from the American T. erectum, ovatum, and grandijiorum, in its broader petals and 

 shorter stigmas. The tip of the ovary is dark purple in color, and the petal is always 

 white. Trillium TsclionosTcii, Max., which grows also in Yezo, has the ovary greenish 

 throughout. Its petals are white with a slight reddish tinge, and the anther is about as 

 long as the filament. These two species have been much confused in Japan.

The species is distributed through Europe and northern Asia to Kamtschatka and ad- 

 jacent islands, and in Japan under different varieties and forms. According to Baker, 

 as V. Eschsclwltzii and V. viride in North America.

My specimens agree exactly with the Saghalin plant collected by Schmidt. The cymes 

 are terminal and suberect; flowers few in a cluster, also suberect. They agree well 

 with Fries's J. articulatus, var. subatratus, which is placed under J. lampocarpus, 

 Ehrh., by Buchenau. The species is very widely distributed through Europe, northern 

 Africa, temperate Asia and eastern North America.
