DESCRIPTIVE LIST OF NEW PLANTS. 
branched. Leaves on rather long, stout petioles, ample, or- 
biculari-cordate, shining, five to seven lobed, the lobes sharp and 
grossly toothed; the teeth spinulose; corolla large, fulvous- 
yellow ; petals spathulate, spirally twisted, the apices spreading, 
obscurely toothed; and the stamens, with the copious anthers, 
form a cylinder beneath the large five-lobed stigma.— Bot. Mag.

AsclepiadEjE. —Pentandria Digynia. 
Hoy a bella (Hooker). The most lovely of all the Hoyas. It 
cannot be called a climber, but the branches are diffuse, copiously 
leafy, so that the leaves form a dark background to the delicate 
umbels of flowers ; the leaves in shape resemble those of a myrtle, 
and the flowers more lively and differently formed from those of 
Hoy a carnosa, and most deliciously scented. The corolla is a 
purer white, and the corona a deeper purple, resembling an 
amethyst set in frosted silver. It is a native of the Taung Kola 
mountain, Moulmein, and has been imported through their col¬ 
lector, Mr. Thomas Lobb, by Messrs. Yeitch and Sons, of 
Exeter. Where treated like an iEschynanthus or an epiphyte, 
we had the pleasure of seeing this ee first gem of the air” 
blossoming in great perfection in June 1848. It is a free 
bloomer, and the flowers last many days in high beauty.— Bot. 
Mag. 4402. 
LoBELiACEiE. —Pentandria Monogynia. 
Siphocampylos manetticeflorus (Hooker). This very pretty 
plant, for the bright red and yellow corollas contrast well with 
the glossy, dark green foliage, comes to the English gardens by 
way of Belgium, and we are indebted for the possession of the 
species to our friend, Mr. Low, of the Clapton Nursery. It is 
probably derived from New Grenada, and was received with the 
name of S. nitidus; but this appellation is, we should think, 
given to it in gardens in ignorance of the existence of a S. nitidus 
of Pohl (from Brazil), with which this has nothing to do. It is 
a free flowerer, and it has been in blossom all the spring, summer, 
and autumn in our stove. It is a small, erect, firm-growing 
plant, not exceeding a foot in height, suffruticose, leafy, branched. 
The leaves are alternate, and from their axils the peduncles pro-
