Brazil. A fine species, with the sepals blotched with chocolate brown 
upon a yellow ground. Lip white at the tip, violet-coloured at the base. 
Now that the true limits of the genera allied to Brassia are better under- 
stood, this plant it is hoped will rest without further change. It is 
evidently a transition from Brassia to Miltonia ; but upon the whole is 
better placed in the former than the latter genus, on account of its 
column having no trace of wings. 
14. MAXILLARIA corrugata. 
M. corrugata ; pseudobulbis ovatis subimbricatis, foliis lanceolatis solitariis 
breviter petiolatis, racemis paucifloris petiolo multo longioribus, bracteis 
minimis, sepalis petalisque obtusiusculis, labello oblongo utrinque emar- 
ginato (ideoque obsoleté trilobo) venis elevatis flexuosis corrugato, tuber- 
culo mediano obtusé tricarinato. 
This plant, belonging to the same division of Maxillaria 
as M. squalens, was found by Linden between Maracaibo and 
Bogota, and has just flowered in Mr. Barker's collection. It 
has pale brownish purple flowers of no beauty; and alip with 
numerous purple elevated zigzag veins on a pale yellow 
ground. "The long tubercle in the middle, which in these 
plants is usually undivided, or merely 3-lobed at the ex- 
tremity, is here broken up into 3 distinct contiguous elevated 
ribs. 
15. ZYGOPETALUM. 
This genus, founded by Sir W. Hooker on the Z. Mac£aii, 
is extremely near Eulophia, from which it principally differs 
in having a deep ridge or bridge lying across the labellum 
near the base. The union of the sepals and petals, from 
which the name is derived, is too inconsiderable to merit atten- 
tion, and is not constant among the species now known. The 
presence of blue, or some marked shade of that colour, upon 
the labellum, is another characteristic feature, by which the 
genus is to be distinguished from Eulophia, in which that tint 
is, as far as I am aware, unknown. 
In consequence of the additions that have been of late 
years made to the genus, all of which, with one exception, are 
aan il
