          lance ovate, sub-mucronate: their points, as well as the [?]
 of the leaflets, tipped with browish red. Grows in light sandy soil,
 two to four feet high. Colour of the plant, [hoay?] green. Flowers
 last of June & through July. Not common.


 This description differs from all those of P. pennsylvanica
 that I have seen, in the following among other particulars
 1. In P. pen. the true terminal leaflets are connate and the
 inner alternate. In this ^ [inserted: species] they are not connate. ^ [inserted: but] the terminal
 one is petaled and the inner leaflets are mostly opposite.
 2. In P. pen. "The stem leaves are sub-digitate, but pinnatifid"
 In this they are pinnate. 3. The flowers of P. pen. are small
 and yellow - in this, large and white.


 I received a letter from Dr. Cooley of Deerfield Mass. in which
 he mentions that you would like to exchange specimen
 in Geology and Mineralogy with some one in that region _ [page torn out here]
 be happy to furnish you with those I have collected [page torn out here]
 if the thing be practicable. I shall probably return to Deerfield
 after commencement (Sept 7th) and if I can get an opportunity
 to send you a box of specimens I will pack one for
 you. Or perhaps I shall return & spend the winter at N. Haven
 and in that case can forward by a packet. Opportunities of
 sending directly from Deerfield to N. York are very rare - and
 my pursuits are of such a kind that I am unable to devote
 a great deal of time to collecting specimens, yet I rejoice if at
 any time I can [throw?] [effaced; ?] my mite in the great[remainder of page torn out]
 of Natural Science. Permit me to thank you for [remainer of page torn out]
 valuable addition you have lately made to the botany of our
 country, by your "Catalogue" of the N.York Plants_ and believe me
 very respectfully your humble Servant


 Edward Hitchcock


 P.S. A line directed to me at N. Haven will find me if sent
 previous to Commencement
