* Pyrv^ haccata, y himalaica Maximowicz in Bull. Acad. Set. St. Pelersbourg, 

 XIX. 171 (1873) is based on specimens from Gurhwal, which are near typical M. 

 haccata. They are different from the plants of the Khasia Hilla, which belong to 

 Af . theifera; to the same species probably belong the specimens from Sikkim and 

 other parts of the eastern Himalaya.
