Now I want to tell you most of all,that all your shipments 
have arrived and I want to thank you for the fine and ample speci- 
mens. The bundles for salt-treatment (this translation is a guess on 
my part as Il cannot decipher 2 words.E.D.) were of course entirely 
dry, so that I did not select them for examination,however I have 
s number of live sperimens: Engelm.melanopoda "Braunii", Tuckermanri. 
From Brott I received a tiny box with live species: Braunii ,Tucker- 
manni and a form, which Brott calls muricata, which I however based 
on the spores had to call Engselmanni. The shipment arrtved in late 
NoveMber and all the outer, fertil leaves had rottedAnd only weak, 
sterile leaf-bundles were present,but there were spores everywhere 
between the dead material. This shipment was very impolftant to me for 
the examination of the leaves. I report today about several species. 
I. muricata I distinguish from "Braunii" for the short, bumpy 
spores, the very dark-green leaves,rich in chlorophyll but with thin 
edzges,which are totally without stomata.You write,that they have sto- 
mata at times, but put them in an earlier classification with the 
species that have no stomata.I determine from this, that you con- 
bine a form which I separate.I refer to the one collected by Boott 
"in a shallow pond without outlet in Woburn,Mass." specimen wholly 
submerged. 18. Sept.1866 (remark on side of sheet: namely in rela- 
tion to stomata ).This form has long spinules (Braun calls them 
"spines"- Stacheln) at the tips, just like echinospora, but plenty 
of stomata, a deeply descending velum. I call it in the meantime 
I. Boottiil,as,thoush closely related to Braunii from Woburn, she (#2) 
is not identical,because Braunii has certainly only very few stomata.. 
I did not find any on the live form sent from Mystic Pond. I have 
not had the time to examine those, which I believe to be echino-
