Dear Doctor 



You sent me in the suaaer soiae Isoetee whioh I 



have identifled as X.melanopoda with large spores. After repeated 

 investlgatlons I have to oonslder 1t aa I.Butleri t whleh I know from 

 the Indian Territory and which at one time I publlshed in the Botan- 

 loal Gasette. However,lt haa several oharaoters whloh I would like 

 to study thoroughly. If you perhaps have more speolmens on hand, e spec- 

 ial ly older and more mature ones,I would appreolate very auch havlng 

 the«, for.I am Just now oocupled with an extensive paper on the North 

 Amerioan Isoeteß, which Z would like to coraplete. 



Have you perhaps colleoted this plant again laterjlt would be very 

 desirabie to me» Let me know the detalls of the habltats wet, humid t 

 dry etc., and assoclated plant 0. 



In the summer % was in the Rocky Mountains for a change.and in a 

 Lake at the sources of the Colorado I walked on a lawn f ormed entir- 

 ely of Isoetes laoustrls» three feet below the water, whlch until then 

 had not been met with in the West. I am sorry to say that the plant« 

 were not fully matured than. 



Besides I have brought with me several nice things and I shall be 

 pleased to inolude you f to whom I am so mu oh indebted, when the question 

 of the dlstrlbutlon will oome up. 



Sinoere greetlngs 



yours
