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 havinff no trace of wings. 



14. MAXILLARIA conugata. 



M. cornigata ; pseudobulbis ovatis subimbricatis, foliis lanceolatis solitariis 

 bi'eviter petiolatis, racemis paucifloris petiolo multo longioribus, bracteis 

 minimis, sepalis petalisque obtusiusculis, labello oblongo utrinque emar- 

 ginato (ideoque obsolete trilobo) venis elevatis flexuosis corrugate, tuber- 

 culo mediano obtuse 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 a lip with 

 numerous purple elevated zigzag veins on a pale yellow 

 ^ound. 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. Mackaiif 

 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
