mistakes will hereafter occur in any botanical publication. There 
seem still to remain some plants misreported from the Far East, 
which induces me to offer here some remarks from the phyto- 
geographical as well as from the systematic point of view. 
Under the name of P. fragiformis several different species have 
been reported. Also various views have been put forward with 
regard to the limit and relationship of P. fragiformis. Maximowicz 
and Hooker suggest that P. grandiflora, P. gelida, and P. fragiformis 
are the same species. As Th. Wolf states in his monograph (p. 
510), P. fragiformis is often confused in herbaria with P. grandiflora, 
P. gelida, and P. villosa. Professor Miyabe in compiling the flora 
of the Kurile Islands at the Gray Herbarium studied these easily 
confused species and in his paper pointed out the different 
characters of the plants. He lays weight on the nature of the 
achene and regards those four plants as distinctive species, 
considering P. grandiflora and P. gelida as forming one group, 
ile P. fragiformis and P. villosa form another. Th. Wolf 
discusses these plants and has thoroughly cleared up the previous 
misconception, so that there seems to be no need to add any further 
remark, 
I wish to discuss here, however, the four other species known as 
P. fragiformis. The confusion is not unimportant from the phyto- 
geographical point of view and will cause no little inconvenience if 
left untouched. 
One of four plants reported as P. fragiformis is the true species. 
Descriptions of this can be found in Lehman’s monograph as well 
as in Th. Wolf’s recent work, and also a fairly good habit-figure in 
Lehman. 
Potentilla fragiformis, Willd. 
1. Radical leaf.—2. Petal_—3. Calyx at time of flowering.—4. The same in 
fruit.—5. Carpel (72).—6. Achene (7). 
In the Far East this plant occurs in Amurland and the Ochotzk 
region, but not in any part of Japan. © 
The second one is a species closely allied to the preceding, but 
distinct and as it has been left unnamed, I propose to call it
