60 EARLY UNDERTAKINGS. [1836, 



A letter which Dr. Torrey has just received from 

 Mr. Arnott gives me the information that you have 

 honored my attempt at a monograph of Rhynchospora 

 by commencing the reprinting of it in the " Companion 

 to the Botanical Magazine." I might justly be proud 

 that my first attempt should be thought worthy such 

 notice ; but I wish it had been delayed until you could 

 receive the monograph " Cyperacese of North America " 

 of Dr. Torrey, in which I had occasion, in the revision 

 of our Rhynchosporae, to make some important altera- 

 tions and corrections, as well as to introduce a new 

 species and specify some additional localities. The 

 paper referred to I hope you will receive with this 

 letter. 



Except a few extra copies, all the sheets of the mon- 

 ograph " Rhynchosporae " were destroyed by fire soon 

 after being printed, and when reprinted, about a year 

 since, I added a few observations, notes of additional 

 localities, etc. But owing to a want of careful revi- 

 sion I find there are several errors (several of which 

 are quite material), some of the pen and others of the 

 types. I hope these have been detected and corrected 

 in the course of the reprint. I send herewith the 

 sheets of the paper as published here, with such typo- 

 graphical corrections as now occur to me. Would it 

 not be proper to append a reprint of the revision of 

 Rhynchosporae in Dr. Torrey 's monograph, a copy of 

 which I hope will reach you with the present letter. 

 If the specimens I send please Mr. Webb I shall be 

 glad. It is the last perfect set I have. Please make 

 no remittance, since the sum is too trifling, and more- 

 over I may soon have some favors to ask as to its dis- 

 posal. Indeed, I know not why I should not state 

 that there is some probability that I may soon visit
