St. Louis Nov. 6,1866 
Dear Braun, 
Since Iwrote you a week ago and courageously enclosed living,;. 
wax-wrapped Isoetes, the eager and most obligring Boot rumased again 
through the Waters of his territory, or, rather, he waded throueh, 
of Isoetes 
and sent me 2 species gathered a week ago. One was a steril Isoetes. 
which is probably Engelmanni (stomata) from West Cambridge Brook, and 
numerous specimens of the pretty, fresh plant,which I recently recei- 
ved from Mystic Pond, and which I consider to be Tuckermani, this time 
from Hornpond. Unfortunately the season is too far advanced, so that 
frult formation is to be found only here and there... But the macrospores 
are beautifmlly marked, the covers with long lasts, the hemisphere 
with network. Sunday a friend of mine travels to New zores 5 ml} 
gibe him a small tinbox, in which both, but separate, are packed in 
moss and waxcovering; Tuckermani the small,numerous ones,Enrelmanni 
the long,green in few specimens. Further I added a large plant of Engel- 
manni(with cut-off leaves), which I received at the beeinning of Au- 
gust from Delaware and cultivated 3 inch below waterline; it's spores 
germinated in mass, and you will find many young plants in the mud, 
which surrounds the roots, if all goes well. 
Ihen I selected dried specimens of all the Isoetes received this 
Summer and packed them. You find there a lovely collection of riparia, 
Tuckermani,saccharata, valida, Engelmanni ,Braunii,melanospora,muricata; 
only macrospora,. Nutalli and florida are missing,which I do not DOSSeSss 
myself. You will have fun with the material, and it will with what I 
sent you durinr the Summer give you abundand material for studies, 
Kopefully you can find the time to get to it, 
I took advantage of the kindness ofDr. Buchanan in DSremen,to 
transmit these items all to you, as I do not know,if they can get to 
you directly without customsproblems and delays. I hear, that the 
package,which you sent to me has arrived in Washingtom, and hope to
