Boston  Apr. 22  1817

                Dear Sir

                         Your letter of 16^th is just received.  The  Tholeus  odoratus  flowers about May 10-20 in wet grounds, edges of meadows, &c.  A spec. is inclosed.  A dissection showing the calyx, corolla, stamen, & styles , separate, will be acceptable when perfectly convenient.  You refer to a list of plants in Deerfield lately sent to me.  I have not received any such list & doubt not that it must have miscarried.  If you will inform me by whom it was sent, I shall probably be able to look it up.- To the list of plants which I have requested Miss White to paint, I will now add the following Indian corn, Potatoe, Wheat, Rye, Oats, Barley.- These if re-copying may be of the size of a quarto page As the corn is rather an unwieldy specimen for a single page, I have cut it up in a sketch on the opposite page.  It is made at random for many but may serve as some guide.-  Of the potatoe I should like a stem or two in flower, & a specimen of the fruit & root.

                                very truly yours
