42.4 FOREST CULTURE AND 
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 in- 
clemency of the clime of our higher alpine regions if 
disseminated «there, T. Quartinianum, A, Rich., is 
an allied plant from Abyssinia, where several endem- 
ic species exist. 
Trifolium pratense, L.—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 impor- 
tance for stable-fodder. It prefers rich soil, and par- 
ticularly that which is not devoid of lime. Also this 
species would live in our alps, where it would much 
enrich the pastures. 
Trifolium repens, L.*—The ordinary White Clover. 
Europe, North Africa, North and Middle Asia, sub- 
arctic America. Perennial. Most valuable asa fodder- 
plant on pastoral land. It hasa predilection for moist 
soil, but springs again from dry spots after rain. It 
has naturally spread over many of our humid valleys, 
and its growth should be encouraged in such locali- 
ties. 
Trifolium subrotundum, Hochstett. — The Mayad 
Clover. North and Middle Africa, ascending to 9,000 
feet. A perennial species ; in its native countries 
with advantage utilized for clover culture. This by 
no means closes the list of the clovers desirable for 
introduction, inasmuch as about 150 well-marked spe- 
cies are recognized, many, doubtless, of pastoral value. 
But the notes of rural observers on any of these kinds 
are so sparingly extant that much uncertainty about 
the yield and nutritive value of the various kinds con-
