 somewhat notched: antheriferous stamens only 5 (exceptional in the genus); 

 fruit very small, with puberulent beak, the carpels 2 mm. long, finely canes-

 oblong-Unear lobes: pedicels short, crowded at the end of branchlets: petals 

 obcordate, pale flesh-color, equahng the awned sepals: carpels pubescent: 

 seeds obscurely reticulated. (G. Bicknellii Brit, as to plants of our range.) —

 Slender, erect, inconspicuously retrorsely-pubescent below, the peduncles and 

 pedicels and often the upper part of the stem villous with long white hairs 

 tipped with purple glands: leaves thin, 5-7-cleft, the uppermost with the ter- 

 minal lobe longer than the often greatly reduced lateral ones: petals white 

 with roseate veins, or seemingly someljjmes purple: capsule puberulent or 

 glandular-pubescent on the beak. (fi. strigosum Rydb. Bull. Torr. Bot. 

 Club 29: 243. 1902.) — ^Along streams in the movmtains; from Canada to New 

 Mexico. ; 



5. Geranium viscosissimum F. & M. Ind. Sem. Hort. Petrop. 9: Suppl. 18. 

 1835. Cbarser and leafy branched, dingy-viscid and glandular-pubescent/ at 

 least abovte, often throughout, 3-8 dm. high: leaves large, thick, long-petioled, 

 nearly orbiciilar, with cordate' or reniform base, deeply 3-pla,rted, the lateral 

 lobes deeply 2-lobed: petals purple, broadly obcordatp, 12-15 mm. long, 

 densely beairded at base: styles minutely hispid: beak of fruit very glandular. 

 G. incisum. — ^From Wyoming to the far northwest. 



6. Geranium Fremontii Torr. in Gray, PI. Fendl. 26. 1848. More or less 

 caespitose-tufted, rather stout, 2-4 dm. high; pubescence sparse, short, and 

 appressed, and viscid-glandular above: upper leaves deeply 3-5-cleft; the 

 radical ones 7-cleft, the segments 3-lobed or incised: petals mostly light 

 Jjurple, twice as long as the sepals, villous at base: beak of fruit dirty-glandu- 

 lar. [G. nervosum Rydb. 1. c. 28: 34. (?).]— Dry open hillsides; Colorado 

 to Idaho. 



7. Geranitmi Parryi (Engelm.) Heller, Muhl. 1: 7. 1900. Quite similar 

 but stouter and otten taller, with dense viscid pubescence throughout, of two 

 kinds, loosely villous- viscid and short-glandular: leaves 5-7-cleft; the lobes 

 obovate-cuneate, with ovate teeth: petals obovate, light purple or rose, with 

 darker veins: seeds reticulated. (G. Pattersonii Rydb. Bull. Torr. Bot. Club 

 29:242. 1902.) G. Fremontii Parryi'Enge\m. — ^Mountains of central Colorado 

 and probably extending into Wyoming and Utah. 



8. Geranium longipes (Wats.) L. N. Good. Bot. Gaz. 37: 56. 1904. Per- 

 ennial (?), at least biennial: stems simple below, branching above into 3-6 

 slender equal branches, each of which gives rise to 2-flowered elongated slen- 

 der peduncles: pedicels almost filiform, long: pubescence sparse-strigose, re- 

 flexed below, glandular-pubescent above: leaves reniform, 5-7-cleft nearly to 

 the base, the radical on long slender petioles: sepals oblong, long-awned: 

 petals narrowly obcordate, shorter that the sepals: ovary strigose-pubescent: 

 seeds oblong, pitted. G. carolinianum lorigipes. — Indigenous in the moun- 

 tains of western Colorado and Wyoming and in Utah.
