Orciiidace^. —Gynandria Monandria. 
Oncidium spilopterum (Lindley). This beautiful species was 
introduced by Messrs. Loddiges, from Mexico, in 1844. The 
flower-scape contains seven to ten flowers; the sepals small, 
ovate, acute, free, of a purplish-red, with darker spots; petals 
the same as the sepals ; the labellum large ; three-lobed, almost 
round; two lateral lobes small; middle lobe purple, red at the 
base, the broad spreading part clear yellow ; column crenulated, 
somewhat heart-shaped, clear yellow, spotted with purple-red.—

LeguminosjE. —Decandria Monoyynia. 
Burtonia villosa (Meisn.) A small, heath-like shrub, with the 
leaves horizontally patent, and, as well as the branches, clothed 
more or less copiously with hairs ; leaflets linear, obtuse, appear¬ 
ing to be terete, from the closely re volute margins. Flowers 
numerous, from the axils of the leaves, at the extremity of the 
branches, and forming apparently an oblong leafy spike, the 
leaves and peduncles being in a great measure concealed by the 
flowers. The short peduncle supports a hairy calyx, the tube of 
which is campanulate; the five spreading, nearly equal lobes, 
ovate, acute. Corolla rich purple, but less deep than B. pulchella. 
The wings whitish at the base, and the standard with a nearly 
orbicular, pale yellow spot above the short claw. Recently 
raised from Mr. Drummond’s Swan River seeds, by Messrs. 
Lucombe, Pince, and Co., of Exeter.— Bot. May. 4410. 
AcanthacEjE. —Didynamia Anyiospermia. 
Thunberyia ay,rantiaca JDoddsii. A variety of the well-known 
summer-flowering climber, Th. aurantiaca , distinguished from 
its parent by the variegated leaves. The flowers are the same in 
size and colour, but the foliage is irregularly margined with 
white. It was raised in 1847 by Mr. Dodds, gardener to Colonel 
Barker, of Salisbury. The most expressive name would have 
been Thunberyia aurantiaca varieyata; but as the plant has 
become known in nurseries by the name of T. Doddsii, and we 
are unwilling to deprive a persevering man of any portion of the
