HOMONYMOUS NAMES. 
_ The Committee on Nomenclature of the Botanical Club adop- 
ted, at Rochester, an article which declares that “the publication 
of a generic name or a binomial invalidates the use of the same 
name for any subsequently published genus or species, respec- 
tively.” This rule, I am instructed, is to be enforced rigidly in 
the forthcoming Check List to be issued officially by the Club. 
The committee has also decided, by a recent vote upon Carex 
Michauxiana and C. Michauxii as a test case, that proper names 
differing only in their terminations are homonymous. It is with 
much regret and hesitation that I apply this rule to the carices of 
the Check List, although I fully sympathize with it. While the 
necessary changes are not numerous, they involve some of our 
best known species. The innovations which follow as a direct or 
_ indirect result of the homonymy of the Check List are as follows: 
’ CAREX ABACTA. 
C. rostrata, Michx. Fl. Bor. Am. ii. 173 (1803), not Stokes in 
With. Arrang. Brit. Pl. 2d ed. 1059 (1787). 
C. xanthophysa, vars. nana and minor, Dewey, Sill. Journ. xiii. 
353, figs. 57, 58 (1828), not C. xana Lam., nor Cham. nor Boott; 
minor has been frequently used in the genus. 
C. Michauxiana, Boeckl. Linnea, xli. 336 (1877), not C. 
Michauxii, Schw. (1824), nor Dewey (1826). 
CAREX ABBREVIATA, Schw. in herb.; Boott. Linn. Trans. xx. 141 
(1846); Ill. 21 (1858). C. Zorreyt, Tuckm. Enum. Meth. 21 
(1843), not C. Zorreyana, Schw. (1824), nor Dewey (1826). 
Boott originally attributed the herbarium name adéreviata to 
Prescott, but it was really Schweinitz’s, and the error is corrected 
in Boott’s Illustrations, i. p. 21. 
~CaREx Asa-GRAyI. 
C. intumescens, var. globularis, Gray, Ann. N. Y. Lyc. iii. 236 
(1834), not C. globularis, Linn. 
C. Grayii, Carey, Sill. Journ. 2d ser. iv. 22 (1847), not C. Gray- 
ana, Dewey (1834). 
~ Var. nIspipuLa (Gray). 
C. Grayii, var. hispidula, Gray in ‘herb: Bailey, Mem. Torr. 
- Bot. Club, i. 54 (1889).
