 Trifolium incarnation, L. 



The Carnation- Clover. Middle and South Europe. Though 

 annual only, it is valued in some of the systems of rotation 

 of crops. It forms particularly a good fodder for sheep. A 

 white flowering variety exists. 



Trifolium medium, L.* 



The Red Zigzag Clover. Europe, North and Middle Asia. 

 A deep-rooting perennial hero, much better adapted for dry 

 sandy places than T. pratense. It would also endure the 

 inclemency of the clime of our higher alpine regions if 

 disseminated there. T. Quartinianum, A. Eich., is an allied 

 plant from Abyssinia, where several endemic species exist. 



Trifolium pratense, L.* 



The ordinary Eed Clover. All Europe, North Africa, North 

 and Middle Asia, extending to Japan. A biennial or under 

 special circumstances also perennial herb, of great import- 

 ance for stable-fodder. It prefers rich soil and particularly 

 such, which is not devoid of lime. Also this species would 

 live in our alps, where it would much enrich the pastures. 



Trifolium repens, L.* 



The ordinary White Clover. Europe, North Africa, North 

 and Midele Asia, sub-Arctic America. Perennial. Most 

 valuable as a fodder-plant on pastoral land. It has a predi- 

 lection for moist soil, but springs again from dry spots after 

 rain. It has naturally spread over many of our humid 

 valleys, and its growth should be encouraged in such 

 localities. 



Trifolium subrotundum, Hochstett. 



The Mayad-Clover. North and Middle Africa, ascending to 

 9000 feet. A perennial species, in its native countries with 

 advantage utilized for Clover-culture. This by no means 

 closes the list of the Clovers, desirable for introduction, 

 inasmuch as about 150 well-marked species are recognized ) 

 many doubtless of pastoral value. But the notes of rural 

 observers on any of these kinds are so sparingly extant, 

 that much uncertainty about the yield and nutritive value 

 of the various kinds continues to prevail. Most Clovers
