My Dear Sir,

I am favoured this morning with your letter of the 31st July
and thank you for the information regarding the Scirpus and for the imnteresting
plant which you have kindly sent my by request of our mutual friend Doct.
Gray. I am under obligation to this gentleman for introducing me to your
notice.

I will seize with much pleasure the opportunity you have given me of
asking your advice regarding any doubtful species of Cyperaceae, and if I
can be of any service in collecting any thing you want this way it will
afford me pleasure to do it.

Your good advice and any show plants that are useless to you
either for your herbarium or exchange will amply compensate me for any
labour in collecting for you so that I hope in view of these things it
will induce you to [fully?] command my services.

I ought to [be?] first with the scirpus as I discussed it last year but
had no one to give me information about it. I have given my description
to day to Doct. Gray by mail with a request that he will name and
describe it. This should be done quickly and I have suggested a
daily paper [here?] to him. I thought Doct. G[Gray] the proper person to do this
in as much as you had received it from another source. If? I knew
the [?] botanist I would appeal to him to give me this plant.

I have found nothing new in Cyperaceae ([added: new] to me) the last week
[save?] the [Prolefus?] [Capelluris?] RS and your Tricelostylis mucronulata
both not rare I believe. I will send you a list of my
