11. YAGNERA, 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 gloljose 1 — 

 3-seeded berry. 



1. Vt amplexicaulis (Nutt.). Rootstock simple, stout: stem 1J^ — 3 

 ft. high, somewhat pubescent: leaves ovate-oblong or elliptical, 3—7 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 Range. 



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

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

 ft. high, flexuous: leaves bright green, glabrous, 2 — 6 in. long, acute or 

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

 so when young) : raceme loose, flexuous, the spreading pedicels 2 — 7 lines 

 long: perianth segments 2 — 4 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. dilsitatum (Nutt.). Glabrous Y % — 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. Rootstocks short, erect. Roots 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. D. Menziesii (Don.), Britton. Somewhat woolly-pubescent: stems 

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

 rounded or subeordate at base, 2 — 5 in. long: fl. 1 — 5; perianth tehitish, 

 almost funnelform, the segments being erect, nearly 1 in. long; style more
