FLORA OF THE KUUILE ISLANDS. 215 



pubescence. The only points ol' diflerence between them, which I can tind in the few 

 specimens before me, ai-e that the sepals are perfectly smooth on both sides in the Jap- 

 anese plant, and that the peduncles are shorter than the leaves. The ovaries are still 

 too yomig to show decidedly whether tliey are sessile or stipitate. They are covered 

 witb silvery appressed hairs; and the styles are elong-ated, cylindrical, smooth and erect. 

 Doubtless the plant is much more closely related to A. umhrosa than to any other species. 

 The character of its ripened carpels would settle the point, whether it is to l)e considered 

 as a variety of that species or as distinct.

Tiie plant is closely I'elated thi'ongh some of the allied species growing on the conti- 

 nental side of Asia to R. j)ennsijlvanicus of jS^orth America, of which, by a high author- 

 ity, it is considered a vailety. 



However variable onr plant is in many of its minor characters, incident to its great 

 range of stations from the roadside ditch to the cold wet mountain woods, extending from 

 the Loo Choo Islands to the Kiiriles, yet there are some important characters which are 

 constant at least within our insular limits. In these important characters, it differs dis- 

 tinctly from the typical Ranunculus pennsylvanicus. 



In the latter, the akenes are provided with short, stout, and straight or slightly curved 

 beaks, and are arranged in oblong or cylindraceous heads; and the petals are small, not 

 sui-passing the reflexed calyx. In R. japonicus, the akenes are provided with beaks which 

 are attenuated and uncinate or subuncinate at the tip, and broad and fiat at the base; they 

 are arranged in globose heads; and the petals are larger, surpassing the recurved calyx. 

 Considering all chai'acters, our plant is more nearly related to R. Mspidus, as chai'ac- 

 terized by Dr. Gray in his Revision of the IS". Am. Ranunculi (Proc. Am. Acad, xxr, p. 

 375), than to R. peitnsi/lvanictis, L. f.
