 commonly flat or thin-mar gintd. 



7. AMIANTHIUM. Flowers perfect, mostly in a simple raceme. Perianth white, 



the oval or obovate spreading divisions without claws or spots. Filaments 

 long and slender. Seeds wingless, 1-4 in each cell. Leaves chiefly from the 

 bulbous base of the scape-like stem, linear, keeled, grass-like. 



8. STENAN T1IIUM. Flowers polygamous, in panicled racemes on a leafy stem. 



Perianth white, with spreading and not spotted lanceolate divisions tapering 

 to a narrow point from a broader base, which coheres with the base of the

9. VERATlil'M. Flowers polygamous, in panicled racemes. Perianth greenish 



or brownish, its obovate-oblong divisions narrowed at base, free from the 

 ovary, not spotted. Filaments snort. Seeds rather numerous, wing-margined. 

 Leaves broad, many-nerved. Base of the leafy stem more or less bulb-like, 

 producing many long white roots. 



10. MELANTHIUM. Flowers polygamous, in racemes forming an open pyramidal 



panicle. Perianth cream-colored, turning green or brownish with age, per- 

 fectly free from the ovary, its heart-shaped or oblong and partly halberd- 

 shaped widely spreading divisions raised on a claw and marked with a pair 

 of darker spots or glands. Filaments short, adhering to the claws of the 

 perianth, persistent. Seeds several in each cell, broadly winged. Leaves 

 lanceolate or linear, mostly grass-like. Stem roughish-downy above, its 

 base more or less bulbous. 



11. ZYGADENUS. Flowers pefect or polygamous, in a terminal panicle. Peri- 



anth greenish white, its oblong or ovate widely spreading divisions spotted 

 with a pair of roundish glands or colored spots near the sessile or almost 

 sessile base. Stamens free from and about the length of the perianth. Leaves 

 linear, grass-like ; stem and whole plant smooth. 



III. BELLWORT FAMILY; with alternate and broad not 

 grass-like parallel-veined leaves : stem from a rootstock or from 

 fibrous roots, branching and leafy : style one at the base, but 3-cleft 

 or 3-parted. Fruit a pod, few-seeded. Anthers turned rather 

 outwards than inwards. Perianth of 6 almost similar and wholly 

 separate pieces, deciduous. Not acrid nor poisonous. Plants inter- 

 mediate between the preceding groups and the next. 



12. UVULARIA. Flowers solitary or sometimes in pairs at the end or in the forks 



of the forking stem, drooping, yellowish; the perianth rather bell-shaped 

 and lily-like, its divisions spatulate-lanceolate, with a honey-bearing groove 

 or pit at the erect narrowed base. Stamens short, one at the base of each 

 division: anthers linear, much longer than the filaments. Pod triangular or 

 8-lobed, loculicidal from the top. Seeds thick and roundish.
