little point. PoLLEN Masses two, small, pear-shaped, furrowed at the 
back, inserted on a wedge-shaped caudicle, with a very small oval 
gland. 
PoruLaR AND GEOGRAPHICAL Notice. This genus consists but 
of this single Mexican’ species, of which the habits are as yet scarcely 
known. It appears, however, to be terrestrial, and to grow in that 
tierra caliente, which, with Demerara and tropical Brazil, is now 
supplying our stoves with innumerable novelties in the inexhaustible 
tribe of Orchidacez. To such a degree, indeed, has the zeal for col- 
lecting these interesting plants been carried, that notwithstanding the 
difficulties attending their cultivation, till lately considered as almost 
insurmountable, the number of species contained in the stoves of 
Messrs. Loddiges & Son, according to their last catalogue is 1024, being 
nearly three times the amount of the total number, including Euro- 
pean ones, contained in Persoon’s Synopsis, published in 1807, when 
there were not above two or three dozen in garden lists, and scarcely 
half a dozen in cultivation. 
INTRODUCTION; WHERE GROWN; CULTURE. First introduced from 
Mexico, in 1835, by George Barker, Esq. of Springfield, near Bir- 
mingham; this rare and curious plant has since spread into a few of 
our principal collections. Our drawing was made in winter, at the 
Messrs. Loddiges’, where it thrives under the same treatment as Max- 
illaria, its nearest allied genus. 
It cannot be too frequently noticed that in potting orchidaceous 
plants every available means should be employed to insure the most 
perfect drainage. We have not yet seen such as we conceive would be 
the best. pots for the purpose. They may be made without bottoms, 
with a simple rim projecting outwards at the bottom, as a flange, 
nearly corresponding with that usually worked round the top: This 
would give the required strength. A number of little basons, of differ- 
ent sizes, made of the same material as the pot, and perforated all over 
with holes, a quarter of an inch diameter, would form suitable bottoms. 
These should be put into the pots with their convex sides upwards ; and 
the conical shape of the pots would admit of these moveable bottoms 
lodging against their sides at a higher or lower point, according to the 
size of the bottom chosen, so as to suit the wishes of the cultivator.
