7. G. richardsonii F. & T. Little-dick Geranium. Stem rather slender, 

 from a stout simple or branched root-crown, 1^2 to 2^/4 feet high ; leaf-blades some- 

 what appressed-pubescent, the stems and petioles pilose or hirsute with spreading 

 hairs, sometimes retrorsely so ; blades of basal leaves deeply 5-parted into toothed 

 or cleft segments, the petioles 3 to 12 inches long ; hairs of the pedicels tipped with 

 purple glands; petals white, sometimes pink-tinted, mostly roseate-veined, hairy 

 within, 5 to 6 lines long. 



Moist mountain meadows or openly wooded canons, 5500 to 9000 feet: high 

 mountains of Southern California; Sierra Nevada from Tulare Co. to Lassen Co.; 

 Humboldt Co. at 800 feet. East to New Mexico, north to Saskatchewan. July. 



Geog. note. — In Southern California the purple-flowered forms cannot otherwise be dis- 

 tinguished from the usual white form of G. richardsonii, especially its prevailing form in the 

 Sierra Nevada. The pubescence of petioles may be either spreading or deflexed or retrorse in 

 either G. richardsonii or G. incisum, while the glandular character is variable in both species. As 

 G. incisum, entering California from the north, ranges southward in the Sierra Nevada it be- 

 comes less coarse, less glandular and tends to approximate G. richardsonii in slendemess and in 

 smaller flowers.
