          master here [Asa Gray] being of like opinion, I put them together, without
 a doubt or hesitation. Indeed, Mich'x'. [André Michaux's] own figures would
 warrant it without the other [Megnant?] (negative) evidence.
 As to Aiton's [William Aiton's] P. laevigata [Populus laevigata], with "3-nerved leaved," it was
 raised on a cultivated tree, & may or may not be North Am'n. [American]
 as he supposed. At any rate, we have nothing like it. All our
 specimens (very few however) are clearly Aiton's P. monilif. [Populus monilifera]
 with "spreading nerves" & cartilag. [cartilaginous?] teeth incurved." You will
 remark that Hook. [William Jackson Hooker] took exactly my view as to the probability
 of Mich'x' [André Michaux's] S. canad.  being the same thing. (Fl. B.Am. [Flora boreali americana] p. 155)


 I am now beginning to dig into the Carices [Carex]. As you
 remark Emerson has relied on Barratt, & clearly did
 violence to his own better judgment in doing so, both as to
 the Salices [Salix], and even in this last matter of the Populi, wherein
 B. had a conceit about the colour of the styles, &c., &c.! for
 distinction. I have found some of his Salices in my
 brother's set, ridiculously at variance with his own (even
 sectional!) characters. Please send, in your next, a
 spike of Tuckerman's [Edward Tuckerman's] C. alopecoidea [Carex alopecoidea], which you adopt
 & which I supposed was the same as Dewey's [Chester Dewey's] new
 cephaloidea [Carex cephaloidea] (which you do not notice, even as a Syn. [synonym])
 It cannot be so, however, as Dewey in [Alonzo] Wood's (!!!) Bot'y [Botany]
 has now the 3 species cephalophora, alopecoidea, & 
 & cephaloidea! Of the first & last you make no mention.
 If you have as spike of each, from Dewey, or Sartwell [Henry Parker Sartwell]
 (who knows his species) I should like to see them. I am
 more than ever convinced of the distinctness of C. steudelii [Carex steudelii, now Carex jamesii],
 tho' I remember you told me you were not satisfied with
 it, & I observe that your char. [characterization] of C. Willd. [Carex willdenowii] is made to include
 both forms. I separate them thus-- C. Willd has
