Hab. Shikotan, in grassy places on the beach. Wtorofu, at Furubetsu. 



My Kurile specimens correspond very well with the figure and description ofLehmann 

 in his Revisio Potentillarnm. Some of the radical leaves of* the plant collected at Paru- 

 betsu attain the enormous length of 30 cm. These Leaves have in all cases only two 

 pairs of lateral Leaflets; while the smaller leaves have generally three pairs, the pairs de- 

 creasing in size toward the base. The akenes arc glabrous, and sometimes more or less 

 wrinkled; the styles subterminal, and slightly shorter than the akenes; and the receptacle 

 very hairy. 



P. fragiform/is var. japonica, A. Gray, 1 5 < >t . Jap. p. .'587, which Professor Maximowicz 

 makes a synonym of our present plant, proves according to the original specimen to be 

 P. fragarioides, var. temata. 



Distrib. Kamtschatka and adjacent islands, Saghalin, Japan, and eastern Himalaya 

 (ex Max.).

 Hub. Kurile Islands! (ex Max.). Etorofu, on rocky cliffs near Rubetsu. 

 Densely villose; stem ascending, 20-30 cm. long; radical Leaves moderately villose 

 (in small older leaves), or densely silky villose (in younger larger leaves) ; leaflets rhom- 

 bic cuneate; teeth deeply cut, oblong and obtuse; cyme generally about 5-flowered; bract- 

 lets broadly ovate and obtuse, shorter than the lanceolate or ovate-lanceolate sub-acute 

 sepals; sepals and bractlets erect in fruit, enclosing many smooth akenes which are more 

 or less distinctly keeled. 



The plants collected at Kombumori and Xemuro on the northeastern coast of Yezo 

 were equally large and were in flower. The flowers are very large, measuring about 

 40 mm. across. 



Distrib. Siberia from the Altai region to Kamtschatka ; Manchuria, northeastern and 

 middle China, Saghalin, Yezo, Aleutian Islands, Alaska to Washington Territory. 



Professor Maximowicz considers the European P. grandifora, L., and P. fragiformis, 

 Willd., of northeastern Asia, as identical, on the ground that the distinctive characters 

 based on the bractlets and the teeth of the leaves do not hold very well in every case. He 

 includes under the same species P. gelida, C. A. Mey., and also P. villosa, Pall., as its 

 varieties. A similar opinion is endorsed by Sir J. D. Hooker in his Flora of British India, 

 it, p. 357, in connection with P. gelida. 



So far as the materials at my hand allow me to judge, there seems to be a w T ell marked 

 distinctive character in the ripened akenes of these plants, which if proved to be constant 

 in all other cases would help not a little in determining their relative position. 



Potentilla grand 'if or a : — Akenes ovoid, glabrous, obtusely and obscurely ridged on the 

 margin, with four prominent curved veins running almost parallel ( f ' arcuato-rugosis " 

 of Seringe).
