(With Plate III). 



In the Calcutta herbarium there is an example of a very distinct 

 species of Nepeta which appears to be as yet undescrihed. As it has 

 been collected beyond the frontiers of India, it could not with propriety 

 be dealt with in the paper on Indian Lahiatce recently read before the 

 Society. But as it possesses rather more interest than isolated new 

 species usually do, its position in the arrangement of Oriental species 

 elaborated by the late M. Boissier in his work (Flora Orientalis, iv, 637- 

 670) dealing with the area in which it occurs, as well as a description 

 and figure of the specimen, are now presented.
