88 FLORICULTURAL NOTICES. 
There are two important principles in tlie treatment of plants affected by frost., 
which should never be forgotten by the cultivator. First, they must not be 
subjected to a higher temperature till the frost is expelled; and secondly, this 
expulsion must be effected in the gentlest manner, and by the tardiest means, 
which can be conceived. To allow the vital fluids of plants to remain congealed 
for any length of time, is highly dangerous ; and to dissolve them too rapidly, is 
equally so. No restorative, therefore, can be eflicient, unless promptly applied ; 
and none is so appropriate as cold water. When this fails, it must not thence be 
supposed that it is useless, but that the frost had been too violent and destructive 
to admit of reparation.

NEW AND RARE PLANTS, FIGURED IN THE LEADING BOTANICAL PERIODICALS FOR 
APRIL. 
CLASS I.— PLANTS WITH TWO COTYLEDONS (DICOTYLEDONE^). 
THE INDIAN FIG TRIBE {Cactdcea). 
Epiphyllum russellianum. The Duke of Bedford's Epiphyllum. There is 
little to distinguish this most interesting new species from the well known E. trun- 
catum. It is rather more slender in habit, and has flowers of a somewhat deeper 
hue, but the principal difference is in the structure of the blossoms, which, in those 
of the present plant, is perfectly regular, consisting of an imbricated series of equal 
petals. The colour of the anthers is also dark red, those of E. truncatum being 
white. On the Organ mountains of Brazil, this species was discovered by Mr. 
Gardner, and forwarded to the superb collection of His Grace the Duke of Bedford. 
It grows on the branches of trees, or upon rocks, and would appear to be somewhat 
m.ore hardy than E. truncatum^ as it is found at a much greater altitude. Bot. Mag.

THE MEZEREUM. TRIBE ( Thymelacece.) 
PiMELEA henders5nii. Of the many lovely species of Pimelea which adorn 
our greenhouses, this seems to be the most ornamental, with regard to the size of 
the head of flowers, and their rich rosy-pink colour. The leaves are small, linear- 
lanceolate, smooth, and mucronulate, but apparently placed at a gTeat distance 
from each other, thereby leaving the stem too bare. Though a strong-growing 
plant, it flowered in great profusion, when only eighteen inches high, in the month 
of July, 1838 ; having been raised by Messrs. Eagle and Henderson, near Edin- 
burgh, from seeds sent to them by Captain Cheyne, from King George's Sound.
