Möst Honored Friendr ! 



IT carae yesterday into possession of your letter of Augp. 17 

 and its most interestlng enclosure (it seems to be of the first Or- 

 der) ; I hurry, to thank you for both^.I am very glad, to hear a few 

 words from you^after your son has left Tubingen since two weeks, as 

 you will have heard from him directly, and , aecording to news from» 

 there, has moved to Kreuznach, the seat of a military hospitall* 



As to the Spirodela ,it is highly welcome, because it is not 

 entirely new to nie, but the present see ^ßte will serve rae well!.About 

 6 days ago came a letter, dated Aug. 12 from Mi*. Leggettt fronr Funcha 

 (??? E.D. ) ,containing a number of floweringr fronds^but only 2 Or 3 

 fruit, which can be examined. The smallness of the plantles is either- 

 entirely accidentali or, more likely, is connected" to their fertility,. 

 Negative is, that there is no dif^erence to be found from our polyv - 

 rrhiza . However, the most striking is not only - as Mr.Leggett al - 



| ready stated in the letter - that the fruits are one-seeded^but also 



- I found this without exception on a number of flowers - that the 

 | to 

 5 ovary is uni-ovulate, it^trends in its anatropi sra fthe very similar 



"crO Ovulum of gibba , the seed though positions itself (( as with gibba , 



^ when through a mlss"*it becomes one-seeded) through shrinking of the 



hilum and partum (??? E.D..) almost to the length-diameter of the 



fruit, where it comes to lie as in minor« . As the proofs for feteg our 

 ~ polyrrhiza definitely come out for two, and as an observer as con- 



scientious as Grif f ith has given a harmonizing picture, it seems too 



mustbe considered 

 me already for that reasorr.that the form from™ New YorkTat least as 



a new sub-species', if not species.even if other differencesr in the 



sphere of fruit formation sgould not exist,for x^hich I cannotf judge 



as I have ssen the old-world form only sterile. Equally,©^ are na- 



turally not capable to decide.if ( / which is not at all! probable)'
