if we were requested to select the most interesting from the multitude of vegetable tribes, we should, onthe whole, 
perhaps, be willing to give the preference to the natural order of Orcniprm. Whether we consider general elegance 
of individuals, durability of blossoms, splendid colours, delicious perfume, or extraordinary structure, it would be dif- 
ficult to select any order superior to Orchidez in these respects, and few even equal to them. To the cultivator, who 
-esteems plants for their beauty only ; to the botanist, who, rejecting outward attractions, is Onefly cantwated by ano- 
malous structure, or intricate organization ; or to the amateur, who wisely prefers to have these requisites combined ; 
to all, or any of these, we conceive that accurate figures of foreign Orchideous plants cannot fail to be particularly 
acceptable. | We therefore propose to publish one species of this family in each succeeding number; and we hope 
to be able soon to add such important information with respect to the treatment of Orchidew, as will entirely remove 
the present difficulty of cultivating them, and as may enable any one to manage them as readily as the most common 
plants of our hot-houses. 
: Weare obliged to Mr. Griffin for the communication of this very curious little parasitical plant, which flowered in 
his stove, last July, immediately after its arrival from Trinidad. 
It is perhaps of the same genus as some supposed species of Cranichis ; but does not appear to have been hitherto 
taken up by botanical writers. “It, however, differs from Cranichis, and from every other genus of the same section, 
in the characters we have assigned it above. | The curious manner in which the segments of the perianthium are 
united,—the two USED outer ones and (ne inferior outer and lateral inner. segments partially cohering in two divi- 
sions, which are themselves slightly connected towards their base,—is very remarkable. Something analogous 
takes place in Masdevalha, Restrephia, Pleurothallis, &c. which are otherwise very different. 
We have described the flowers as not resupinate ; agreeably to Mr. Browne very ingenious and correct idea, that 
the Labellum becomes the lowest segment in Orchis, Ophrys, &c., from a twist of the Ovarium, or of its stalk, and 
that, therefore, the flowers of those genera are in reality resupinate, properly speaking ; and not those which, like 
the present plant, have the Labellum above the Columna.
