Terniopsis H.C.Chao, Contr. Inst. Bot. Natl. Acad. Peiping 6(1): 2. (1949) emend. Koi et al. (2018)

  • Type species: Terniopsis sessilis H.C.Chao, Contr. Inst. Bot. Natl. Acad. Peiping 6(1): 4 (1949) possibly a synonym of Dalzellia sessilis (Chao) C.Cusset & G.Cusset (WCVP, 2021) in review.


  • Heterotypic
    • Malaccotristicha C.Cusset & G.Cusset, Bull. Mus. Natl. Hist. Nat., B, Adansonia Sér. 4, 10(2): 174. (1988)
    • Dalzellia auct. (non Wight), in Cusset & Cusset (1988) & Qiu and Philbrick (2003)
    • Tristicha auct. (non Thouars), in Cook & Rutishauser (2007)

Note: Genus and synonymy under review according to WCVP (2021) and there is yet little consensus across the sources below.
