Mr ,Wa It er Dea ne , 



Cambridge, Mass. 

 My dear Deane : 



Your card of the 19th. and letter of the 22nd. are 

 at hand. Let me thank you in advance for the San Antonio plants. 

 Everything like this is welcome in a great herbarium like ours. 

 As to your inquiry about Thaspium aureum I can not answer definite- 

 ly. The ranges in our Monograph were worked out by Professor 



rr * 



Coulter^ while the specimens examined are those that passed 



through my hands. Whether he quots from the Gray's Manual or 

 Britton I am not quite certain but perhaps more properly from our 

 Revision^ but whether from the Manual or the Revision it makes 

 little difference as both are the handiwork of Professor Coulter. 

 I think you can very properly exclude this species from New Eng- 

 land. 



Yours very truly, 



Assistant Curator, 



Division ofPlants.
