(A) Rabbit-foot Clover; Stone Clover (Trifolium 
arvense ) (European). The stalk of this species is soft, 
silky and from 4 to 10 inches high. The light green 
leaves have three leaflets with blunt tips. The flower 
heads are composed of numerous florets; it is the long, 
pink, feathery tips of the five-parted calyx that gives 
the blossom its silky fuzziness; it is quite fragrant and 
is Visited by the smallest butterflies. You may find 
this species everywhere within our range. 
(B) Red Clover (Trifolium pratense) is the most 
common and the most valuable species of clover. One 
would hardly believe, knowing how abundant it is in all 
parts of our range, that this clover could have been 
introduced and have become so widely distributed, yet 
such is the case. One reason that it does so well in 
this country is that we have a very large number of 
bumblebees, and it has been found that clover is so de¬ 
pendent upon these insects for fertilization, that, with¬ 
out them, it will soon die out. 
The little florets, composing the globular flower-liead, 
are bright crimson-pink. The three leaflets that make 
up each leaf, have whitish-green triangles in the middle.
