greater certainty of its being correctly ascertained. 
This plan of naming hybrid productions we sug- 
gested, in this work, several years ago ; some of our 
contemporaries have used it, and, we hope, from 
the advantages it offers to the florist, as well as the 
scientific botanist, it may be generally followed, 
until a more advantageous method can be pro- 
posed, which, when it is, we shall have pleasure in 
adopting. 
The genus Cineraria has become highly attractive, 
from the superior seedling varieties which have of 
late been raised. Mr. Waterhouse’s plant first 
called attention to the capabilities of the genus, 
and this is being followed up with considerable 
attention by many ingenious gardeners and ama- 
teurs. They are most desirable ornaments for the 
greenhouse, and equally so as window plants, 
demanding but little care, and producing blossoms 
for a considerable length of time. 
It should be planted in a rich soil, have plenty 
of pot room when it is about to flower, and be 
occasionally watered with liquid manure. After 
the flowering season is over, the offsets should be 
divided, and planted singly, in small pots. Cine- 
rarias are very subject to be attacked by the aphis 
in spring ; when this occurs, they must be timely 
fumigated. With single plants, this is most easily 
accomplished by putting them into a close box, and 
introducing the bowl of a lighted tobacco pipe, and 
blowing it till the box is fdled with smoke. It may 
then be kept close for an hour, when the plant 
should be taken out; and, on the following day, be 
well watered over head, and thereby cleaned.
