obtained by several nurserymen, and 
it was sold for several years at five 
guineas each. It is now common 
collections, but it is rather diffi- | 
lt to keep; as, though it requires 
a moist heat, it will die if its roots 
are suffered to retain any stagnant 
moisture among them, and it must 
not be plunged either in tan or ina 
hotbed. It is also very liable to be 
attacked by insects.

Jaca or Jack Tree.—A species

Jacara'NDA.— Bignonidcee. — A 
climbing plant, a native of Brazil, 
with beautiful lilach flowers, shaped 
like those of the Catalpa. The 
wood is said to be the rosewood of 
commerce. In England it requires 
a stove. It should be grown ina 
mixture of loam and peat, and it 
should be kept nearly dry during 
winter. 
It is propagated by cut- 
‘hich should not be deprived 
eaves, and which must be 
in pure sand under a glass. 
ersons suppose the rosewood 
e a kind of Mimosa.

should be grownin peat. They are 
easily propagated by cuttings.

is one of our most vigorous-growing 
wall-evergreens, though a native 
of India. There are several spe- 
cies hardy in British gardens, but 
the greater number require the 
greenhouse or stove. ‘The principal 
hardy species is that already men- 
tioned. It well deserves a place 
against the wall of a house, or the 
piers of a veranda, which it will 
cover ina very short time; or if 
planted agaist trellis-work, or 
against the frame-work of a bower, 
it will soon afford an agreeable shade, 
and produce its long, graceful, deep- 
green shoots, in such quantities, as, 
after covering the bower, to hang 
down to the ground all round it, and 
require to be separated like a cur- 
tain by a person entering. This 
plant and the common Ivy, when 
trained up a single post, with a 
spreading umbrella top of frame- 
work, form some of the finest ob-
