rente Brazil. Very near E. elongatum, from 



which it differs in its elliptical blunt succulent leaves, 

 small middle segment of the labellum, paler flowers, and 

 especially in the form of the tubercle, which is deeply 

 furrowed, or plaited, and shoulders off to the lateral lobe's 

 of the lip, and is not furnished there with a free tubercle 

 as in E. elongatum. Flowers light rose colour.

L. no. 53.) ; foliis distichis oblongis obtusis tarnosis,

— — Pe7'u A very fine species, with orange-coloured 



flowers. The leaves are an inch and a quarter broad, 

 and the stems as thick as a swan's quill, and apparently 

 often branched. When old they become as smooth as 

 bamboo. (Not in cultivation.) 



15. E. cochlid'ium (Lindl. in Ann. Nat. Hist. vol. 4.) ; foliis 

 distichis ovato-oblongis obtusis emarginatisque coriaceis, 

 sepalis petalisque lineari-lanceolatis patentibus a3quali- 

 bus, labelli laciniis laceris subsequalibus callo carnoso 



maximo excavato trilobo parum majoribus Peru. 



Only known from a specimen found by Mathews in 



Peru. The flowers seem to be yellow. The very large 

 tubercle which covers the whole centre of the lip is very 

 remarkable. (Not in cultivation.) 



10. E. dichotomum (Presl. Rel. Hsenk. 101. L. no. 58.) ; 

 foliis distichis lanceolato-oblongis obtusis, caule apice 

 aphyllo squamoso ramoso, sepalis petalisque lanceolatis 

 acutis reflexis, labelli tripartiti laciniis fimbriatis : late- 

 ralibus rotundatis patentissimis intermedia majore obcor- 

 data, callo concavo crenulato indiviso tuberculis 2 prope 



basin Peru. A very fine species with yellowish ? 



flowers, which are perhaps the largest of any in this 

 section. Mathews found it in Peru, and it is no. 1024 

 of his collections. The unlobed tubercle, with a pair of 

 calli near its base, aflbrds a good mark of distinction. 

 (Not in cultivation.)
