by candle light, dried on the backs of mules and some of them 

 packed for 6oo miles over the mountains subject to daily rains, 



I am preparing a rough sketch of my trip with the places vis- 

 ited to help the herbarium people in naming my collection. This 

 is not quite ready but when finished i will send it on in your 

 care. There need be no haste in delivering it. 



one word as to Umbel life rae- You seem not to have read my 

 last items on this family^ (" See Britton and Brown Vol. 2, 508, foot 

 note\ Thaspium trifoliatiom is the name to be used for this group 

 of species. i question whether aureum Bhould be used at all, but 

 if so it can be no more than a variety, but there is very poor 

 ground even for that as you will see from Dr. Brit ton's characterization. 

 Both forms of course should be included in your catalogue. T.bar- 

 binode ,you will of course admit. i suppose both Zizla aurea and 

 Zizia cordata will be included in your catalogue. 



Yours very truly.

Department of Botany.
