HaJ). Etorofu, at Shibetoro. 



The plant approaches nearer in all its characters to the European P. media than to our 

 P. minor or rotundlfolia. The stamens are erect, and shorter than the nearly straight 

 stout style; the stigmatic lobes are minute and erect, and are provided with a distinct 

 rino" around their base; and the anthers are not narrowed below the pores. The bracts 

 are lai'ger than in P. minor, and are longer than the pedicels. A specimen collected by 

 C. Wright at Simoda is in bud. Compared with my plant the style is longer and dcflexed, 

 and the anthers are larger, even in the bud, and somewhat narrowed beneath the oi^en- 



ings.
