﻿ON THE BOTANY OF JAPAN. 395 



to it, under the name of Heteropappus incisus, Sieb. & Zucc, he has wrongly referred 

 both Ksempfer s and Thunberg's plants as synonymes. 



Lessing's Aster Japoniciis, with a dubious variety, I must refer to Erigeron* It is 

 the Japanese analogue of the Oalifornian E. glaucum. 



The form of Solidago Yirgaurea common at the Loo Choo Islands and Hong Kong 

 (var. leiocarpa = Amphirepis leiocarpa, Benth.) was likewise found in the southern 

 part of Japan. It quite resembles European forms of the species, except in the 

 glabrous achenia. This character it shares with 8. thjrsoidea, Meyer [S. leiocarpa, 

 DC), a subalpine plant in Eastern North America, and probably another form of 

 S. Virgaurea. 



None of our collectors met with De CandoUe and Zuccarini's Poropthyllum Japoni- 

 cum ; which is surely not of this genus at all, but a Gynura, — most probably (since, 

 according to Siebold, the plant was imported from China) G. pinnatifida, DC, the 

 Cacalia pinnatifida of Loureiro. I presume there are no Asiatic species of the genus 

 PorophgUum. 



The collection affords an addition to the genus Erythrockcste, Sieb. & Zucc, but 

 only a single specimen of it.f Cacalia hastata, Linn., the North Asian and Eastern 

 European analogue of our Eastern American C. suaveolens, was found at Cape Soya, 

 along with Senecio palmatus, Pall. ; also, on the sea-shore, S. Pseiido-Arnica, a subarctic 

 species of both shores of America. 



Besides Cirsium Kamtschaticmn at the north, and C. Japonicum, DC, farther south, 

 there are in the collection specimens of a Thistle related to C. eriophorum, and which, 

 indeed, I should take for Thunberg's Carduiis eriophorus, if De Candolle had not referred 

 that to his C. Japonicum, upon the authority of a Thunbergian specimen. It cannot 

 well be C. lap)pacemn ; so I am obliged to consider it new. J
