 and the calli are wliite ; in tonientosa ihe flowers are smaller , as well as panicled,

6. lONOPSIS PULCHELLA II. B. K., Nov. Gen. et Sp., pl. L. 348, t. 83. L. 0. 194. L. f. 7: 

 I. foliis lanceolato-linearibus acutis planis coriaceis basi carinatis, 



scapo subsimplici , sepaiis lanceolalis acuminatis patulis, petalis duplo 

 majoribus oblusis, labeili limbo obcordato sepalis multo longiore, auri- 

 culis rolundatis, sacco simplicl. 



Of ihis I have seen no certain specimen. It appears to differ from L tenera in 

 having rauch narrower smaller leaves, and a larger lip, wilh long obtuse petals. The 

 leaves, according to Kuntli. are from two lo tliree inches long , and not more ihan 

 three lines broad. I now refer ihe Cuban plant of Liuden („Orch. Lind.", Nr. 125) 

 to tenera. An examinaiion of original specimens can alone deiermine whelber tbe 

 iwo are realiy disiinct. 



Wild in New-Granada; in warm temperate places between Carthagena and Buga, 

 on the trunks of Guava and Calabash trees , al ihe height of 2928 feet , flowering in 

 Octobcr Huniboldt and Bonpland.

A much smaller-flowered plant, ihan I. paniculata , which it resembles , with v^ry 



sharp insUad of obtuse peials. The auricles of ihe lip are not rounded, but broader 



in front so as to resemble a blunl-angled wedge but in half.
