Trifolium glomeratum, Linne. 



Countries at or near the Mediterranean Sea, extending indigen- 

 ously to South-England. Will live even on sandy pastures, spreads 

 readily by dissemination on its own accord, helps to supplant Aveeds, 

 but fails in our autumn, when pasture-herbs are most wanted. 



Trifolium hybridum, Linne.* 



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

 Wild in Norway to lat. 63 50'. A valuable perennial pasture-herb, 

 particularly for swampy localities. It succeeds, where the ground 

 becomes too sandy for lucerne and too wet for red clover, but does 

 not withstand drought so well, while it produces a heavier bulk of 

 forage than white clover, and maintains its ground, when the soil 

 has become too much exhausted for other clovers. The best kind 

 for irrigation ; as nutritious as white clover, suitable for pasturage 

 as well as for mowing. The seed being very small, less than half 

 the quantity is required for the same area as of red clover. Much 

 frequented by bees for honey. 



Trifolium incarnatum, Linne.* 



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. It forms par- 

 ticularly a good fodder for sheep, and is recommended especially for 

 gypsum-regions. A white-flowering variety exists. Bees are very 

 fond of this clover [Darwin]. 



Trifolium medium, Linne. 



The Red 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, 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. Richard) is an allied plant 

 from Abyssinia, where several endemic species exist. 



Trifolium montanum, Linne. 



Europe, Western Asia. Perennial. Not without importance for 

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