          In other words of about 113 or 114 N. American species, I want
specimens of about 70 even although I exclude many of Brown's
Artic [Arctic] ones which altho' I have not, I have designedly omitted.
But this enumeration of my wants of [crossed out: Cyperaceae] [added: Carices] will show 
you in a manner what I want of other orders, for I presume all
the others are deficient in a like proportion. Some of these
Carices I have from [?] but I wish to have N. American specimens.
Others are published in Dr. A. [Asa] Gray's work, but I do not consider
that I possess any one till it is bona fide lodged in my herbm [herbarium].
Dr. Gray's specimens are valuable, but they are not part of my
herbarium, nor do I choose to hurt them by dissections.

By the bye tell Dr. Gray that I have named a new genus
of Ceylonese [crossed out: Cyperaceae] [added: Gramineae] after him, Graya, which I have no
doubt but Nees v. [von] Esenbeck will acknowledge. I hope to be 
able to send you specimens: it resemble a Rottboellia, but has
awns. I hope therefore, until the fate of this genus is known, that
no one will dedicate a genus to him; the more so as I trust that
the genus is a most distinct one, and secondly because it belongs
to the favourite tribe of Dr Gray's.

I see that I have  omitted to say that Scirp. [Scirpus] subsquarrosus
of Gray, which I have from Drummond from St. Louis, appears identical
with what I have in my herbarium as Scirpus micranthus Vahl (the specim [specimen] 
I believe from Vahl himself), and also as with a plant I have from
Bonpland under the name of Isolepis squarrosa H.B.K. [Humboldt, Bonpland & Kunth] (but whether
correctly so or not I leave to Nees v. Esenbeck to determine).

I may here mention that I cannot distinguish what you
have sent me as Fuirena hispida Ell. (from Alabama), from your
F. [Fuirena] squarrosa (from New Jersey) except by the leaves being a little
longer, but begging your & Elliot's parson, if that be all the difference,
it is somewhat puerile. A species can only be distinguished
from another by a positive not a relative character. So for as
decided characters can be had from the state of the perigynium 
or hypogynous scales, I will admit then but I really do not find
the differences pointed out therein by Elliott to accord. Your F. pumila
is much more distinct. Besides if any trust is laid on the pilosity of
the plant (but I place little) your F. squarrosa is not the same
species as Elliott's nor as a species I have long had under that
name. In all I have seen bristles more or less perfect, alternating
with the hypogynous scales.

I intended to have sent you a few extracts from a note of
Nees v. Esenbecks now lying before me; giving a few notes on N. American
Cyperaceae, either new, or unknown tos N. America; but my time will
