Also known as: sieboldiana, sieboldianum
A commemorative epithet honouring Philipp Franz von Siebold (1796-1866), the physician whose collections carried a great many Japanese garden plants into Europe. The -ianus adjective agrees with its genus, so a change of ending signals gender rather than a different botanist. Appears as sieboldianus (masculine), sieboldiana (feminine), or sieboldianum (neuter).
Etymology
From the surname Siebold with the Latin adjectival suffix -ianus, meaning "of Siebold."
Example
“Eleutherococcus sieboldianus 'Variegatus' (variegated five-finger aralia) and Hosta sieboldiana (Siebold's hosta) carry the same honorific under different genders.”
