1888. During the whole of the investigation, too, Dr. King has taken the warmest 

 interest in its progress, giving the benefit of his advice at almost every step — much 



t the advantage of the enquiry itself. 



Mr. Duthik, Director of the Botanical Department of Northern India, very kindly 

 l>la< I tho material of the genus preserved in the Saharanpur Herbarium at my disposal 

 for purposes of study. Without this assistance the investigation of Western Himalayan 

 fonm must have been far less satisfactory. Dr. Garcke of Berlin, whom I consulted 

 regarding some species collected by Dr. Hoffnieister and described by Dr. Klotzsch, 



generously responded by sending authentic specimens of these to Calcutta. Mr. C. B. 

 Clarke with equal generosity sent specimens of the Pediculares of his Manipur journey, 

 while Dr. G. Watt kiudly volunteered the use of the material of the genus contained in 

 hU j)iiv;ito herbarium. 



I um moreover greatly indebted to Dr. Lange of Copenhagen, to Mr. Hemsley of 

 London, and to Dr. Trail of Aberdeen for being so good as to verify for me references 

 to works that could not be obtained in Calcutta. 



The assistance of all these gentlemen I desire gratefully to acknowledge.
