flowers on long (1 to 2^4 inches) pedicels; sepals orbicular to ovate, obtuse; 

 petals white with pink veins or pink with rose-purple lines, coarsely notched,

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 oblanceolate, acute, l /2 to 2 inches 

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

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

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

 sibirica the numerous leaves and stems form by their bases a thick crown on 

 the slender or fibrous taproots.

14. M. asarifolia Howell. Stems erect, naked save for one cauline pair of 

 leaves, 7 to 12 inches high, arising from a horizontal rootstock; basal leaves 

 round-ovate, obtuse to acutish, % 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 */2 to 1*4 inches long; sepals orbicular, truncatish, iy 2 

 to 2 lines long; petals white, merely retuse, 3 to 5 lines long.

4. CLAYTONIA Gron. 



Low glabrous perennial herbs, the stems and basal leaves from globose deep- 

 seated corms. Stems scape-like, bearing at summit a pair of opposite leaves 

 and between them a several-flowered loose raceme. Flowers opening for more 

 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 

 about 8, North America and Asia. (Dr. John Clayton, American botanist, of 

 the colony of Virginia, who furnished Gronovius the materials for the Flora 

 Virginica; died 1773.) 



1. C. lanceolata Pursh. Stems 1 to 24 from a corm, erect, 2 to 4 inches 

 high; corm globose, about y 2 inch in diameter; basal leaves few or rare, nar-
