 Dr, Engelmann of Oct. 3, 186?: E.D.. 



Hepa*ted exaraination-lets me come to the result, that f your 



Wolf f ia from Detroit can not be separat eäc from brasiliensis , the 



differences in dimensions are on average not as great as T thought 



in the beginning'; remains thus onl^he larger quantity^ of pigment 



as with the^riginal plant of Widdelli, which I consider ve^y insig- 



nificant as a characteristic. 



Of the saraples from Orange County from Mr. Austin I have sear- 

 ched in vain until now for this type, may-be I will find her still,, 

 when I soak the entire suppljr and make use of it. It seems to be 

 rarer than W. columbianum . What you send me from St. Louis is how- 

 ever identical with the plantlets from Orange CountyThe two Wolf f ia s 

 fruiting in South America, are probably found onljr 7 sterile with 

 you (at least in the northern states 4 ) i W. arrhiza behaves in the 

 6ld Vorld in a quite analogous way. . 



(Meeting you with highest esteem, Your

I think, at most one could separate your Wolffia as a variety 

 from the typical brasiliensis
