Stems simple, leafy, from running rootstocks. Leaves mostly sessile, oblong

 panicle or simple raceme, pedicels jointed at the summit. Stamens 6; the 

 filaments subulate. Style short, thick, persistent; the stigma 3-lobed at the 

 summit; ovules 2 in each cell. — (Vagnefa Adans.) 



Flowers in compound racemes (panicles). 



Leaves short-petioled; flowers very numeroua . . , , I. S. racemosa. 



Leaves sessile and clasping; flowers fewer . • . « • 2. S. amplexicaulia. 

 Flowers in a simple raceme. 



Leaves acute, ascending, more or less folded 3. S. Btellata. 



Leaves acuminate, spreading, usually flat 4. S. sessilifolia. 



1. Smilacina racemosa (L.) Desf. Ann. Mus. Paris 9: 52. 1807. Minutely 

 downy, 3-8 dm. high: leaves numerous, oblong or oval-lanceolate, acuminate, 

 ciliate, abruptly somewhat petioled: flowers crowded, very short-pediceled: 

 stamens exceeding the short perianth-segments: berries pale red speckled with 

 purple, aromatic. — Moist copses; from the mountains in Colorado to the 

 Atlantic States. 



2. Smilacina amplexicaulis Nutt. Journ. Acad. Phil. 7: 58. 1834. Re- 

 sembling the preceding in size and habit: the leaves sessile and clasping: 

 flowers fewer, in an open panicle: stamens exserted: style long, nearly 

 as long as the ovary: berry reddish. — ^Throughout our range and west to 

 California. 



3. Smilacina stellata (L.) Desf. 1. c. 52. Stem smooth, 1-4 dm. high: leaves 

 smooth above, minutely pubescent below, dblong-lanceolate, sessile and some- 

 what clasping, 3-8 cm. long, usually folded on the midrib: filaments shorter 

 than the perianth: berry at first green with dark stripes, becoming red when 

 ripe. (Vagnera leptopetala Rydh. Bull. Torr. Bot. Club 28: 268. 1902.) — In 

 moist woods and meadows; from New Mexico north to the boundary and 

 thence across the continent. 



4. Smilacina sessilifolia Nutt. ex Baker^ Journ. Linn. Soe. 14: 566. 1875. 

 Rootstock slender: stem a foot or two high: leaves lanceolate, acuminate, 

 sessile, usually flat and spreading, somewhat puberulent: raceme larger and 

 pedicels longer (6-12 mm.) : segments of the perianth lanceolate, twice as long 

 as the stamens: berries usually black when mature. (Unifolium Uliaceum 

 Greene, Pitt. 1: 280. 1889.) — Northwestern Wyoming to Montana and west 

 to the coast.
