Dear Gurcharan Sir, Thanks for asking this question. I found the protologue of S. japonica today that states:
Solidago japonica Kitamura sp. nov. Ab illa involucre angustiore 5 mm. longo, squamis imbricates apice obtusis, extimis multo-brevioribus ovatis circ. 1 mm. longis distinguenda. Typus- Prov. Yamashiro: Mt. Hiei (X. 1920 G. Koidzumi- in Herb. Univ. Imp. Kioto). Nom. Jp. Akino-Kirinso- Somokuzusetsu ed. Makino. IV. P. 1022. fig. Whereas the flora of Japan says: ssp. virgaurea differs in having broadly campanulate involucres and densely pilose achenes. I would take the photographs of the achenes and upload here soon. Best regards, Ritesh. --
