lets one guess at alraost anything but the plant in question, 



(were it not for the several Originals distrlbuted in herba^ia) as 



which I mention it in the beginning, though I am less than convin- 



ced ; about her identity but lelieve, that a definitive 



perhaps 



species is involved, which/ may become known only after an inspec- 

 tion of flowers and fruits. In the Berlin herbarium is L, minima 

 Phil, and L. valdiviana , Phil ; of the latter I enclose an orignal 

 sample for you. Some northern numbers (from California by Bolanden) 

 stand in a way in the raiddle. however, these sterile ones can bring 

 one almost to desp&ration ; any firm ground is missing.and yet, Ii 

 am glad to get again and again such forms for examination.. Thus, I 

 believe to be able to distinguish L. perpusilla and paucirostata 

 sterile by their root-divi sion ( this could be l, root-disk ,, f 

 German either Scheide or Scheibe ,E. D. . ??) . 



Prof, Braun has a very charming Lemna in his herbarium, -which 

 I have named a sterile Wolf f ia lingulata . The W. oblonga ( Lemna 

 oblonga Phil • ) , enclosed for you f ,is her closest known relative, she 

 is distinguished from the real Wolf f lae in very important way, 

 (a dissertation herk would^/boo far) is up to now known only sterile,, 

 but offers vegitatively outstanding forms. Her addition to Wolffia 

 can only have preliminary worth, and cannot be predicted fe£ some- 

 time fruits will be discovered.. 



If the magnificent and valuable collection of Junen s be re- 

 ally destined for me, I" would not know, how I could prove my grati- 

 tude for it now*. 



The seeds of L. perpusilla , sown this spring, did not germi- 

 nate, but perished unf ortunately.

 collections, and would in not be possible.to obtain from hiirr through
