Folia et pseudobulbi facie omnino O. papilionis. Scapus ascendens, radi- 
calis, 13-2-pedalis, apice ramosus. Flores lutei, labelli dorso albo. 
First found in central America by Mr. Cuming, and afterwards 
procured in a living state by Richard Harrison, Esq. from whom the 
beautiful specimen now figured was received in March last. 
Peculiar as are its flowers, and distinct as the species is in most 
respects, it is curious that its leaves and pseudo-bulbs should be so 
like those of O, Papilio, that we have known the latter to be mis- 
taken for it. 
Like all the rest of its genus, it requires the hot damp atmosphere 
of a Stove, in which, if we may judge by Mr. Harrison's specimens, it 
finds itself perfectly at home. We have not yet heard ofit in any 
other collection, ` 
It is well known that the most considerable part of the Epiphy- 
Jrchidez is found in the greatest vigour in damp sultry woc s of 
tropical countries; and accordingly we endeavour in our artificial 
cultivation, to form an atmosphere for them as nearly as possible that 
which they would naturally breathe in such stations. That this is 
attended with very great success is obvious from such plants as the 
One now figured, and from the numerous splendid specimens which 
are from time to time appearing in the collections of Earl Fitzwil- 
liam, Lord Grey of Groby, the Messrs. Harrison, Bateman, Huntley, 
Loddiges, and Knight, and the Horticultural re 
. „But it is sufficiently evident that although this ind of treatment 
is admirably suited to a considerable number, there are others which 
grow most unwillingly, or scarcely survive, under such circum- 
Stances. For instance, Dendrobium speciosum languishes in situations 
Where the Stanhopeas are in their greatest splendour ; and the Chinese 
Bletias almost perish by the side of Eulophia and Zygopetalum. This 
arises from the great difference in their respective eonstitutions, which
