LILY FAMILY. 433 



11. UVULAKIA. Stem 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 3-6-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, 



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. COLCHICUM. Perianth resembling that of a Crocus. Stamens borne on the throat 



of the long-tubular perianth. Styles very long. 



* * Perianth without an evident tube, of 6 distinct or almost separate divisions. 



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



H- Leaves all at the base of the stem, the latter sometimes bracteate. 



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



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

 Pod 3-lobed ; cells many-seeded. 



17. TOFIELDA. Flowers perfect, in a close raceme or spike, mostly with a small 3-bracted 



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

 vate, 3-nerved. Styles awl-shaped. Capsule 3-angled, the cells many-seeded. 

 Tufted, from creeping rhizomes. 



-H- ++ Stems very leafy. 



18. CHAM^ELIEIUM. Flowers dioecious or mostly so. Perianth of 6 small and narrow 



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



19. XEROPHYLLUM. 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.
