to C. tenuiflora; C. Coryli to crenulatas C. Saururi to C. 
umbrosa, Beyr. (they are probably identical) ; and C. Poly- 
gonorum to C. chlorocarpa. Also Lepidanche Compositarum 
should have been altered to L. squarrosa. But, on con- 
ferring with Dr. Asa Gray, we thought it imprudent to 
adopt so extensive an alteration, however desirable it might 
have been. The names would certainly be more appropriate; 
except perhaps in the case of C. umbrosa, which grows along 
Open sunny ponds as well as in shady places ; but still this ap- 
pellation, being the older one, must be substituted for mine. 
The most important corrections are as follows : 
C. Cephalanthi is generally 4-parted. 
C. vulgivaga has a considerable stylopodium, as the figure 
3. e. shows. 
- C. Saururi is distinguished from the foregoing species, less 
by the proportion of its parts, than by the open corolla, of 
finer texture, the lobes of the calyx and corolla not orbiculate 
. 9r ovato-orbicular, but oblong or even linear-oblong. :
