EXTRACTS—FLORICULTURE. 
and reposing upon the soft velvet bed formed by its succulent leaves, it is a 
most beautiful object, resembling C. pilosiuscula, but very far superior to it. A 
native of northern California, whence its seeds have been recently sent by Mr; 
Douglas. Culture.—It is a hardy annual, readily propagated by seeds, which it 
bears in great abundance. It loves dry and exposed situations, and flourishes 
most in scorching weather; but it should be grown in tolerably rich soil, or, if 
in very poor soil, it should be sown thick. Under the former circumstances, it 
forms a patch of a foot or more in diameter; in the latter case its branches are 
not above two or three inches long, as in the wild specimens in the Horticultural 
Society’s possession.— Bot Reg. 
hydrophyl.le.iE.—T he Water-Leaf Tribe. 
Nemophila aurita. —Ear-leaved Nemophila. Rather a pretty species, found 
in California by Mr.' David Douglas. It is a hardy, trailing annual, requiring 
a damp shady border, where it grows and flowers from May to the end of August. 
If sown in a place exposed to the sun, it soon withers and perishes. It is of very 
recent introduction by the Horticultural Society, and is at present extremely rare, 
but as it seeds tolerably freely, it will soon be more abundant. The flowers are 
purple.— Bot. Reg. 
scrophularine-iE. —The Figwort Tribe. 
Calceol'aria purpurea Elegans. —Elegant purple Slipper-wort. This 
beautiful variety was raised by Mr. Wheeler, nurseryman, Warminster, Wilts, 
from Chilian seeds, received from Mr. Hugh Cuming. It is very beautiful when 
in full flower, the large spreading panicle, with its profusion of blossoms of vari¬ 
ous shades of purple, contrasted with the dark green leaves and glossy stem, 
have a very pretty effect. Like the other variety, this is also perennial, and will 
doubtless succeed very well in the open border, during the summer months.—

Berberis buxifolia. —Box-leaved Berberry. This is a native of the straights 
of Magellan, and other southern parts of America, and has been lately introdn 
ced by Capt. King. It forms a low straggling shrub, and flowered with us in a 
cold frame; but in all probability it will prove quite hardy enough for our win¬ 
ters. It may be increased by cuttings or layers, and thrives in light loamy soil.

ericEjE. —The Heath Tribe. 
Erica quadrata. —The Square flowered Heath. A native of the Cape of 
Good Hope, introduced in 1829, by Mr. Lee. The flowers are white, very angu¬ 
lar in their form, and the opening perfectly four square, which has suggested its 
name. It requires the greenhouse, and may be increased by cuttings. The soil 
should be peat.— Bot. Cab. 
Rhododendron campanulatum. —Bell-flowered Rhododendron. This is a 
native of Nipal, and grows, as we are informed by Dr. Wallich, in elevated situ¬ 
ations, so that he had no doubt of its bearing our winters uninjured. This has 
been confirmed by actual experience, during the last two seasons, in which seve¬ 
ral plants remained with us perfectly well out of doors. The young leaves are 
at first purplish underneath ; they then become milk white, and afterwards, when 
quite hardened, change to a kind of tan colour. It may be propagated by layers 
and cuttings. The soil should be loam and peat.— Bot. Cab.
