lobe very large, contracted, purple, and crested with irregular 
lamellae, then expanded, and purely white.— Bot. Mag. 4272. 
Coelogyne ochracea (Lindley). A species with moderately 
large, pure white flowers, having bright orange-yellow blotches 
on the lip: they are very pretty, and are moreover extremely 
sweet scented. We possess the plant from several localities 
among the late Mr. Griffiths’s valuable Indian collection. Dar¬ 
jeeling, Bootan, and the Mishmee hills all produce it. These 
specimens differ a little among each other in regard to the 
amount of toothing present at the sinus of the lip, and as to its 
exact form, but they all belong evidently to the same species.-—

Hoy a imperialis (Lindley). This is the most noble climbing 
plant we have ever seen. Beautiful specimens in flower have for 
some months been in our possession, sent from Borneo by Mr. 
Lowe, jun.; but we have refrained from publishing an account 
of them, under the supposition that no living plant had reached 
England. We are now, however, able to state that the plant is 
in the possession of Mr. Lowe, of Clapton, who has already begun 
to put it into the trade. Imagine, then, a true Hoya, with woolly 
stems, leaves six inches long, and clusters of the most magni¬ 
ficent flowers, forming a diadem of ten rays, each flower fully 
three inches in diameter, and with the delicate texture of the 
common Hoya carnosa. In Mr. Lowe’s letter from Sarawak, 
dated January 12, 1846, we have the following account of its 
discovery :—“ On the next day, when in the territory of the 
Gumbaing Dyaks, I found another curious plant, belonging to 
Asclepiads ; it is an epiphytal climber. There was but one indi¬ 
vidual, growing from the decayed part of a tree, also overhanging 
the river. The flowers are large and in umbels ; the leaves are 
leathery; and the stem abounds in a white, perhaps acrid juice. 
The contrast between the purple of the petals and the ivory 
white of the parts of fructification renders it highly beautiful.”

Xiphidium giganteum (Lindley). This is a large iris-like 
plant, with leaves more than two feet long and two and a half 
inches broad. When in flower it is nearly four feet high. The
