been furnished with swimming buoys, by passing their roots 
through a hole made in a piece of cork, and drawing the latter 
close up to the base of the bulbs; and thus they are now floating 
in the basin of the fountain, and appear to flourish in their new 
position most admirably. Their effect is eminently pleasing, 
and from my success in this matter, I have been induced to try 
them in another still more novel position. Some of the later 
bulbs were wrapped in a thick coating of moss, taking care the 
outer portion was fresh and green, and are suspended from the 
roof above the others; an occasional syringing is all the attention 
they have received, and the blooms are now most luxuriant, 
hanging in a graceful half-pendent manner from the ball of moss, 
which in itself is beautiful, being brilliantly green, and the long 
white roots of the Hyacinth protruding at bottom, increase the 
effect by giving each plant an epiphytal appearance.

Allamanda Schottii (Pohl.) Much confusion exists with re¬ 
spect to the different species of Allamanda , of which seven are 
enumerated in the Prodromus of De Candolle. The A. cathar- 
tica of Linnaeus is called A . Linncei by Pohl, and it is distin¬ 
guished as a species from the Allamanda Aubletii. These are 
again united by Alphonse De Candolle ; both have scandent stems. 
A. cathartica alone, so far as I know, had been introduced to 
our collections till September 1847, when I had the pleasure of 
receiving a specimen of a perfectly upright growing species from 
Mr. J. Stanton, gardener to R. W. Barton, Esq., Springwood, 
Manchester. They were raised from seeds sent by Mr. Graham, 
from Brazil, to Miss Barton. Besides the size, beauty, and co¬ 
piousness of the blossoms, this species has the merit of flowering 
when little more than two feet high, and in eight-inch pots. 
It is an erect, suffruticose plant; the leaves are in whorls of 
three or four, large, lanceolate, and spreading; the peduncles are 
terminal and from the axils of the leaves, bearing several flowers
