es following Maximowicz, they added Nagasaki as the locality 
iG. glutinosum, Fries. They were in doubt as to the existence of 
C. viscosum in the Flora of Japan, since this species is not 
enumerated in Maximowicz’s paper, and supposed — specimen 
might be a glandular form of C. vulyatum. They added to 
vulgatum another variety, var. alpinum, Bock, based on a specimen 
obtained from Mount Ibuki. Afterwards Maximowicz* published 
a new species of this genus, called C. shleapetalann from Central 
Japan, which is very interesting and is distinguished by having 
regularly 4-lobed petals. In the Flora of the Kurile Islands 
published a few years later Professor Miyabet enumerated three 
species with varieties, viz. :—C. semidecandrum, Linn. var. herbaceo- 
bracteatum, Fenzl; C. selgplet ah Linn. var. glandulosum, Koch ; 
: a 
egel; var. Fischerianum, Torr. et Gray. Of these the author 
had seen the specimens of the diene: and the last plants; others were 
inserted in his paper on the authority of the Russian botanists. In 
1898 Williams} made a revision of the Japanese species. Accord- 
ing to his opinion there are eight species known as Japanese, two of 
them being new :—C. schizopetalum, Maxim. ; C. robustum, Williams ; 
C. alpinum var. oe apis Torr. et Gr.; C. pumilum, Curtis ; 
Cc. Lanthes, Williams ; C. arvense, Linn. ; C. triviale, Link with two 
varieties namely : ypicum, Will. and glandulosum, Koch; and 
C. glomeratum, Thuill. A few years ago another new species, 
C. oxalidiflorum, was added by Makino§ to the Japanese Flora. 
No specimen of this genus had been collected in the extreme South 
of Japan, until Dr. Hayatal| reported the occurance of two species in 
the island of Formosa :—C. pilosum, Led. and C. morrisonense, 
ayata,
