The word, Cerastium, is derived from the Greek 
keras, a horn, which is intended to apply to the 
form of the capsules of many of the species. The 
specific name is adopted in honour of Marschall 
von Bieberstein, a Russian botanist of celebrity. 
Amongst the species of Cerastium, which are very 
numerous, only a few can be considered as subjects 
well suited to the flower garden. This species, how- 
ever, is a highly desirable one, which, from th*.size 
of its flowers, and the free production of them, be- 
comes very shewy ; and it continues its attractions 
during several weeks. 
This, probably, is the true species of De Candolle, 
but, certainly, not that of Dr. Hooker. Having 
lost our plant soon after the drawing was made, we 
are left in a little uncertainty regarding it, but we 
shall recur to the subject at a future opportunity. 
This is a very suitable subject for putting out on 
artificial rook-work, where it will be kept tolerably 
dry. It should be frequently divided; or it may be 
struck from cuttings; and a plant or two should be 
protected in the cold frame, during winter, as a re- 
serve to meet unexpected losses.
