 Dr. Gray, in his notes on the Japanese plants collected in the Perry expedition, called 

 our attention to a close affinity of the Simoda plant to Aster unalaschensis. Later, he 

 made a remark on a larger and less hairy form collected by J. Small at Cape Shiri- 

 yazaki in the strait of Tsugaru, that it is the Japanese analogue of the Californian Erig- 

 eron glaucus. Examination of these original specimens in connection with my own 

 collected on the eastern coast of Yezo and in Shikotan, shows a distinct similarity be- 

 tween them in all their important characters. No two specimens, however, are alike in 

 the degree of the pubescence on their stalks and involucres. The Shikotan specimen 

 is, for instance, almost smooth in its involucre, being simply ciliate on the T margins ; while 

 in the Simoda plant it is densely villose, though not lanose. There is also some difference 

 in the color of the pappus. All the specimens collected in the main island of Japan have 

 a reddish, cinnamon-colored pappus; while those of the northern islands have a light, 

 yellowish-brown one. But these differences are also seen to occur among a large num- 

 ber of the American specimens of E. salsuginosus in the Gray Herbarium. 



The specimens collected at the Shiriyazaki have a general character just about inter- 

 mediate between E. glaucus and E. salsuginosus. My Kurile and Yezo specimens, on 

 the other hand, correspond very well with the typical salsuginosus; and through these 

 northern plants one may safely refer those growing in the main island to the species un- 

 der consideration, probably as its Japanese variety. 



Distrib. Middle and northern Japan, the Kurile Islands to Alaska, thence south- 

 ward along the higher mountains to California, Utah and New Mexico.
