          N.S. while this seems a rare and little known Northern form. It was
decidedly subalpine in both the stations from which I have sent it. At the
White Mts. at an elevation of near (I should suppose) 2000 feet - + on the
Mansfield Mts. near a thousand feet higher. As remarked in your Flora [added: of V. edulus] -
it is a smaller and less straggling shrub than V. oxycoccus: which I di dnot
meet with till some time after leaving the immediate region of the Mts.
The large Xyris (X. caroliniana) grows only in the water, as is the case also with 
the Ceratoschoenus (C. macrostachys, var. of your letter) in Plymouth. I did not
observe anything to qualify these statements. Is not that Ceratochoenus a
very distinct looking form from C. macrostachys ? I see the nuts resemble each
other perfectly -  + of course I have no doubt the fact is as you have
decided: but I cannot but mention how striking the differences both of
habit and hbitat appeared. I hope you [crossed out: will not] do not consider me
as meddling rashly in these difficult questions.
I am very glad I sent you the tall Eleocharis that i labelled E.
tuberculosa. I put away that plant in my collection, with the smaller +
very very different true E. tuberculosa - with the sage commentary at
the bottom "Pl. variabilis:" supposing the differences were owing to immatureness
+ a richer soil! This I have amended now - + deposited the rare stranger
in its own paper. Finding this species at Plymouth, I brought it to Mr. Okaes,
+ asked him what this tall, wiry Eleocharis could be. He did not examine
it, but said he supposed it might be as above. He postpones examining
these plants tell the winter. I could an Eleocharis two years ago in
Cambridge, which I could not make out - that I think may prove to
be this species. It is now at Ipswich, with a few plants which I carried
down some time since - but I shall compare it with the Plymouth pl.
as soona s I can get it; and will inform you if it prooves to be the same. 
Though this i do not think more than possible. 
But I will tresspass no further with thie recital.
I ha not had the pleasure to recieve from you the Amer. Cyperaceae,
and I bought my copy (a dupl. of that no. of the Annals of the Lyceum)
of Mr. Warren our conchologist + virtuoso: who i understood recieved his set as 
well as this numbr from Dr. Jay of N.Y. Your kind offer of "a corrected
copy" including the Rhynosporae of Dr. Gray will be invalyable + I shall
be delighted to recieve it. If this is not contrary to your custom - I should
be greatly pleased with a word on the fly-leaf in memory of the donation.
