CELASTRACEAE 



Euonymus 



ing shrub; fls. V-VI; fr. (red aril) in terminal clusters, X-XI. Eastern Asia;

 IX-X. Central and western China; locally in An., Che., Ki., Ku. Thickets. 



3. Celastrus orbiculata Thunb. (C. articulata Thunb.) W$cM (Nan She T'eng; 

 Southern Snake-vine) (R.M. 562). Climbing shrub; fls. greenish, IV-V; fr. orange,

Celastrus articulata (Thunb. Fl. Jap. (1784) 97) is now shown to be a typographical error. 

 The correct name, as intended by Thunberg, appears in the systematic list at the beginning 

 of the volume, p. xlii, C. orbiculata. For explanation of this case, and of the use of the 

 masculine ending of the species name, since the genus name was transferred from the Greek 

 by Linnaeus in that form, see discussion by H. K. Airy Shaw in Bot. Mag. 158 (1935) t. 9394.
