REMARKS

We favor the orthographic variant Gynochthodes over the original spelling Gynochtodes , as Blume himself made the correction in his Flora javae ( Blume 1828). Brummitt &Taylor (1990) consider that the spelling corrected by the original author should be followed. Tetralopha is long established synonym of Gynochthodes . The synonymy was already proposed by Razafimandimbison et al. (2009: 885) for Imantina , Pogonanthus , and Sphaerophora .
