This remarkable plant has lately been published in the Transactions 
of the Horticultural Society of London, whence the following account of 
it is extracted : — 5 £ 
** In the year 1834, John. Henry Lance, Esq. upon his return to England 
from Surinam, where he had been residing several years, brought with him a 
considerable collection of Orchideous Epiphytes, which he presented to the So- 
ciety. Among other interesting species was the subject of the following memo- 
randum; a plant, than which a more acceptable additiou to the hot-houses of 
this country has rarely been made. i u

particular O. flexuosum, bifolium, ampliatum and, crispum, but all these have 
flowers in which yellow or brown are the only colours, they owe their beauty to

house of the Messrs. Loddiges, and another shortly after in that of the Society. 
The plant was found by no means difficult to manage; and in point of beauty and 
fragrance it more than answered allthe expectations that had been entertained of
