Eriocapitella tomentosa
Eriocapitella tomentosa, a species of flowering plant in the buttercup family Ranunculaceae, is native to Asia. The specific epithet "tomentosa" means "thickly matted with hairs, tomentum (padding)". In Chinese, a common name is da huo cao (大火草), which means "big fire grass" or "great fireweed". Taxonomy. "Eriocapitella tomentosa" was described by Maarten J. M. Christenhusz and James W. Byng in 2018. Like other members of genus "Eriocapitella", "E. tomentosa" was formerly a member of genus "Anemone". In particular, the basionym "Anemone japonica" var. "tomentosa" and the synonym "Anemone tomentosa" were described in 1889 and 1933, respectively. "Eriocapitella tomentosa  is often confused with E.  vitifolia". Indeed, the former was thought to be a variety of the latter for over 100 years. Specifically, the names "Anemone vitifolia" var. "tomentosa" and "Eriocapitella vitifolia" var. "tomentosa" , both of which are synonyms of "Anemone tomentosa", were described in 1904 and 1941, respectively. Ecology. "Eriocapitella tomentosa" along with four other taxa ("E. hupehensis", "E. japonica", "E.  vitifolia", and "E." × "hybrida") are known as fall-blooming anemones. In its native habitat, "E. tomentosa" flowers from July to October.
