This plant is described as being scarcely 8 inches in height 

 with a fusiform root : its leaves^ sometimes geminate^ are from li 

 to 1| inch long, and 1 to 1^ inch broad^ upon a petiole 9 to 10 

 lines in length : the peduncle of its solitary axile flower is half an 

 inct long, its calycine segments 6 lines, the tube of its corolla 

 10 linesj the lobes of its border 7 lines and 31 lines broad.

. Although found near the same locality, and in no way diflfer- 

 ing in the shape of its leaves, its herbaceous stem and tapering 

 root, this plant offers many points of structure at variance with 

 the foregoing species, if we depend upon the usually accurate 

 descriptions of Prof. Kunth. It is double its height, and its 

 leaves are proportionally larger, being often geminate, 2| inches 

 long, 2 inches broad, upon a petiole f inch in length ; the pedun- 

 cle of its axillary flower is 1 inch long, its narrow linear acute 

 calycine segments are 1 to f inch, the tube of its corolla 1 inch to 

 1;^ inch in length, and 2 to 3 lines in diameter at the mouth ; the 

 lobes of its border are lanceolate, oblong, very patent, and ^ mch 

 long ; the corona, with ten obsolete teeth, protrudes'2 lines be- 

 yond the throat; the stamens, inserted somewhat above the middle 

 of the tube, are 3 hnes long ; the ovarium is elongated and point- 

 edly conical, 3 lines long, f line at base, and is seated on a pro-
