degree of heat; and also, by its sloping form, the more effec¬ 
tually to shoot off or discharge any redundancy of moisture, and 
to preserve the surface moderately dry. A thick covering of 
straw is also necessary, both to assist in preserving the gentle 
heat or warmth, and to defend the bed from excessive rains, as 
well as to exclude the external cold and damp.

OftCHiDEiE. —■ Gynandria Monandria. 
Warrea cyanea. This plant is remarkable for the intense porcelain blue 
colour of its lip, to which it is not easy to find a parallel in the order; for 
pure blue is scarcely known among Orchideas. The plant has quite the habit 
of W. tricolor, but is very much smaller in all its parts. Its most distinctive 
character is found in the form of the lip, which has a distinct point, and five 
ribs, not three, near the base. Messrs. Loddiges imported it from Columbia 
in 1843. —• Bot. Reg. 28-45. 
Stanhopea Bucephalus. This is one of the rarest and finest of Stanhopeas, 
in some measure resembling S. ocrdata, especially in the long, narrow 
hypochil. Its flowers are deliciously scented, and their bright golden colour 
produces a very rich effect. At first sight it might be mistaken for a variety 
of S. oculata, but the shortness of its ovary is a decisive mark of distinction. 
The effect of this shortness is to make the inflorescence of S. Bucephalus very 
narrow, while in S. oculata it is broad and straggling. The species is a 
native of the woods of Paccha, a small village in the Andes, on the ascent 
from Guazaquil to Loxa, at an elevation of 6000 feet, where it was found by 
Mr. Hartweg. — Bot. Reg. 24-45. 
Peristeria Humboldti var. fulva. A rich, tawny, yellow-coloured variety 
of the now pretty well-known P. Humboldti, which flowered in the collection 
of Mr. Barker, of Birmingham, in June, 1843. Its native country is 
Venezuela, where the original species was first detected by Humboldt. It 
is one of the most striking among Orchidaceous plants, and few are more 
worthy of cultivation ; the raceme is a foot and a half to two feet long, 
pendent from the. base of the pseudo-bulb ; the flowers are numerous, large, 
fleshy, of a tawny yellow colour, dashed almost all over with spots of purplish 
brown, and of an irregular globose form ; the colour of the lip is a brighter 
yellow than the rest of the flower, and the spots are deep purple. — Bot.

Angrcecum apicidatum. From Sierra Leone, introduced to our gardens by 
Mr. Whitfield in l844. 1 was at first disposed to consider it the same with 
A. bilobum, but that has semi-pellucid, reticulated leaves, distinctly and 
deeply two-lobed at the extremity; the rachis of the raceme and peduncle 
are warty, and the spur is dilated and emarginate at the apex, while in this 
plant the leaves are obliquely apiculate, opaque, and longitudinally striated, 
the rachis quite smooth, and the long filiform spur entire at the apex. In 
other respects the two plants seem almost entirely to agree. — Bot. Mag. 4159.
