1. TRILLIUM, L. THREE-LEAVED NIGHTSHADE. 



Sepals 3, lanceolate, spreading, herbaceous, persistent. Petals 3, larger, 

 withering in age. Stamens 6 : anthers linear, on short filaments, adnate, in- 

 trorse ; the cells opening down the margins. Styles (or rather stigmas) awl-

 inner side. Ovary 3 - 6-angled. Berry ovate, 3-celled (purple or red). Seeds 

 horizontal, several in each cell. Low perennial herbs, with a stout and sim-

 at the summit a whorl of 3 ample, commonly broadly ovate, more or less ribbed 

 but netted-veined leaves, and a terminal large flower ; in spring. (Name from 

 triiix, triple; all the parts being in threes.) Monstrosities are not rare with 

 the calyx and sometimes the petals changed to leaves, or with the parts of the 

 flower increased in number. 

 1 . Flower sessile in the bosom of the leaves, erect : petals varying from, spatulate 



to lanceolate, 1'- 2' long, little exceeding the sepals, withering-persistent (stems
