31. Epidendrum (JEuepidendrum) piperinum ; caule ramuloso, foliis 

 distichis succulentis oblongis obliquis obtusis laxe vaginatis, pe- 

 dunculis brevissimis terminalibus subbifloris, sepalo dorsali peta- 

 lisque filiformibus erectis laterahbus ovato-lanceolatis carinatis 

 horizontahbus, labello ovate cochleato ecalloso venis radiantibus 

 in margine confluentibus. 



Quito (Hartweg). 



A small succulent species, when dried beautifully netted. It looks 

 like a Peperomia. 



32. Epidendrum (Euepidendrum) orgyale ; caule orgyali distiche 

 foliato, foliis ovato-oblongis margine vaginisque scabris, racemo 

 sessili erecto cylindraceo bracteis membranaceis subulatis, floribus 

 carnosis, sepalis ovalibus, petalis spathulato-linearibus serrulatis, 

 labello cordato serrulato callis duobus juxta basin unoque sulcato 

 minore sub apice. 



Near Santa F^ de Bogota (Hartweg). 



Stem 5 feet high. Flowers apparently yellow. The fistula of the 

 ovary inflated. 



33. MicROSTYLis tipuloides ; foliis pluribus radicalibus obovato-lan- 

 ceolatis, racemo longissimo laxo, petalis filiformibus reflexis, la- 

 bello multo majore ovato-lanceolato ciliato. 



Popayan (Hartweg). 



34. Odontoglossum revolutum ; foliis ensiformibus rigidis margine 

 revolutis scapo rigido apice paniculato brevioribus, bracteis laxis 

 acutis cucullatis, panicula subcorymbosa densa, sepalis petalisque 

 lanceolatis unguiculatis acutis, labello conformi sessili cordato la- 

 mellis 5 carnosis integris quarum tres superiores multo breviores : 

 lateralibus subulatis, columna aptera. 



Popayan (Hartweg). 

 Scape above 2 feet long. 



35. Odontoglossum crispum ; foliis lanceolatis scapo multifloro 

 paniculato (nunc brevi racemoso) brevioribus, sepalis ovato-lan- 

 ceolatis, petalis ovatis acutissimis crispis membranaceis, labello 

 subconformi dentibus duobus validis in fronte paucisque mino- 

 ribus utrinque versus laminae basin, columnse alis rotundatis 

 laceris. 



Bogota (Hartweg). 



A most beautiful species, occasionally as much as 3 feet high and 

 more. Flowers large, yellow, with a purple centre. 



36 . Masdevallia racemosa ; caulescens, folio coriaceo lanceolato
