My Dear Sir,

I have not written to you for a long time as
I have had nothing to communicate worthy of your consideration.

I now enclose Carex retroflexa Muhl. which our worthy
friend Carey considers a good species founding his opinion
on the smoothness of the beak of the perig. which certainly
serves to distinguish it from Carex rosea.

I hope you received the continuation of the List of R. I.
plants and that my change of the name of your Scirpus
Mucronatus met with your approval. I have just recd. [received]
a letter from an English friend who writes thus.
"The plant sent as Scirpus mucronatus is very different
from the plant so named by European Botanists; I have two
specimens of this plant, both gathered by Koch himself near
Erlangen, where he resides. I have not yet had an opportunity 
of comparing [crossed out: my] it with the plant in the Linnean Herbarium.
I will enclose the one of these specimens. I have compared 
[my?] plant with all the Scirpii within my reach and am
