362 CLVI. LILIACE.E. (J. D. Hooker.) [Trillium. 



Stem 8-12 in. Leaves 2-3 iu. broad and long or narrower. Peduncle - in. 

 Flowers f-1 in. diarn. ; filaments flat, rather longer than the linear anther. Style 

 very short. This, which differs from the American and Japanese T. erectum chiefly 

 in the longer filaments, will (with others) prove, I expect, a form of that variable 

 species.
