GERANIACEAE (GERANIUM FAMILY) 303 



glands: leaves small, round-reniform or the cauline truncate at base, equally 

 cleft into about 7 cuneate-oblong lobes, each more or less regularly 3-toothed 

 at apex: peduncles distributed along the stem: petals pale to deep violet, 

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

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

 cent, not wrinkled. Adventive in a few places in our range. 



2. Geranium carolinianum L. Sp. PI. 1: 682. 1753. Erect, diffusely much 

 branched from the base, or nearly simple, 1-5 dm. high, pubescent: leaves 

 2-5 cm. in diameter, palmately 5-7-lobed or parted, the divisions cleft into 

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

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

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

 Across the continent, but rare in our range. 



3. Geranium caespitosum James, in Long's Exped. Am. Ed. 2. 3. 1825. 

 Caespitose-tufted, lightly grayish-pubescent throughout, not glandular: leaves 

 orbicular-reniform, deeply 5-7-cleft: sepals oblong, scarious-margined, aris- 

 tate: petals generally rose-purple, obovate, scarcely longer than the calyx, 

 bearded near the base within with straight white hairs: filaments pilose: cap- 

 sule softly pubescent. [G. atropurpureum Heller, Bull. Torr. Bot. Club 25: 195. 

 IS! is; G. Cowenii Rydb. (?).] Central Colorado but occasionally north to 

 Wyoming and south to New Mexico. 



4. Geranium Richardsonii F. & M. Ind. Sem. Hort. Petrop. 4: 37. 1835. 

 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 sometimes purple: capsule puberulent or 

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

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

 -Mexico. 



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

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

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

 nearly orbicular, with cordate or reniform base, deeply 3-parted, the lateral 

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

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

 G. iiicixtun. 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 

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

 but stouter and often 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 Engelm. 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 longipes. Indigenous in the moun- 

 tains of western Colorado and Wyoming and in Utah.
