Aster Piccolii is a very interesting as well as handsome 
plant, being referable to the much misunderstood Chinese 
genus Hisutsua, which was founded by De Candolle (Prodr, 
xi. 44) on Matricaria cantoniensis, Lour., an epappose 
plant, erroneously but doubtfully referred by its author to 
the tribe Senecionider. Hisutsua was next taken up by 
Hooker & Arnott (Fl. Bot. Beech. Voy.,” p. 265), 
who referred to it as H. serrata, a plant which belongs 
to Blume’s genus Asteromoca. Bentham followed, in the 
Flora of Hong Kong,” p. 174, where he brings together 
as synonyms of H. cantoniensis, two very different plants, 
H. serrata, H. & A., and Asteromoea indica, Blume, referring 
all three, erroneously, I think, to the N. American genus 
Boltonia (as B. indica, Benth.). With regard to Asteromoea, 
it was founded by Blume on Aster indicus, L., a plant 
differing from Aster and Hisutsua in its imperfect pappus. 
It has been referred by Schult. Bip. to the genus Calimeris 
of Nees, which does not differ from Aster; quite 
recently it has been rightly regarded as a section of the 
latter genus by Mr. Makino in the Tokyo Botanical Maga-
