NOTES, 
Convolvulus suffruticosus, Vol. 2, fol. 139; and Convolvulus pannifolius, 
fol. 222, of this volume. 
Mr. Herbert, who has given peculiar attention to the hybrid intermix- 
tures as well as seminal variations of species, writes to us, that he is con- 
vinced that the latter of the above two plants is purely a seminal variety of 
Convouvutus canariensis; aud that he suspects the first to be another 
variety of the same. Upon this head we can take no responsibility to oure 
selves ; we have recorded them as distinct because they really differed, and 
we found them so recorded in books of the first authority. But experience 
is the certain test of variety and species; and if pannifolius has been raised 
from the seeds of the true canariensis, there is an end of the question, We 
are highly obliged to Mr. Herbert for the communication, as well as much 
other valuable assistance, 
Hyoscyamus canariensis. Vol. 3. fol. 180.

for that of GRINDELIA, see the 248th article in this volume. Іп the above, 
for Doxta read GRINDELIA. 
Silene pensylvanica, Supra fol. 247. on 
The English text of that article, which begins, * The SıLexe virginica 
of Linnaeus and the Sieve Catesbei of Walter, have been adopted by 
Willdenow as distinct species,” &c.; should have stood as follows: 
* The SILESE virginica of Linnaeus and the SiLENE caroliniana of 
Walter, have been adopted by Willdenow (the latter under the title of 
Sitrene Catesb@i) as distinct species, &c.
