with plants possessed of so little real merit.
