remedy consists in avoiding, as far as possible, an irregular com¬ 
position of the atmosphere as regards heat and moisture; and 
also an excess or deficiency of moisture in the soil, so that each 
may be in a condition to exert its proper influence on the con¬ 
stitution and development of the plants.” 
For the guidance of those who are unacquainted with the 
more rare and beautiful species of Erica, a select list and the 
shape of the flower will be given. 
Before closing this subject, one which has lately excited con¬ 
siderable emulation amongst cultivators, I have only to observe 
that what has been stated is from actual practical experience : 
each operation has been treated of in as graphic and compre¬ 
hensible a manner as possible; and should the course of ma¬ 
nagement be adopted as has been here recommended, there can 
be but little doubt of ultimate success. 
LIST OF NEW PLANTS. 
Aristolochie^jc. — Gynandria Hexandria. 
Aristolochia ornithocephala. There are few plants which present more 
striking peculiarities of form and structure in their blossoms than the various 
individuals of the genus to which the present plant belongs, which is a most 
remarkable one of the group. It is a large climbing plant with petiolated 
large leaves, in shape between cordate and reniform ; the flowers are solitary, 
the perianth very large, dingy yellow, the tube at the base inches long, 
obovate, inflated, marked with large black-purple reticulations; at the upper 
end this tube suddenly contracts, and is bent down at an angle; and this 
may be considered the base of the limb, which now becomes two-lipped. 
The upper lip is 5 inches long (resembling, with the inflated tube, a bird’s 
head and beak): the lower lip has a narrow stalk, 2 inches long, which sud¬ 
denly expands into an immense, reniform, beautifully reticulated, waved 
lamina, 4 inches long and 6 inches broad, the reticulations finely marked 
with deep purple on a pale yellow ground. It was raised in the Glasgow 
Botanic Garden from seeds gathered near Crato, Brazil, by Mr. Gardner, in 
September, 1838. — Bot. Mag. 
Gesneriacete. — Didynamia Angiospermia. 
Gesneria Gardneri. Discovered by Mr. Gardner, on the Organ Mountains 
of Brazil, in March, 1841, and raised from seeds at the College Botanic 
Garden, Dublin, where it bloomed in July, 1844. It is very distinct from 
any species hitherto described, and remarkable for the thick fleshy leaves, 
shaped not unlike those of the elm, pale coloured and with prominent nerves 
beneath. The flowers are solitary, of a pleasing carmine tint, proceeding 
from the axils of the leaves. — Bot. Mag. 
BoRAGiNEiE. — Pentandria Monogynia. 
Myosotis azorica. This beautiful Forget-me-not is found about waterfalls 
and on wet rocks with a north-east aspect, in the islands of Corvo and
