11 YAGXERA, Adanson. Erect simple ample-leaved perennial, 

 with fleshy elongated horizontal rootstock, fibrous roots, and a terminal 

 simple or compound raceme of small white 6-merous flowers. Perianth 

 rotate. Filaments subulate; anthers rounded or oblong, versatile, 

 introrse. Ovary ovate; style short, thick, 3-lobed. Fruit a globose 1 

 3-seeded berry. 



1. V. amplexicaulis (Nutt.). Eootstock simple, stout: stem 1^3 

 ft. high, somewhat pubescent: leaves ovate-oblong or elliptical, 37 in. 

 long, sessile, amplexicaul: panicle of short racemes dense, short-pedun- 

 cled, 2 in. long: perianth segments oblong-lanceolate, less than a line 

 long: broadly subulate filaments both longer and broader than the 

 perianth-segments : berry light red and with dots of dark red, usually 1- 

 seeded: seed whitish, 1^ lines thick. Woods of the Coast Kange. 



2. V. sessilifolia (Nutt.). Eootstock slender, branching, the plants 

 thus forming close colonies covering the ground extensively : stem 1 2 

 ft. high, flexuous: leaves bright green, glabrous, 26 in. long, acute or 

 acuminate, sessile, clasping, more or less plicate and furrowed (strongly 

 so when young): raceme loose, flexuous, the spreading pedicels 27 lines 

 long: perianth segments 24 lines long; stamens half as long: berry glo- 

 bose, red, 1 3-seeded: seeds brown. Plentiful on moist northward 

 slopes in thickets. 



12. UNIFOLIUM, Brunfels. More diminutive herbs, with only 1- 3 

 cordate leaves. Raceme short, simple, but the flowers often 2 or 3 

 together at a node. Perianth segments and stamens 4. Ovary 2-celled; 

 stigma 2-lobed. Otherwise like the preceding genus. 



1. U. dilatatum (Nutt,). Glabrous ^ 1 ft. high, herbage deep 

 green, not glaucescent, the 2 or 3 leaves 2 5 in. long, ovate to subreni- 

 form-cordate, with deep sinus and rounded lobes, the petiole 2 in. long 

 or more: perianth segments oblong-obovate, deflexed; stamens shorter 

 than these. Woods of Marin Co. and northward. 



13. DISPORUM, Salisb. Eootstocks short, erect. Boots fibrous. 

 Stems branching. Leaves alternate, sessile, thin, many-nerved. 

 Flowers 1 3 or more at the ends of the leafy branches. Perianth cam- 

 panulate, of 6 white or greenish distinct segments. Stamens 6; fila- 

 ments distinct filiform; anthers oblong, attached within above the base. 

 Ovary ablong or ovate; style slender, entire or with 3 short spreading 

 stigmas. Fruit a red berry, 3 6-seeded. 



1. I). Menziesii (Don.), Britton. Somewhat woolly-pubescent: stems 

 1 3 ft. high: leaves ovate to ovate-lanceolate, narrowly acuminate, 

 rounded or subcordate at base, 25 in. long: fl. 15; perianth whitish,
