We cannot say much as to the beauty of this plant, which 
flowered with Messrs. Loddiges in December 1842. It how- 
ever presents a remarkable instance of the formation of broad 
wings by the fruit, which, when ripe, has three of them of 
considerable size. 
The flowers are a brownish green, with a broad, rolled up 
yellow variegated lip whose middle lobe is whitish. It is a 
native of Mexico, and closely allied to E. tessellatum. 
Fig. 1. represents the column and lip.
