Trifolium Alexandrinum, Linne.* 



The Bersin-Clover. North-Eastem Africa, South- Western 

 Asia, South Europe. Much grown for forage in Egypt. 

 Recorded as annual. 



Trifolium alpestre, Linne. 



Europe, West Asia. Perennial. Content with lighter soil 

 than that needed for most Clovers, but its constituents must be 

 fairly marly or limy. It is early out and very palatable 

 (Langethal). 



Trifolium fragiferum, Linne. 



The Strawberry-Clover. Europe, North Africa, Middle and 

 North Asia. A perennial species, well adapted for clay-soils. 

 Foliage closer and more tender than that of the White 

 Clover, but its vegetation later (Langethal). 



Trifolium hybridum, Linne.* 



The Alsike-Clover. Europe, North Africa, Western Asia. 

 A valuable perennial pasture -herb, particularly for swampy 

 localities. It succeeds where the ground becomes too sandv 

 for Lucerne and too wet for Hed Clover. 



Trifolium incarnatum, Linne. 



The Carnation-Clover. Middle and South Europe. Though 

 annual only, or sometimes biennial, it is valued in some of 

 the systems of rotations of crops. It forms particularly a 

 good fodder for sheep; it is recommended especially for 

 gypsum-regions. A white-flowering variety exists. 



Trifolium medium, Linn6.* 



The Ked Zigzag-Clover. Europe, North and Middle Asia. 

 A deep-rooting perennial herb, 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 dis- 

 seminated there. One of the best Clovers for forest-regions. 

 For regular culture it needs lime, like most plants of its 

 class. More hardy than T. hybridum, less productive than 

 T. pratense (Langethal). It ought not to be omitted among 

 mixed Clovers and grasses. T. Quartinianum (A. Rich) is an 

 allied plant from Abyssinia, where several endemic species 

 exist. Some of the twenty-five known Calif ornian Clovers 

 would deserve test-culture. 



Trifolium montanum, Linne. 



Europe, West Asia. Perennial. Not without importance 

 for limy or marly ground. 



Trifolium ochroleucum, Linne. 



Middle and South Europe, West Asia. Pale-yellow Clover. 

 Perennial. This species is much cultivated in L^pper Italy ; 

 its value is that of T. medium (Langethal).
