Dear Dr. Robinson;- 
I have not authentic collections here that warrant 
me in supposing tha,t I can name without too much waste 
of time any of the Loranthaceae except Phoradendron . 
Of course I shall be more than pleased to look over any 
thing in that genus - even if uniques that you want re- 
turned . 
Just now I am trying to round up Piper, north of the 
Isthmus. Ultimately it is probable that I shall go over 
the South American species; but as yet there are very 
few of them that I should care to name. 
Unfortunately I do not know of any one who would do 
adequate vrork in either group. 
Probably you have none of my friends in Liliaceae or 
Amaryllidaceae , but if you have I could attend to them 
promptly . 
Sincerely yours.
