raceme ; stamens included; ovules not collateral; rootstock rather slender. 



2. S. stellata (L.) Desf. Plant (2-5 dm. high) nearly glabrous, or the 7-12

 woods, Lab. to N. C, w. to la., Dak., and Man. 



26. DISPORUM Salisb. 



Perianth narrowly bell-shaped, the 6 lanceolate or linear divisions deciduous. 

 Filaments thread-like, much longer than the linear-oblong blunt anthers. Ovary 

 with 2 ovules (in our species) suspended from the summit of each cell; style 

 one ; stigmas 3, short, recurved-spreading, or sometimes united into one 1 Berry 

 ovoid or subcylindric, pointed, 3-6-seeded, red. —Downy low herbs, with creep-

 leaves, and greenish-yellow drooping flowers on slender terminal peduncles, soli- 

 tary or few in an umbel. (Name from 8is, double., and airopd, seed, in allusion 

 to the 2 ovules in each cell.)
