Notes
The basionym C. pleiogonus had been previously assigned to E. triglochidiatus. However, the original description mentions a plant with 13 ribs, 9 radial spines and 4 central spines, which does not agree with E. triglochidiatus. Blum & al. (2017) suggest that C. pleiogonus may belong to E. polycanthus.A
