164 THE CORRESPONDENCE OF SCHWEINITZ AND TORREY 
allowed me, my observations here in Pennsylvania generally to 
confirm my opinions. The only species which I think admit of 
further doubts are—whether V. cucullata & obliqua ought not 
to be united after all; whether cordifolia be not too near villosa 
Ell. & whether repens should be separated from ochroleuca— 
Of the rest I am pretty certain. V. pubescens common here & 
never found in N. C. is extremely different from eriocarpa. Is not 
the V. Selkirkii you mention perhaps related to my punctata from 
Labrador? The specific difference of V. palmata & asarifolia (the 
latter never occurs here but is common at Salem) is beyond 
doubt 
Accept of my best thanks for the curious little moss from 
Florid[a] & the highly interesting Roccella from Thule. I conceive 
however that the Captains who assert this to be the only vegetable 
there, do not regard crustaceous Lichens as such—for I cannot 
believe that any rock is utterly devoid of such. 
I shall be much obliged to you for the subterraneous fungi 
from the Coppermine. 
Tho’ I am almost perfectly ignorant of mineralogy—I read 
what you communicate on that subject with great interest, as 
everything concerning natural history is valuable to me. But 
still I must confess to you, that I am too much of a devoted 
Botanist, not to feel a little jealous, that the sister science appears 
to injure Botany by thus withdrawing from it, its most able & 
active cultivators like yourself and Mr. Nuttall. I hope however 
you will no more desert the service of Flora than he for that of 
Plutus or at least some of his cousins. 
The Roccella you so kindly sent me puts me in mind to request 
you if possible to procure me a specimen of the common Roccella 
(which I believe may be had in shops—as it is a dyeing article). 
I have lost the imperfect one I had & your gift has reinstated the 
Genus. 
Any tropical specimens of whatever kind would likewise be 
acceptable to me—& very much so—plants from the South of 
Europe in which I am very deficient. 
With sincere respect & esteem I remain 
Your obdt Servt
