Description, &c.— This very beautiful variety, though occasionally 
seen in our shrubberies, has, I believe, never been before figured. It is 
very double, and of a richer and deeper rose-colour than the common 
pink hawthorn; and when the trees are fully in flower, they look as if 
covered with clusters of fairy roses. Nothing can have a finer effect 
than one of these trees in early spring, standing on a lawn with a back¬ 
ground of green; or planted on the margin of a shrubbery. The whole 
genus Cratcegus is highly ornamental; some of the trees are remark¬ 
able for their large, yellow fruit, as, for example, C. Aronia and C. tana- 
cetifolia; in others the fruit is large, and of a deep coral red, as in 
C. odoratissima or C. orientalis; and in others of a deep claret colour, 
as in C. Douglasii. All the kinds have handsome foliage ; and in some, 
as in C. crus-galli and its allies, the leaves are shining, and of a rich, 
deep green. C. salicifolia has a naked trunk, with its branches forming 
a broad, spreading head, like that of the Italian stone-pine, and produces 
a striking effect in the landscape. I am induced to say more than perhaps 
I otherwise should on this subject, because this is the season for planting, 
and I am sure that if any of my readers should be induced to plant an 
additional tree or two of this genus from anything I can say, they will 
not repent having done so. Some of the species are nearly evergreen ; 
as, for example, the Washington Thorn (C. cordata ), mentioned in p. 352. 
These trees vary very much in their time of flowering; the flowers of 
C. purpureus appearing in March or April; and those of C. mrginica in 
July or August. C. spathulata and C. cordata are also very late in 
coming into flower; and C. nigra and C. glandulosa are very early.
