 SMILACINA Desf. (1807) 



Herbs with simple leafy stems, broad mostly sessile alternate 

 leaves and small white flowers on jointed pedicels in terminal 

 bracteate racemes, or panicles. Perianth persistent of 6 distinct, 

 1-3-nerved segments. Stamens 6: filaments subulate, inserted at 

 the base of the segments: anthers versatile, introrse. Ovary ses- 

 sile, ovate, 3 celled, with 2, usually collateral ovules in each cell. 

 Style short and thick. 3-lobed at the summit, persistent. Fruit a 

 globose 1-3-seeded berry. Seeds subglobose, with thin testa and 

 horny albumen. 



* Flowers panicled, very small: stamens exceeding the oblong-lan- 

 ceolate segments of the perianth. 



V. amplexicaulis Greene. Smilacina amplexicaulis Nutt. Stems several 

 from a stout elongated rootstock, 1-3 feet long ascending, covered with a 

 short spreading pubescence : leaves ovate to lanceolate 3-7 inches long, 

 strictly sessile and amplexicaul or sometimes with a very short dilated 

 clasping petiole, acute, rounded at base: usually pubescent with very short 

 stiff hairs : panicle sessile or shortly peduncled, 2-9 inches long : pedicels 

 solitary usually less than a line long; segments of the perianth less than a 

 line long : filaments more or less broadly subulate, often broader than the 

 segments : style nearly as long as the ovary : berries light red, finely dotted 

 with purple, 2-3 lines in diameter, usually 1-seeded ; seed whitish, 1% lines 

 broad. In the Coast ranges, Brit. Columbia to California. 



V. racemosa Morong Mem. Torr. Bot. Club, v, 114. Smilacina race- 

 mosa Desf. Stems often stout, erect or ascending, somewhat angled, finely 

 pubescent above or nearly glabrous, 1-3 feet high, from a thick fleshy root-
