13. M. heterophylla Jepson n. comb. Stems 5 to 11 inches high, rising 

 from tuberous rootstocks or cormlets, these sending out slender stolons which 

 produce terminal cormlets, the secondary cormlets promptly producing leaves 

 and flowers; basal leaves narrowly ovate to oblaneeolate, acute, y^ to 2 inches 

 long, on long slender petioles ; cauline pair similar, subsessile ; raceme 5 to 11- 

 tlowered; pedicels becoming •% to 1 inch long; sepals round-ovate, obtuse or 

 fsubcordate at base, 2 lines long; petals white, pink-veined, notched, twice as 

 long as the sepals. 



Southern Sierra Nevada. 5700 to 7000 feet. Oregon to Alaska. The tubers 

 or tiesliy rootstocks each produce only 1 or 2 stems and leaves, whereas in M. 

 sibirica the numerous leaves and stems form l>y their bases a thick crown on 

 the slender or fibrous taproots.

 round-ovate, obtuse to aeutish, % to 1% inches long, on petioles 3 to 6 inches 

 long; cauline pair similar, obtuse or often more acute; raceme loosely 3 to 8- 

 flowered, the pedicels Vi; to IV^ inches long; sepals orbicular, truncatish, li/o

 than one day. Sepals 2. Petals 5, distinct and equal. Stamens 5. Ovules 

 few, about 6. Style-branches 3. Capsule 3-valved, 3 to 6-seeded. — Species
