122 DENDROBIUM AM PLUM. 
departs from the usual shape of those of Dendrohium, and exhibits an outline which 
to us seems most like that of a heart, with a particularly pointed extremity. This 
is, however, an insufficient deviation to raise it to the rank of a new genus, and it 
is therefore still assigned to Dendrobium. 
Messrs. Loddiges, in whose inexhaustible storehouse we were favoured with the 
opportunity of examining the specimen here depicted, imported the species from the 
East Indies a few years since, and succeeded in causing it to perfect its flowers in 
the month of October 1839. It was met with in great abundance on the Khoseea 
hills, by Mr. Gibson, His Grace the Duke of Devonshire's collector, and the paucity 
of plants in this country is consequently rather surprising. Probably, among the 
many packages which reach England from the Calcutta Botanic Garden, this will 
ultimately be more liberally introduced ; for in addition to the very remarkable 
novelties in its structure, it is both an interesting and ornamental epiphyte. 
As is customary with the members of this tribe, its mode of growth will dictate 
the manner in which it should be cultivated. At Messrs. Loddiges', the lower 
pseudo-bulbs are planted in pots, in a light heath soil, well blended with potsherds, 
and each stem or rhizoma is supported in a nearly erect posture by slender stakes. 
The nutriment thus derived from the earth, consisting chiefly of water and its con- 
stituents, is undoubtedly scanty, and the aerial roots must greatly assist in conserv- 
ing health, to which the moist atmosphere which these gentlemen keep essentially 
tends. In drier houses, it could be fastened to a block of wood, and each new 
development secured thereto, covering its roots with sphagnum moss. After 
flowering, it should be located in a dry situation for the winter, and again introduced 
to a hot humid house in spring. 
By tying a little moss round the roots of the upper and younger pseudo-bulbs, 
and slightly stimulating them for a short period, they will be rendered fit for 
detaching, and the rhizoma can afterwards be safely severed. In this case, the old 
lower bulbs that are left, will most likely put forth other new ones on being placed 
in a favourable atmosphere.
