My dear Dr. Robinson: 
I shall be very glad Indeed to Identify 
Professor Hitchcock’s specimens of Vernonia and Elephant opus . 
I should also like to look at his collections in the family 
Lobeliaceae. I have been engaged with these plants for two 
or three months past and find it very difficult to make any 
progress, northern South America seems to be full of new species 
in this family, of twenty-four sheets sent to England with Dr. 
Britton, not one can be matched with anything in the Kew Herbarium. 
It is doubtful, therefore, whether I can identify all of his 
lobeliads but I would at least do the best i could. 
Very truly yours 
Acting Director
