A chromatographic and cytological study of Dryopteris dilatata in North America and eastern Asia
A chromatographic analysis of the phloroglucinol derivatives of 123 collections of Dryopteris intermedia Gray (2x), D. assimilis S. Walker (2x) from western North America, D. "dilatata" from eastern North America (2x), D. "austriaca" from Japan and Kamchatka, "Aspidium dilat...
