It is not easy to tix upon the section of the genua to which this pretty and well-marked 

 species should be referred. The discoverer not unnaturally took the plant for a Ci'mx/in, not- 

 withstanding the size of the blossom ; hut the stout style is persistent on the capsule and splits 

 through in dehiscence, and all the characters are those of a Gentian. The slender stems are 



always simple, and hear from two to tour pairs oi small leaves, the uppermost remote from the 



solitary flower. The showy eorolla is fully an inch Long, and of a brighl blue color. The 

 stigmas are large and broad ; the ovary tapers below into a decided Btipe, which in fruit 18 half 

 the length of the oblong eapsule: and the seeds are broadly winged ; their insertion sutural.
