study, regarding which I will again send you more details. I am also diligently 

 studying teratology and flower morphology, and it is quite possible that before 

 long I will publish a compilation of teratology, which could be better than that 

 of M. T. Masters« That in addition I will carry on studies about fungi, I hope 

 also to show you very soon. 



The old Röper - it occurs to me - whom you probably also knew, is enjoying, 

 apart from his being hard of hearing, a very vigorous old age and has retained 

 a lively interest for morphologie. That he is not always in agreement with the 

 newer raorphology you will comprehend. 



With best greetings, 



Your devot ed

Brauns manuscripts were purchased by the Academy. Part of them are to be 

 published 



All of the vascular cryptograms will fall to Max Kuhn. However he will 

 only work them up systematically and probably not very thoroughly. I believe 



that you will work on the Isoetes; S ; Several years ago I once searched 



out the large work of your reports about Isoetes species to Braun from the 

 manuscripts of Braun, from which I learned your unusually exact studies of 

 them. You appear to be the best qualified to do this. 



I have also taken over after Braun and my own studies to work on the 

 morphological structure of the species Segonella.
