          presentation copy I do not like to spare it: though I will of 
 course lend it to Dewey, if he wishes it before he can procure
 it from London, through the booksellers. 


 Your Ericaceous questions come at an inopportune time
 for me to answer. Some of them I am unable to answer; nor 
 can I [predict?] the shape which some of them will assume
 when they come up for the Flora. According to my notion 
 however, you will have to keep [Monotropeae?] as a sub order if you do,
 Pyrolaceae, &c. How does it differ from Ericaceae, comprehensively
 considered except in the want of green foliage. (which happens 
 with some Orchidaceae &c.) When you are ready I will send you
 both editions of Linn. spec. pl. [Caroli Linnaei ... Species plantarum] if you wish them. Indeed I
 see not how you are to go on, and advanced of the Flora, without 
 them.


 Zuccarini wrote me a year ago, when he sent the Japanese 
 plants that we looked over together, that the Japanese species 
 utterly confounded the difference between Rhododendron & [crossed out: Azalea?]
 Azalea: decandrous species having deciduous leaves, &c. 
 If they must come together (and DC. [De Candolle] seems doubtful) it would 
 be pity you did not follow that plan, as you so early adopted it.


 Then after all, in such case, are the Azalea's, as they will ever be 
 called [added: in cultivation,] to make the section Azalea, or is A. [Azalea] procumbens to take that 
 name? 


 In mss [manuscripts], I have not hesitated to adopt the Linnaean speficic [specific] 
 name of hispidulum for the Chiogenes, as I think I wrote I wrote you. 


 In an old letter I gave my view about the sections of 
 Vaccinium, to one of which I reduce Oxycoccus (which I think 
 I must have done were there no V. [Vaccinium] erythrocarpum, which by the way, 
 I put into a separate section) 


 But your great difficulty is with the names even of your
 common Vaccinia, nearly all of which, except corymbosum, will 
 vary greatly as to names from the common acceptation. 


 I know not what you will do, if you must print them before 
 April or May. I should need an entire week, with a very clear 
 head to put the nomenclature of the genus into shape from the means 
 in my hands and Boott's curious new comparisons.
