You are indeed an invaluable collector, though you do like to grumble now and then, and I hope the Indians won’t catch you. If they must take a scalp or a head, there are others I could better spare. So take care of yourself....
I carefully keep your flowering bit of Fendlera, ready to return it if Lindheimer does not get more, as I trust he will. It is the most interesting of North American genera, between Deutzia and Philadelphus, and shows plainly that both are saxifragaceous....
I am worked almost to distraction. But college work is now over and I can get on with fewer irons in the fire.
I fear you are driven up hard also, by the sickly season and cholera. I hope you may be able to give up practice by and by....
I have had for a good while a misunderstanding with Captain Wilkes about my work for the Exploring Expedition botany. It is now made up, I think, or nearly, but I have had no pay from them for a long time, and they are a year behind in paying. I have got manuscript of several families all ready for the press, and some fine drawings. I am just now working up “Plantæ Wrightianæ,” 1851 collection, up to end of Compositæ, old stopping-place, but must dash beyond that soon....
Here is a discovery! I have to-day received by post from Dr. J. F. Beaumont, of Mountain Home, in the upper part of Alabama, specimens of a Trichomanes, which he finds growing there under shelving rocks. I send you herewith the half of what is sent me, knowing you will be much interested in the discovery, for the first time, of a Trichomanes in the United States; and thinking that you will probably pronounce it to be a form of the T. radicans, though so much smaller than my Irish and West Indian specimens.... I have not specimens enough of T. radicans to satisfy myself entirely, and refer the question to your experienced judgment. Pray give me your opinion, for the addition of a single species to our few ferns, and especially one of this group, is a matter of moment to us, and worthy of a published notice.
I should not be so greatly surprised now if Hymenophyllum ciliatum, credited by Willdenow to Virginia, should turn up, but I still think there was some mistake about that; and I could find no specimen in Willdenow’s herbarium when I sought for it, in 1839....
