UNIFOLIUM 
Low; rhizomes slender. Stem simple. Leaves wide, few, simple, alternate, peti- 
oled (ours) or- sessile. Flowers small, white; in a terminal minutely-bracted raceme 
or panicle; pedicels often 2—4 together. Perianth-segments 4, distinct, equal. Sta- 
mens 4, on base of perianth; anthers introrse. Ovary sessile, 2—3-celled; cells 2- 
ovuled; style 2-lobed or -cleft. Fruit a berry, globose. Seeds I1—4. (L. unus=I, 
folium—leaf; because sterile plants usually have but | leaf.) W.C. (V. dilatatum.) 
U. bifolium kamtschaticum Pip. (Wild Lily-of-the-Valley) 
DISPORUM (Prosartes) FAIRY-BELLS 
Rhizomes runner-like; stem scaly-bracted below, leafy above, branched. Leaves 
wide, sessile, alternate, somewhat oblique. Flowers rather small, in a terminal few- 
flowered umbel. Perianth narrowly campanulate; segments 6, distinct, deciduous. Sta- 
mens 6, hypogynous; anthers extrorse. Ovary sessile, 3-celled; cells mostly 2-ovuled; 
style slender, deciduous; stigmas | or 3. Fruit a berry. Seeds globose, 3—many. 
(Gk. disdouble, spora—seed; because the cells of the ovary are 2-ovuled.) 
A. Leaves rounded or slightly cordate at base, not clasping; stigma 3-cleft. 
B. Plant much-branched; perianth-segments |2—-22 mm. long; stamens about 2/3 
as long as the perianth; berry short-beaked, nearly smooth except at beak, 3—6- 
seeded. W.C. (D. menziesii.) 
D. smithii Pip. 
BB. Plant sparingly branched; perianth-segments 12—-14 mm. long; stamens 
about equaling the perianth; berry not beaked, papillose, 3—18-seeded. E. (D. 
trachycarpum. ) D. majus Brit. 
AA. Leaves mostly cordate at base (except D. trachyandrum), at least the lower moally 
clasping; stigma entire. 
C. Leaves averaging about 3.7—-5 cm. long; stamens more than 2/3 as long as 
the perianth; filaments elongated, longer than the anthers. 
D. Leaves long-acuminate; pedicels woolly-pubescent; stamens about 11/2 times 
as long as the perianth; berry acutish. W. C. E. 
D. oreganug B. & H. , 
DD. Leaves acute or short- acuminate; pedicels not woolly-pubescent; stamens 
about equaling or shorter than the perianth; berry beaked or obtuse. 
E. Leaves deeply cordate at base; stamens about equaling the perianth; ovary 
pubescent, obtuse. U. 
D. hookeri B. & H. 
EE. Leaves rounded to cordate at base; stamens about 2/3 as long as the 
perianth; ovary glabrous, with short stout beak. U. 
D. trachyandrum B. & H. 
CG Leaves averaging about 2.5 cm. long; stamens 1/4 as arlene as the perianth; 
filaments very short, much shorter than the anthers. U. 
D. parvifolium B. & H.
