moved to other situations, and so would allow of keeping the 
house warmer than is ordinarily done. 
The soil they most delight in is a good sound turfy loam, en¬ 
riched with well-rotted hotbed dung; nor must they be allowed 
to grow too luxuriantly, if seed is an object sought; they may 
be grown in very large pots or tubs, though to plant them in the 
border of the house is by far the most preferable method. The 
plants should be occasionally syringed during the growing season 
to remove dust and prevent the approach of red spider, though 
they are but little subject to the attacks of any insect if kept in 
anything like a healthy state. The hardier species are those we 
should choose for the purpose of impregnation, as likely to im¬ 
part a hardy constitution to the hybrid; they are : 
P. Ccerulea ; P. Angustifolia ; and P. Chinensis. 
Of the other and more tender species the finest are :

There are many others, but this selection will suffice, for either 
ornament or improvement. P. Cerulea racemosa is an hybrid 
raised by the late Mr. Milne, of Fulham, and is considered to 
surpass in beauty almost all the natural species ; it is well suited 
for a greenhouse climber, but will not stand the severity of our 
winters in the open air. Alata cerulea is another hybrid of great 
beauty, obtained by Mr. Masters, of Canterbury, from seed of 
P. Alata of the West Indies, impregnated with P. cerulea; the 
same may be said of this as of Cerulea racemosa, it will not suc¬ 
ceed when planted in the open air. Now though an hybrid ob¬ 
tained from a cross between a hardy species and one that is 
tender does not appear to be strong enough to withstand our 
winters, yet there seems to be every probability of a successful 
issue if the hybrid so obtained was again crossed with a hardy 
species. That those hybrids will seed we have had proof, and
