Trifolium incarnatum, Linn&* 



The Carnation-Clover, also called Crimson or Italian Clover. 

 Southern Europe, extending naturally to Switzerland. In Norway 

 it can be grown to lat. 70 22'. Though annual only or sometimes 

 biennial, it is valued in some of the systems of rotations of crops. 

 In the south of England it is much sown on harrowed stubble-fields, to 

 obtain an early feed of great fattening value. Sown in autumn it 

 will keep green all through winter even in cool countries and will 

 bloom early in spring. It forms particularly a good fodder for sheep, 

 and is recommended especially for gypsum-regions. With particularly 

 facility to be cut for hay ; also suited for ensilage and green manure. 

 Seeds well. It is quite ornamental and easily naturalised. A white- 

 flowering variety exists. Bees are very fond of this clover [Darwin]. 



Trifolium medium, Linn. 



The Bed Zigzag-Clover. Europe, Northern and Middle Asia. 

 Indigenous in Norway to lat. 63 26' [Schuebeler]. A deep-rooting 

 wide-creeping perennial herb, much better adapted for dry sandy 

 places than T. pratense. It would also endure the inclemency of 

 the clime of alpine heights, if disseminated there ; also one of the 

 best of clovers for forest-regions. For regular culture it needs lime, 

 Jike 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. Richard) is an allied plant from Abyssinia, 

 where several endemic species exist. 



Trifolium montanum, Linn&. 



Europe, Western Asia. Perennial. Not without importance for 

 limy or marly ground. It is indigenous northward to Christiania. 



Trifolium ochroleucon, Hudson. 



Pale-yellow Clover. Middle and Southern Europe, Western Asia. 

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

 is that of T. medium [Langethal]. 



Trifolium Pannonicum, Linne. 



The Hungarian Clover. Southern Europe. Perennial. Earlier 

 in the season than red clover, to which it is allied, but less tender in 

 foliage [Morton]. 



Trifolium pratense, Camerarius.* 



The ordinary Red Clover. All Europe, North- Africa, Northern 

 and Middle Asia. It is found wild as far north as 69 20' in Norway 

 [Schuebeler] ; an Alpine variety exists. A biennial, or under certain 

 circumstances also a perennial herb, of special importance for stable- 

 fodder. The perennial variety passes under the name of Cow-clover,
