1924] NAKAI, ARALIACEAE IMPERII JAPONICI 35 



praesertim si molis tarn est incommodae, et praeterea, quia a Miquelio, qui spec, 

 auth. examinata, sub silentio praeteriter, nostro P. repenti desumta est." (See 

 M6L Biol. vi. 266-267 [1867]). 



C. A. Meyer remarks: 



"Erst v. Siebold, dem wir so viel ftir die Kenntniss Japan's zu verdanken haben, 

 machte auf die Verschiedenheit dieser Pflanzen, sowie des japanischen Ginschen, 

 aufmerksam, und Fr. Nees von Esenbeck sah sich veranlasst, zwei Arten anzuneh- 

 men, den amerikanischen Panax quinquefolius und den asiatischen P. Schinseng; 

 diese letztere Art umf asst, nach des Verf assers Ansicht, den mandshurisch-chinesis- 

 chen und den japanishen Ginschen, so wie den nepalischen P. Pseudo-ginseng." 

 (See Bull. Phys.-Math. Acad. Sci. St. PStersb. i. 339 [1824]). 



Though Meyer's name Panax japonicum might possibly have been 

 derived from Siebold's Panax quinqucfolium b. japonicum, his description 

 is based entirely on the figure of Nees, since he says "Plantain non vidi, 

 sed ex icone speciem omnino distinctam esse credo," and Siebold did not 

 have a figure, while Nees von Esenbeck published an excellent colored 

 plate in his Icones Plantarum Medicinalium. According to Meyer's 

 description "rhizomate repente, fibris lateralibus fusiformibus; squama 

 decidua ad basin caulis; foliolis 5 oblongis acuminatis profunde serratis" 

 the plant cannot be any other than this species. Eliminating the synonym 

 P. quinquefolium b. japonicum Siebold, the name P. japonicum becomes 

 the correct name for this species and Panax repens becomes its synonym. 

 So far as I know there is no yellow-fruited Panax Ginseng. I think 

 Siebold made his note from memory and mistook Panax japonicum and 

 his specimen of Panax schin-seng for the same species.
