not be averse; but, as you know, , my wishes are so far modest 



ones.I fear, that the plant, which is sterile with you, does not 



exist any more af ter** its habitat has been dried out f . and that thus, 



I cannot get it from you any nore,. Mäy-be I will be successful in 



Melbourne, where I write for Azolla pienata (?? E.D. ) (which belongs 



into another section than caroliniana )• I do not like to let go of 



such a small project once I have got it into my head..

You write, that you did not receive the/theme about Lemna e ; of 

 course, because it does not exist yet. But I will return to this sub- 

 ject without fail'as soon as the nearest-lying has been pushed off.. 

 For the cause itself it will only be of advantage, if it rests a 

 little while, as from time to time contributions arrive, which can 

 be evaluated . Thus I found recently a striking form from Brazil 

 (belonging to abbreviata ) with a few flowers,, the only ones so far 

 besides the flowering Lemna Torryl ; fruits I do not find..I will have 

 to write once more about this family, already because the geographica! 

 material has become much richer in the meantime, , and which must be 

 combined from notations collected so far. Recently came also fi - 

 nally a Lemna from Buenos Aires, and most suprisingly gibba , with 

 the remark by the sender, Prof. Burraeister, that this was the only 

 form found in the lowlands there, , which may be questioned, The pre- 

 sence of floxrers and half-ripe fruits with 3-4 embryonic seeds 

 finalljr determine the identity of the americair gibba with the euro- 

 paean* entirely«. - Strange is also a lemna, discovered quite some time 

 back by S. Kurz in in Erast A^la , and, according to his message, quite 

 rare there and since unknown v ( Lemna Kurz ) . . T sacrif iceJt a few of the 

 few received frondesf for examination-,and it seems, that finally a
