          I have De Cand. [De Candolle's] Prodromus through Vols. 7-- I shall
 be very glad, when you import the remaining vols.
 for yourself, that you would procure one for me also.


 You did not tell me in your last the cost of
 those fine lenses, you wrote about last Oct.


 Of the plants you write about in your last, I
 find that I had guessed nearly all as you have referred
 them. It was however little but guessing, for I
 have done little at studying plants for two years.
 Is not Malva Houghtonii the M. triangulata [Malva triangulata], Leaven?
 I have only the short account of the latter in [Amos] Eaton, but
 it seems to apply to your plant. 


 If I remember the Hypericum (c), it was one of the suffruticose
 species. You call it "H. Parviflorum var." Is it not
 H. prolificum? The plant which I called "Koeleria?"
 I have not examined for several years, but I remember
 that when I first collected it, I was struck by its
 close resemblance to Koeleria,  the awns aside; hence the
 name I applied. I know not what it is. I wish you would
 compare it with Trisetum palustre [now Sphenopholis pensylvanica], & see if it can be that.
 The "Panicum-- a form of C. anceps?" struck me as being
 perhaps your P. carinatum [Pannicum carinatum, now Cyrtococcum patens] in my Catalogue, but I had
 neither specimen nor description to compare it with. Suppose
 you compare them. The plants which I felt
 most anxiety about, you have not alluded to. They
 were those I described as new, together with a Carex
 from Washington, Cyperus from French Broad River, Linum,
 Neurophyllum, Polypogon, Prunus, Urtica, & particularly
 those marked Cruciferae, & Pinnata.
