St. Louis, May 18, 1867 
Dear Braun 
That was again, just like the last one, a trWly long letter, 
which I received on the 15th. Si®e then you too rechhved one from 
me with the Isoetes Cubana and the questionable from Cap (leaf). 
I told vou already, that in Grayv's herbarium a second Cap exists; 
also, that the very delicate leaf seems to have a unlaue struc- 
ture; I do not believe that it belones to setacea,. 
I further enclose Isoetes califorrica, which I received in 
a letter with pygmaea in a few specimens; I do not know if the 
promised box, which is supposed to bring primarly Juncus from 
California contains also Isoetes. It was supposed to be shipped 
at the beesinnine of February, as Bolander writes, and contains al- 
so Liverworth, it should have been here long ago. This delay has 
also restricted my work about rushes, respectively it's comrle - 
tion, as I wanted to include the expected material. In another way 
it has helped me, 1.e. the completgion of paper on rushes, as I 
finally received now material from Michaux and others from Paris. 
However, I may have told you of this earlier. 
Now to Isotes. It was entirely new to me, that you want to 
publish already now; and I fear, that we will get into each other's 
territory. However, as neither of us has printed anything so far, 
no damage has occured. Only for the new edition of Gray's dia I 
treat the Isotes, as I had written to you. Needless to say, that 
I considered your studies fully in this undertaking. I had decided 
to publish my results of our transactions right after finishing 
with the rushes, as I had found so much new and interesting in the 
Isoetes,. I hardiy know,, if this will happen now, that you plan to 
publish a detailed opus,which contains also all my observations 
and discoveries, making mine superfluous; I would have prefered, if 
the local wotk had appeared first, and your more thofovueh and en-
