Takeda, 1. c., has indicated the distinctive characters of this 
segregate of M. maritima. However, his description of the floral 
parts does not wholly coincide with my own observations. It reads: 
“ corolla magna, plus 10 mm. longa. . . . Stamina anthero 2 mm. 
longo, filamentis aequanti. Stylus inclusus, 8 mm. longus, stami- 
nibus superans.’’ An examination of the material cited has given 
the following data. Corolla 8-10 mm. long; filaments nearly 
equalling to twice longer than the anthers; style often slightly 
exserted, 7—9.5 mm. long. The same class of information for M. 
maritima is: corolla 4-6 mm. long; filaments about three times as 
long as the anthers; style 44.5 mm. long, shorter than the sta- 
mens. The long style and large corolla are constant characters of 
all the specimens seen from Japan and adjacent Asia, while the 
much smaller corolla and shorter style are features of material from 
Europe, America, and Northeastern Siberia. If it were not for the 
facts that in all specimens here included in M. asiatica the stamens 
are inserted near the top of the corolla-tube just as in M. maritima 
and that the style is uniformly longer than the stamens, one would 
one would be inclined to regard the latter character as a dimorphic 
phenomenon since dimorphism in some form is not rare in the 
family. Mertensia alpina, for instance, exhibits a sort of dimor- 
phism, but specimens from the same region show both long and 
short styles in correlation with low and high stamen-insertion. 
Moreover, in the English edition of Knuth’s Handbook of Flower 
Pollination, iii. 138 (1909), we learn that in M. maritima “ the 
anthers being at the same level as the stigma automatic self-polli-
