In the small island of Fernando, and on the celebrated "peak" 

 there, at altitudes varying from two thousand to five thousand 

 feet, the enterprising botanical traveller, Mr. Gustav Mann, de- 

 tected four new species of Balsam, which have been described 

 by Dr. Hooker, in the journal above quoted. The present is 

 one of them, of which seeds were sent to Kew, and which 

 flowered in December of 18C2, the same period of the year 

 when Mr. Mann obtained flowering specimens on its native 

 mountain, in I860. These were gathered at the altitude of 

 four thousand feet. The flowers are remarkable for the pure 

 white at the mouth, and the full purple colour of the labellum.

 a few scattered, short setae appear on the petioles, and a soli-
