VAGNERA (FALSE SOLOMON'S SEAL) 



Stem scaly below, leafy above. Leaves wide, alternate. Perianth 

 segments distinct, white or greenish white. Stamens on base of perianth ; 

 anthers introrse. Ovary sessile ; cells 2-ovuled ; stigma obscurely 3-lobed. 

 (Probably in honor of M. Wagner, a German traveler and naturalist.) 



A. Inflorescence a raceme, 3-2o-flowered; flowers 6-10 mm. long; perianth shorter 

 than the stamens. 



B. Leaves spreading, flat; racemes 3~9-flowered; perianth twice as long as the 

 stamens; rhizome slender. W. C. E. V. sessilifolia 



BB. Leaves ascending, folded; raceme 6-2o-flowered; perianth less than i$ times 

 as long as the stamens; rhizome stout, fleshy. E. V. stellata 



AA. Inflorescence a panicle, many-flowered; 'flowers 2 mm. or less long; perianth 

 longer than the stamens. 



C. Leaves acuminate, the lower ones with a very short petiole, not clasping. W. E.

 CC. Leaves acute, all sessile, more or less clasping. W. C. E. V. amplexicaulis 



DISPORUM (FAIRY BELLS) 



Stem branched, scaly below, leafy above. Leaves somewhat oblique. 

 Flowers rather small, in a terminal few-flowered umbel. Perianth segments 

 distinct. Stamens hypogynous; anthers extrorse. Ovary sessile; cells 

 mostly 2-ovuled; stigmas i or 3. (Gk. dis = double, spora = a seed; 

 because the cells of the ovary are 2-ovuled.) 



A. Leaves rounded or slightly cordate at base, not clasping; stigma 3-cleft. 



B. Plant much branched; perianth segments 12-22 mm. long; stamens about f 

 as long as the perianth; berry short-beaked, nearly smooth except at beak, 3-6- 

 seeded. W. C. D. smithii 



BB. Plant sparingly branched; perianth segments 12-14 mm. long; stamens about 

 equaling the perianth; berry not beaked, papillose, 3~i8-seeded. E. D. ma jus 

 AA. Leaves mostly cordate at base (except D. trachyandrum) , at least the lower mostly 

 clasping; stigma entire. 



C. Leaves averaging about 3.7-5 cm. long; stamens more than f as long as the 

 perianth; filaments elongated, longer than the anthers.
