exposed to the sun, and it, without much care afterwards, 
continued to flourish a number of years. With a peat

SAXIFRAGA.—Saxrrace. 
(Named from sarum, a rock, and frango, to break, many of the species 
growing in the clefts of rocks.] 
A genus which comprises a number of Alpine plants,

white, arranged in corymbs on the ends of the branches, 
which, collectively, form a sort of panicle; April and 
May; perennial. This sweet flower is associated with my 
youthful floral rambles for May flowers. 
§. crassifélia.—A hardy perennial border flower with 
broad, thick leaves, rising from the root, from which are 
thrown up thick fleshy stems one foot high, with panicles 
of pink flowers in May and June. 
§. umbr6sa.—London-Pride.—This is a beautiful peren-

panicles, white or flesh color, dotted with yellow and dark-
