FLORICULTURAL NOTICES. 
of this gentleman in October 1840. The ordinary treatment of the genus is 
appropriate. Bot. Mag. 3886. 
Oncidium monoceras. Somewhat related to 0. raniferum and others, but 
having a stronger flower-spike, larger, furrowed, one-leaved pseudo-bulbs, and a 
singular little horn on the upper side of the labellum, " curved upwards, and 
almost as long as the lip itself." It has greenish sepals, yellowish petals, blotched 
with brown, and a deep yellow lip stained with red towards its base. " It was sent 
by Mr. Hunt from Rio Janeiro to His Grace the Duke of Bedford in September 
1839, and it flowered in great perfection in January of the following year." Bot. 
Mag. 3890. 
OxALis FRUTicosA. A curious instance of a shrubby species in a genus which, 
though extensive, is composed principally of herbaceous plants. The ordinary 
trifoliate character of the leaves in Oxalis is, moreover, seemingly departed from 
in this species ; but the three little leaflets sometimes seen at the extremities of 
what would be regarded as leaves are, in fact the true leaves, while the prominent, 
nerved, leaf-like expansions beneath them are only dilated petioles. It is an inter- 
esting shrub, bearing its pretty yellow flowers rather numerously in the axils of the 
foliage. Its native country is Rio Janeiro, and it has been cultivated successfully 
in the stove of His Grace the Duke of Northumberland. Its propagation is 
eff*ected by cuttings, or by a careful division of the roots. Bot. Reg. 41. 
Physianthus auricomus. The stems of this showy climber are densely covered 
with yellow hairs, whence its specific name. It is of a robust climbing habitude, 
with spacious hairy leaves, and numberless clusters of white, sweet-scented blossoms, 
wliich expand in succession, and are elevated on stiff peduncles, issuing from the 
axils of the leaves, or from the opposite side of the stem. Dr. Graham observes 
that he " first saw this handsome climber extending across the rafters from end to 
end of a stove in the garden at Hales, near Liverpool, the seat of — Blackburn, 
Esq., in October 1837- It was covered with blossom, each flower remaining long 
in perfection." The country it inhabits is not accurately known, but it is supposed 
to be from Brazil. Specimens planted in the border of a stove flower much finer 
than those grown in a pot. Bot. Mag. 3891. 
Salvia tubifera. A desirable acquisition from Mexico, where it was dis- 
covered by Mr. Hartweg, and transmitted to the Horticultural Society. It is 
now in most of the principal nurseries, and produces exceedingly long spikes of 
beautiful purplish flowers. Its habit is like that of the sufiruticose species. " It 
forms a busli about three feet high, branching and well covered with leaves, and at 
the end of every one of the branches there appear the long racemes of slender purple 
flowers, which are so disposed as to form a drooping or curving ornament. Like 
all the small-flowered Mexican kinds, it is not fit for planting in the open border 
during summer, as it only flowers at the latter part of the autumn, and in the 
winter months." A frame or greenhouse is consequently necessary for its culture, 
and it is multiplied by cuttings. Bot. Reg. 44.
