purple, turning brown, seemingly more spreading or reflexed than in related species : beak 

 of fruit gray-pubescent : otherwise closely resembling the last, which it approaches by vari- 

 ously glandular forms of the extreme Southwest, while a few specimens with the pubescence 

 of tliis species rather than of G. Fremontii have been collected in Colorado, Wyoming, and 

 California. — James in Long, Exped. Am. ed. ii. 3, as ccespitose ; Torr. Ann. Lye. N. Y.

wrinkled : seed deeply pitted, subglobose. 

 G. coLUJiBfjJUM, L. Very slender, spreading and prostrate, hispid with short close retrorse 

 gray hairs which on the calyx are nearly confined to the nerves ; not glandular : leaves ."5- or 

 5-di"vided and dissected into numerous linear divisions : petals rose-purple : beak of fruit ap- 

 pressed-hispid. — Spec. ii. 682 ; Trelease, 1. c. — Pennsylvania, Virginia, and S. Dakota.

 G. Carolinianum, L. A span to a foot high, spreading wlien large, loosely gray-pubes- 

 cent and mostly dingy-glandular : leaves incisely 3- or 5-parted, the cuneate segments more 

 or less deeply cut-toothed or dissected, with the ultimate divisions rather broad: peduncles 

 and pedicels seldom over an inch long, at length often densely crowded among the upper 

 leaves : petals rose-colored : beak of fruit loosely villous or glandular ; carpels villous-hispid, 

 usually black ; seed low-reticulate. — Spec. ii. 682 ; Trelease, 1. c. G. atrum, Mceiich,

 usual is G. Dicknellii, Britton, Bull. Torr. Club, xxiv. 92.

 primary lobes : peduncles long and spreading ; pedicels scarcely bent. — Bot. King Exp.
