Be 
ciles may be named I. pygmaea, thoush it is probable,that a lar- 
ger form of it exists.The leaves narrow a little toward the tips. 
and as with I,.lacustris the tissue is much coarser. In every 
way and using every method I looked in vain for it. The velunm 
is very small,enclosing hardly the rim of the sporangiums the 
macrospores are larger than with californica and have minute 
somewhat root-like elongated spiguless Neither species has 
lacustris.If this species were not such a small dwarf, I would 
have liked to name it forBolander. Ihhave not yet examined the 
other two species of the last letter, Isoetes lacustris and 
riparia from Massachusets, however I believe, that according 
to my last idea I riparia despite the stomata is in fact very 
close to I, lacustris, closer than I. Engelmanri I am not able 
of late to find any fibre-bundles,which seem to be constantly 
present in Engelmanni, at least in the forms which have been 
examined up to now. I am glad to know, that you sent some of 
the new Isoetes to Dorien; Hopefully he will be honest and 
not publish these species under other names: based on spore cha- 
racteristics? I have become careful with him, because he writes 
wonderful letters and promises much, but that is where it stops. 
I asked him repeatedly for a specimen of I. muricata I am still 
waitine for it, 
That my last letter was dated August 31 scares even myself. 
And so I have not written at all, that I spent several weeks 
with the family on Rügen and swam in the ocean still at the end 
of September and that I searched the chalkcliffs of Stebbenkan- 
mer without finding much, but these were beautiful days in free 
Nature, which I needed.
