338 SELECT PLANTS FOR INDUSTRIAL CULTURE 



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. According to Morton it 

 is not so much sought and relished by grazing-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 Californian Clovers would deserve a 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. Peren- 

 nial. This species is much cultivated in Upper Italy ; its value is 

 that of T. medium (Langethal). 



Trifolium Pannonicum, Jacquin. 



The Hungarian Clover. Perennial. Earlier in the season than 

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

 (Morton). 



Trifolium pratense, Linne.* 



The ordinary Red Clover. All 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. The perennial variety passes under the name of Cow-clover, 

 by which name also T. medium is sometimes designated. Highly recom- 

 mendable for permanent pastures, particularly in cool humid climes, 

 as it continues to grow year after year and produces a large amount 

 of herbage (Dr. Curl). It prefers rich soil, and particularly soil 

 that is not devoid of lime ; gypsum dressings are recommendable 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. Nectar sucked by humble bees, 

 which also tends to facilitate the production of seeds. 



Trifolium reflexum, Linne.* 



North America. The Buffalo or Pensylvanian Clover. Annual 

 or biennial ; flower-heads larger than those of the Red Clover ; 

 likes alluvial flats. 



Trifolium rep ens, Linne.* 



The ordinary White Clover. Europe, North Africa, North and 

 Middle Asia, Sub- Arctic America. Perennial. Most valuable as 

 a fodder plant on grazing land. It has a predilection for moist soil,
