124. LILIACE^, LILY FAMILY. 



Large family, known as a whole by its regular symmetrical flow- 

 ers, with perianth of 6 (in one instance of 4) -parts, as many stamens 

 with 2-celIed anthers, and a free 3-celled (rarely 2-celled) ovary. 

 Perianth either partly or wholly colored, or greenish, but not glu- 

 maceous. Flowers not from a spathe, except in Allium, &c. 

 Chiefly herbs, with entire leaves ; all perennials. The great groups 

 comprised are the following. 



A 



I. TRILLIUM FAMILY; 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, separate down to the ovary. 

 Fruit a berry. 



1. 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 f8ame;its, looking inwards. Awl-shaped styles or stig- 

 mas persistent. Ovary 3 - 6-angled. Beny purple or red, ovate, many-seeded. 



2. MEDEOLA. Perianth of 6 oblong and distinct nearly similar pieces, recurved, 



deciduous. Anthers oblong, shorter than the slender filaments. Sti^aa or 

 styles long and diverging or recurved on the globular ovary, deciduous. 

 Berry dark-purple, few-seeded. 



II. MELANTHIUM FAMILY; 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.
