Nothing new about Isoetesz;Robbins, the industrious collector,was 
sick or sickly almost the entire Summer and did nothing.Hwever Boott 
scouted his area well'and sent to me recently his loot from 48 diff- 
erent localitlies or collecting times,. New is I. lacustris from Can- 
bridge;form Boottlijthis vintage submergsed with very few stomata but 
with beautiful, delicate spines; muricata with only short spines; 
in form and habitus similar to the latter in the spore system from 
a new Llocality; Braunii from many localities, and ditto Tuckermani.

When l come in Spring 2 shall. bring a lot of this along. It is not 
difficult to find the stomata on the younger plants of Braunii,where 
the leaf-tips are well preserved;I also found them on muricata, but‘ 
searched in vain on a number of specimens, 
I have no idea if I mailed to you the sheets of the new Flora 
by Gray; Lemnae I have none, nor Callithriche, nor Sparganium, but 
Isoetes I send herewith. 
Mv bie job in connection with our moving,which must be firi- 
shed by March 1, is to censure the distribution of Junceus,the comple- 
tion of the printing-of the work on Juncus and Isoetes. There will be 
difficulties and time lost in packing and puttine away current itens. 
And that In Winter ! But may-be it could not be otherwise.- 
We probably will leave St. Louis during March and Awerica at the 
end of April or early May,and then straisht to Berlin ! Auf Wieder- 
sehen ! But I would like to have letters from you before that. 
A week back I wrote to Georg and tomorrow or the day after ıre 
expect to get letters from him; today I only send greetines to him 
and also a newspaper,. 
Greetings to all of you.I hear nothing of Caspari, and,obrious- 
ly he hears nothing from me. He could send me publications,which he 
certainly produces. But not now any more, I come myself,
