1. CAREX IN THE CHECK-LIST.—There are two or three 
features of the Carex catalogue in the ‘‘List of Pteridophyta 
and Spermatophyta” which do not represent my own views 
(although my name is attached to the article), and to which I 
wish briefly to advert. My chief reason for discussing the 
subject is to bring up one or two features of the nomenclature 
of the Check-List. 
My first remark has reference to the double or alge- 
braic citation of authorities. It is admittedly the purpose of 
all citation of authority to identify the name; giving honor or 
‘‘credit” to the author of the name is no part of the object. 
If we adopt the double citation system, we enclose in our 
parenthesis the name of the author of the given specific or 
varietal name, and this is followed by the author of the ac- 
cepted combination; or if only one name is cited, it is under- 
stood to stand for both the creation and the combination. 
Thus, Carex granularis Haleana (Olney) Porter, means that 
the name Haleana was first proposed by Olney and was 
placed in combination with Carex granularis by Porter. But 
now suppose that Olney himself, instead of Porter, had later 
attached the name to Carex granularis. The proper citation 
would, in that case, certainly be Carex granularis Haleana 
(Olney) Olney. 
But this method the Check-List does not allow, although 
Ido not know why. Attention was called to it at least twice 
when the List was going through the press. 
; Let us take a concrete example. Carex no. 772 in the list 
Is Carex cephaloidea Dewey, Rep. Pl. Mass. 262. ( 1840).
