Wijnands, Dirk Onno, Heniger, Johannes, Veldkamp, Jan Frederik, Fumeaux, Nicolas & Callmander, Martin W., 2017, The botanical legacy of Martinus Houttuyn (1720 - 1798) in Geneva, Candollea 72 (1), pp. 155-198 : 184

84. Polygala japonica Houtt.,

Nat. Hist. II(10): Aanwyz. Plaat. [1], 89, tab. 62, fig. 1. 1779.

Lectotypus (designated here by Veldkamp & Callmander): JAPAN: Thunberg s.n. ( G-PREL [ G00818070 ]!; isolecto-: G-PREL [ G00818071 ]!) ( Fig. 10 ).

Notes. – A specimen of original material collected by Thunberg has been located in the Japan herbarium in G-PREL. Thunberg annotated it as “ Polygala vulgaris ? Lin.” and Houttuyn as “ Polygala vulgaris Linn. vel potius Japonica, mihi. Nat. Hist. X. Stuk p. 89, Pl. 62. Fig. 1 ” with a later addendum“Thunb. Jap. p. 277”. The specimen is a very good match for the plate and is designated here as the lectotype. A corresponding specimen seems to be absent from UPS- THUNB. Another Thunberg specimen is in the Burman herbarium in G-PREL [G00818071] and should be considered as a duplicate. There are Chinese and Japanese vernacular names at the bottom of the latter sheet which were not mentioned by Houttuyn and do not seem to be in his writing.
