Dear Sir

Some time ago I sent you by Mr. Le Conte
the only drawing I could make this summer for you, Acerates
longifolia.  Enslenia I had collected, but found in this very
sickly season no leisure to figure. The new Asclepias,
similar to A. amplexicaulis, which I had called A. glaberrima
I could not find; the large plain of the American [?bottom],
a bottomland of the Mississippi opposite StLouis, where it
has been collected by me near 12 years ago had been
overflowed last year, and hundreds of Acres of the
lower parts are [crossed out: now] [added: since] covered with a most luxurient
growth of Iva ciliata, which kills everything else.
other parts are under cultivation, so that it will be
difficult to discover this interesting plant again.
At the time I collected it, I was struck with it as
being one of the latest species of the genus in flower.

I hope you have safely received the texas plants
sent to you some time in April or May.

I have a few days ago had the pleasure to look through
Capt Fremonts Collection made in June & July; I understand
Dr McDowell is to deliver it to you. Among the plants
of the families described in your flora, I have been
most interested in your [C?is] perennis, which Dr McD
informs me is common on the upper Arkansas; a new
Dysodia and a large and probably new G[?]delia with
a copious pappus. There are 4 species (all described?)
