LILT FAMILY. 433 



11. U V TTLARIA. Btem terete. Flowers solitary, drooping, yellowish ; the perianth nar- 



rowly bell-shaped and lily-like, the sepals spatulate-lanceolate and acuminate, 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 

 truncate, 3-lobed, loculicidal from the top. Seeds thick and roundish. Leaves per- 

 foliate. 



12. OAKESIA. Stem angled. Flowers opposite the leaves (by the growth of the stem), 



the segments not acuminate. Capsule thin, elliptical, acutish at each end, sharply 

 3- winged and tardily dehiscent. Leaves sessile. 



IV. TRILLIUM SUBFAMILY. With netted-veined leaves 

 all in one or two whorls on an otherwise naked stem, which 

 rises from a fleshy rootstock ; styles or sessile stigmas 3, sepa- 

 rate down to the ovary. Fruit a berry. 



13. TRILLIUM. Perianth of 3 green persistent sepals, and 3 colored petals ; the latter at 



length withering away after flowering, but not deciduous. Anthers linear, adnate, 

 on short filaments, looking inwards. Awl-shaped styles or stigmas persistent. 

 Ovary 8-6-angled. Berry purple or red, ovate, many-seeded. 



14. MEDEOLA. Perianth of 6 oblong and distinct nearly similar pieces, recurved, decidu- 



ous. Anthers oblong, shorter than the slender filaments. Stigmas or styles long 

 and diverging or recurved on the globular ovary, deciduous. Berry dark-purple, 

 few-seeded. 



V. MELANTHIUM SUBFAMILY. With alternate and 

 parallel-veined leaves ; stem simple, at least up to the panicles ; 

 and flowers often polygamous, sometimes dioecious ; styles or 

 sessile stigmas 3, separate down to the ovary. Fruit a pod. 

 Anthers almost always turned outwards. Perianth withering 

 or persisting, not deciduous, the 6 parts generally alike. 

 Mostly acrid or poisonous plants, some used in medicine. 



* Perianth with a long tube rising directly from a thin-coated solid bulb or corm ; 

 anthers •2-celled. Stemless. 



15. OOLCHICITM. Perianth resembling that of a Croons. Stamens borne on the throat 



of the long-tubnlar perianth. Styles very long. 

 • * Perianth without an evident tube, ofG distinct or almost separate divisions. 

 +- Anthers 2-celled, short ; flowers in a simple raceme or spike ; pod loculicidal. 

 4+ Leaves all at the base of the stem, the latter sometimes bracteate. 



16. HELONIAS. Dowers perfect, in a short dense raceme, lilac-purple, turning green in 



fruit ; the divisions spatulate-oblong, spreading. Filaments slender ; anthers blue. 

 Pod 8-lobed ; cells many-seeded. 



17. TOFIELDA. Flowers perfect, in a close raceme or spike, mostly with a small 8-bracted 



involucre beneath. Perianth white or greenish, the sepals concave, oblong or obo- 

 vate, 8-nerved. Styles awl-shaped. Capsule 8-angled, the cells many-seeded. 

 Tufted, from creeping rhizomes. 



++ ++ Stems very leafy. 



18. CHAM-SLIEITJM. Flowers direcious or mostly so. Perianth of 6 small and narrow 



white pieces. Pod ovoid-oblong, many-seeded. Spike or raceme slender. 

 i9. XEROPHTLLTJM. Flowers perfect, in a compact raceme, white ; the divisions oval, 

 sessile, widely spreading, naked. Filaments awl-shaped. Pod globular 8-lobed, 

 with 2 wingless seeds in each cell.
