requires only one stick in the centre. Last spring I had them 
five feet high, growing in pots the size called 16’s, and branched 
to the top of the pot, forming a beautiful pyramid. I use the 
same soil for both that I use for the Mignionette. 
In conclusion, I can only add, that if any of your readers have 
not seen the above cultivated in pots for flowering in spring, they 
should lose no time in growing them, not doubting but they will 
be amply repaid for their attention. As many will have the Ne- 
mophila and Schizanthus in store pots for planting out in March, 
in the flower garden, they have only to select a few of the 
strongest, and repot them ; they will have good plants in a short 
time.

ON THE GENUS IPOMEA. 
BY MR. R. PLANT, OF PADHOLME NURSERY, PETERBOROUGH. 
This genus, containing as it does some of the most splendid of 
our exotic climbers, appears particularly deserving a notice in the 
Florist’s Journal, several of the species possessing claims of no 
mean order, not only for their extreme beauty, but also for their 
usefulness, as being appropriate ornaments not only of the stove, 
but also the greenhouse, however small, and even the open air, if 
supplied with proper soil and a good situation. A brief notice of 
some of the most prominent species may not prove uninteresting, 
in doing which I will mention the best modes of treatment I am 
acquainted with, though the cultivator must bear in mind, when 
reading a treatise on any particular plant, that such treatise is 
only the method of the person who writes, and if the reader can 
improve on or alter it to suit his own convenience, provided the 
plant is not the worse for such alteration, to him a great share of 
credit belongs. / 
T. Horsfallii is certainly one of the most magnificent climbers 
we possess ; for this, a stove is indispensable, indeed the roof of 
a house devoted to Orchidacese seems its most natural place, and in
