Systematic Studies of Asian Saussurea (Asteraceae) III. Saussurea fuboensis, a New Species from the Southernmost Part of Tohoku District, Northern Japan

Abstract

A new species, Saussurea fuboensis Kadota, is described from the southern part of Tohoku District, northern Japan. S. fuboensis is related to S. nikoensis Franch. & Sav. but is distinguished from it by having arachnoid, cylindrical involucres less than 1 cm in diam., throats of florets 1 mm long, narrowly winged stem, broadly ovate leaf blades, ascending involucral phyllaries, and narrowly ovate, outer involucral phyllaries 2 mm wide at base. S. fuboensis grows in meadows and along Pinus pumila - Alnus maximowiczii scrubs in the alpine zone of the southernmost part of the Owu Mountain Range, Tohoku District.
