 minutely glandular. Upper corolla-lip with 3 rounded lobes, lower entire lanceo-

2. P. parviflorus, Benth. 



This plant, which is distinguished from the last by the much more slender spikes 

 and narrower bracts, occurs from Kumaon and Nepaul to Sikkim and Assam. It 

 may therefore possibly occur along our northern frontier especially in the 

 Champaran Hills. In the F.B.I, it is stated that it may be distinguished by never 

 being hoary as in £. plectmntJwides but the last is very frequently not at all hoary 

 in the field.
