30a. Petiolar node as seen from the front or rear with apical margin rounded, slightly flattened, or weakly emarginate in the middle, but in this case, the free corners are always broadly rounded: orchidicola
30b. Petiolar node as seen from the front or rear with apical margin distinctly concave, the 2 free corners forming angles or produced as teeth: 40
