scarcely over half inch long, rather stout : calyx densely woolly-villous, many of its hairs 



glaud-tipped : filaments loug-pilose : beak of fruit cauescent and somewhat villous. Prodr.

++ ++ At least the pedicels conspicuously glandular-pubescent : petals more or less beset 

 on the inner surface with long white rather stiff hairs : filaments villous : fruiting pedi- 

 cels spreading or reflexed and bent. 



G. incisum, Ndtt. Coarser than the preceding and leafy-branched : pedicels and often 

 petioles or even the entire plant dingy glandular-pubescent with rather short hairs, and 

 somewhat unequally and commonly retrorsely villous, or occasionally (in a slender form) 



canescent with very short incurved hairs : petals purple : beak of fruit very glandular.

Woods and open places ; the coar.ser more villous form from the mountains of Brit. Columbia 

 and Saskatchewan to Oregon, Idaho, and S. Dakota ; the slender more canescent form from 

 Central California to Oregon, Idaho, and Utah. A form doubtfully referable here, with 

 the purple glands of the next species and seemingly glabrous magenta petals, occurs in 

 Oregon, Miss Miilford. Some Washington specimens have the glandular hairs almost con- 

 cealed beneath the very abundant long hairs. 



G. Richardsonii, Fisch. & Tractv. Slenderer, inconspicuously retrorsely pubescent 

 below, the peduncles and pedicels and sometimes the upper part of the stem villous with 

 long white hairs tipped with purple glands : leaves thin, the uppermost with tlie terminal 

 lobe longer than the often greatly reduced lateral lobes : pedicels straighter : petals white, 

 mostly roseate-veined : beak of fruit sparingly pnberuleut and glaudular-villous. — Ind.

 G. Hookerianum, Walp. Rep. i. 450. — Open places and ravines in the mountains, Saskatch- 

 ewan to Utah and New Mexico. A reduced very slender occasionally somewhat cespitose 

 plant, scarcely to be referred elsewhere, occurs in the mountains of New Mexico, Wulcott; 

 Arizona, Knowlton, Lemmon ; and S. California. Some Colorado specimens have leaves ap- 

 proaching those of G. Fremontii in outline, and it is not certain that the two species do not 

 hybridize. 



G. Mexican um, HBK. Slender, a couple of feet high, coarsely white hairy, the hairs ap- 

 pressed on the leaves, but little glandular : leaves 3-lobed with openly V-shaped basal sinus ; 

 the lowest very long-petioled ; the uppermost less than an inch long, with the lateral lobes 

 greatly reduced : flowers sbort-pedicelled : petals white, about 4 lines long : fruit not seen.

 Arizona, Lemmon. Perhaps also Rio Zuni, New Mexico, Wooton. (Mex.) 



-t— -1— Spreading and cespitose from the branched summit of the caudex, leafy-branched : 

 leaves firm, of medium size (1 to 3 inches), 3-parted with broadly cuneate divisions ; the 

 cauline mostly truncate at base, incisely once or twice 3-lobed at apex ; the lower once or, 

 especially in radical leaves, twice cleft on the lower side : petals villous within : fruiting 

 pedicels refracted. 



G. Fremontii, Tore. A span to a foot or two high, the smaller plants sometimes sub- 

 acaulescent, the larger with slender spreading leafy branches, dingy glandular-pubescent at 

 least above : petals rather light rose-purple : beak of fruit dirty-glandular. — Torr. in Gray, 

 PI. Fendl. 26, & in Marcy, Rep. 303, t. 3 ; Trelease, 1. c. 75. — Mountains, from the Black 

 Hills to Utah and New Mexico, extending, in a more loosely branched perhaps separable 

 form with longer and paler glandular hairs, into Arizona, Knowlton, Lemmon ; and S. Cali- 

 fornia, Parish, Orcutt. A tall form of the Colorado mountains, with loosely villous as well 

 as short glandular pubescence, and often slender elongated petioles, is var. PArryi, Engelm.

G. caespitosum, James. Usually slenderer, often rooting at the nodes, with longer 

 slenderer retrorsely hispid or canescent but not glandular pedicels : petals roseate to rich
