ORDER CI. LILIA'CEJE. (LILY FAMILY.) 

 Herbs, distinguished as a whole by their regular and sym- 

 metrical flowers, having a 6-leaved perianth (but 4-leaved in one 

 species of Smilacina) free from the usually 3-cellud ovary, and as 

 many stamens as divisions of the perianth (one before each] with 

 2-celled anthers. Fruit a pod or berry, generally 3-celled. The 

 outer and inner divisions of the perianth coloured alike, except 

 in the genus Trillium. (See Part L, sections 82-87, for descrip- 

 tion of typical plants of this Order.) 



Synopsis of the Genera. 



* Leaves net-veined, all in one or two whorls. The stem otherwise naked, 



rising from a fleshy rootstock. Styles 3. 



1. Tril'lium. Leaves 3, in a whorl at the top of the stem. Divisions of the 



perianth in 2 sets, the outer green, the inner coloured. (See Parti., 

 sections 85 and 86.) 



2. Mede'ola. Leaves in 2 whorls, the lower near the middle of the stem, and 



consisting of 5-9 leaves, the upper of (generally) 3 small leaves, near the

 Stem smooth and glaucous, from a coated bulb. 



4. Tofield'ia. Flowers small, perfect, greenish-white, in a terminal raceme 



or spike, which, however, develops from above downward ; the pedicels 

 in clusters of 3, from little involucres of 3 bracts. Pod triangular.

 Leaves 2- ranked, equitant. 



* * * Leaves straight -veined, but broad (not grass-like), alternate. Stem 



//VIM a rootstock or fibrous roots, at all events not from a bulb. Style 

 one at the base, but more or less divided into 3 above. 



-H- Perianth of completely separate y//-<v.s' (polyphyUatot), 



5. Uvula'ria. Stem leafy, forking above. Flowers yellow, at least an inch
