DESCRIPTIVE LIST OF NEW PLANTS. 
Acanthace.e— Didynamia Angiospermia. 
Ruellia macrophylla. This fine herbaceous plant is a native of 
Santa Martha, according to Vahl, who first discovered it. He 
supposed that it habitually produced only two flowers on a stalk, 
while, in fact, it bears large branching forked panicles, loaded 
with flowers of a glowing scarlet, and nearly three inches long. 
In that state it was exhibited at a meeting of the Horticultural 
Society in October last, by Mr. Carton, gardener to his Grace the 
Duke of Northumberland, and it was indeed worthy of the noble 
collection which furnished it. This species requires to be kept 
in a stove, and, being a plant of free growth, will succeed in 
almost any sort of soil. During summer an ample supply of 
water should be given to its root, and syringed over head twice a 
day. After flowering it should be cut back, to secure a supply of 
young shoots from the bottom for flowering the following season. 
This may be done once or twice, but for such free-growing plants, 
it is best to renew them every three years.— Bot. Reg. 7—46. 
Caprifoliace/e. —Rentandria Monogynia. 
Abelia rupestris. A small spreading bush, with deciduous 
bright green foliage. The branches are very slender, covered 
with fine down, and deep reddish brown when fully exposed to 
the sun. The leaves are opposite, ovate, distantly serrated, on 
very short stalks, quite smooth, except at the midrib, on the 
under side, where they are closely covered with short hairs. The 
flowers are pure white, (in the figure they are a pale rose colour,) 
something like those of the honeysuckle, and come in pairs from 
the axils of the leaves belonging to the short lateral branches. 
The corolla, when expanded, is half an inch long, funnel-shaped, 
downy, with a spreading border of fine convex, ovate, blunt, 
equal lobes, beyond whose tube extend four smooth filaments. 
From its being sweet-scented, and the length of time it remains 
in flower, this will be of considerable importance as a greenhouse 
plant, and, should it prove hardy, it will doubtless be a good 
addition to the shrubbery, in consequence of its flowering in 
autumn.— Bot. Reg. 8—46.
