THE STUDY OF THE SCIENCE OF BOTANY. 
The usual mode of propagating the carnation is by layers, though I 
have one now which will not strike from layers. This plant, which is 
the most splendid flower I should say yet produced, is a yellow ground 
crimson Bizarre, which I intend when in full bloom to have painted, 
and shall be glad to send it to the proprietors of this magazine, being 
a flower which will be the admiration of florists. There are at present 
only about a dozen layers of it, which, in October, the person from whom 
I procured mine will have a few to dispose of at 10s. Qd. per plant. 
Various times have been stated for layering, but the growers of 
carnations may take this for granted, the most proper time is as soon as 
they are ready.—I have several growing well, which were layered in 
the middle of May. I should recommend them to be taken off about 
the latter end of September, and potted singly in the compost, as above 
stated, and placed in a shed* protected from the cold winds ; but I should 
say, do not, on any account, put them under glass. Many recommend 
a frame, but, for my own part, I totally disapprove of it. These 
simple directions, if followed, I have no doubt will answer all the 
expectations of the growers of this beautiful flower.

Classis XII.— Icosandria. 
Icosandria , from ico, twenty, aner , a man. 
Bisexual flowers, furnished with many stamens or 
male organs of generation. 
To gardeners this is one of the most interesting of 
all the Linnoean classes, containing a greater propor¬ 
tion than any other of objects which come within their 
observation and management. It also consists of genera 
for the most part nearly allied, and comprises not only the most remark¬ 
able portion of Ficodea , all Cacti , and the chief of the Myrtacecz, but 
almost every genus of the beautiful and hardy tribes of Rosacea. 
The characters of this class are well defined, and entirely depend 
upon the insertion of a number of distinct stamens, above twenty, into 
the inner surface of the calyx. (See Classis XIII.)
