Museum Botanicum Lugduno-Batavum 1: 310 ( Blume 1851) [“ 1849–1852 ”]. – C. heterophylla var. sieboldiana (Blume) A.DC., Prodromus Systematis Naturalis Regni Vegetabilis 16 (2): 130 ( Candolle 1864). – C. rostrata var. sieboldiana (Blume) Maxim. , Bulletin de l’Académie Impériale des Sciences de St.-Pétersbourg 27: 538 ( Maximowicz 1881). – Original citation: “Siki-fasibami s. Tsumo-fasibami japonice. Sponte in japonice montibus Nikoo fide speciminis Herb. von Siebold.” – Type: Japan, [locality unknown], P.F. von Siebold. 2 or 16 (lecto-, designated here: upper plant of L0366714!). – Additional type material: Japan, [unclear locality], P.F. von Siebold. 2 or 16 (syn-: lower plant of L0366714!). – Note: there are actually two collections on the sheet, the upper one with fruits and a lower one without. There are four labels on the specimen. A first label is attached to the upper specimen containing the Japanese name in Katagana signs> [shi] * [ki] ^ [ha]> [shi] ^ [ha, also to be pronounced as ba] ミ [mi], literally “lucky hazel”. A second label is a Leiden label with the Latin name C. sieboldiana and transcription of the Japanese name “Si-ki-hasi-bami”. A third label is Siebold’s original in the lower left with the number 16 and the Japanese name in Katagana signs " [tsu] ¹ [no] ^ [ha]> [shi] ^ [ha, also to be pronounced as ba] ミ [mi], literally “horned hazel”. The fourth label bears the number 2, locality as in the protologue, and the Latin and the Japanese name. It is unclear which label with a number corresponds to which specimen or where the “no. 2” comes from, therefore the lectotype citation here is given rather crudely. The “f” in the transcriptions in the protologue is easily explained as misreading of the “h” of the original label in the Kurrent handwriting, which is similar to the “f”. The indument of the tubular involucre varies among the different type specimens of the synonyms. Two basic forms can be found in different described varieties of C. sieboldiana . The involucre is glabrous or very finely hairy ( C. sieboldiana var. mitis and C. hallaisanensis ), while it consists of dense bristly trichomes in C. sieboldiana var. brevirostris , C. sieboldiana var. mandshurica , and C. sieboldiana var. sieboldiana . The type of C. hallaisanensis differs from C. sieboldiana var. mitis in having apically coarsely irregular serrated leaves, like C. sieboldiana var. mandshurica . To the present authors’ knowledge, there is no critical revision or phylogeographic analysis existing that has tested the significance of the involucre indument.
