Hara (1965: 327) Lectotype (designated here) :— NEPAL [as NEPALIA], 1821, Wallich Cat. no. 4309a ( K , K001038681 ) ( Fig. 2 ); isolectotypes : [ A , A00049675 , BM , BM000838984 , C , CAL , CAL0000066376–77 , 81, CGE , CGE00080099 , E , E 00301194– 96 , GH , GH02462084 , GH, GH02463721 , MICH , MICH-V-1104444 , NY , NY00337331 , OXF , OXF00140908–09 , P , P00499879 , S , S11-17212 , W , W0215374 ]. Notes: Celastrus rufa [ rufus ] is based on two gatherings, “ Common in the forests of the valley of Nipal [ Nepal ] and “I have also found it at Tambakan [ Indonesia ]” (Wallich in Roxburgh 1824 ). We traced a total of 20 Wallich collection of C. rufus from Nepal housed at A, BM, CAL, C, CGE, E, GH, K, MICH, NY, OXF, P, S and W that all regarded here as syntypes ( McNeill 2014 ). But our efforts to trace the Tambakan specimens were all in vain [perhaps Wallich might have observed the plant at Tambakan but might not have collected it. If he had collected, then he would have included that gathering in his catalogue]. The specimen at K (K001038681) and CAL (CAL0000066376) maintained with flowers, fruits, and the original field label in Wallich’s handwriting, of which the former specimen is selected here as lectotype .
