The plant appears to be known only from the type collection, 

 . Little Belt Mts., Montana, Flodman. 

 / Mitella stauropetala. Scapes naked, 3-5 dm. high, slender, 



sparsely pubescent below, minutely gland ular-puberulent above! 

 leaves orbicular, indistinctly 5-lobed, simply or doubly crenate but 

 not strongly so, reniforra with the sinus narrow or even closed, 

 sparsely pilose on each surface and ciliate with reddish or white 

 hairs; raceme 6-12 cm. long, 10-25 flowered, strictly secund ; 

 flowers white, sometimes violet-tinged, sessile or nearly so, evenly 

 scattered, spreading in anthesis but tending to become erect in 

 fruit, 4-5 cm. long ; calyx-lobes erect, oblong-obovate, faintly 

 crenulate, about equaling the funnel-form tube, 3-nerved ; the 

 mid nerve simple, the lateral ones with 4-6 branches, the lower of 

 these again branched ; petals nearly twice as long as the calyx- 

 lobes, filiform, 3-parted nearly half their length into linear lobes, 

 the lateral lobes divaricate ; stamens short and included.

The plant of Douglas, " plentiful in woody situations on the low 

 ridge of the Blue Mts. of Lewis and Clarke's [Snake] River, west of 

 the Rocky Mts., in lat. 46°," referred by Hooker, Fl. Bor. Am. I. 

 241, toilf. trifida, is with scarcely a doubt the species here described. 

 Douglas' journal shows clearly that the above locality is what is 

 now known as the Craig Mts., Idaho, the type locality of our 

 species.
