This species has been confused with the Japanese species Buckleya lanceolata (Siebold & Zuccarini) Miquel, which differs by having bracts longer, ca. 3 × as long as fruit, leaves more markedly caudate, and indumentum dense and often multicellular.

The fruit contains starch. The fresh leaves and bark are poisonous.
