332 SELECT PLANTS FOR INDUSTRIAL CULTURE 



Middle and Soutli Europe. Though annual only, or sometimes 

 biennial, it is valued in some of the systems of rotetions of 

 crops. In the south of England it is much sown on harrowed 

 stubble fields to obtain an early fodder of great fattening 

 value. It forms particularly a good fodder for sheep ; it is 

 recommended especially for gypsum regions. A white flower- 

 ing variety exists. Bees are very fond of it (Darwin) . 



Trifolinm medium, Linne.* 



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

 A deep-rooting, wide-creeping, perennial herb, much better 

 adapted for di-j sandy places than T. pratense. It would also 

 endure the inclemency of the clime of higher Alpine regions, if 

 disseminated 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 clo- 

 vers and grasses. According to Morton it is not so much 

 sought and relished by graaing-animals as many other Clovers. 

 T. Quartinianum (A. Rich) is an allied plant from Abyssinia, 

 where several endemic species exist. Some of the twenty-five 

 known CaUfornian Clovers would deserve test cultm-e. 



Trifolinm montannm, Linne. 



Europe, West Asia. Perennial. Not without importance for 

 limy or marly ground. 



Trifolinm ochrolencum, Linne. 



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

 Perennial. This species is much cultivated in Upper Italy ; 

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



Trifolium Fannonicnm, Jacquin. 



The Hungarian Clover. Perennial. Earlier in the season than 

 Red Clover, to which it is allied, but less tender in foliage 

 (Morton). 



TrifoKnm pratense, Linne.* 



The ordinary Red Clover. AU Europe, North Africa, North 

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

 special circumstances also perennial herb, of great importance 

 for stable fodder. It prefers rich soU, and particularly soil 

 that is not devoid of lime; gypsum dressings are recom- 

 mended for its fields. It enters very advantageously into the 

 rotation system of crops. This species also would live in 

 Alpine regions, where it would much enrich the pastures.
