识别要点：This new species is similar to P. bulbocodioides and P. formosana but differs from them by having a lip with an erose apical margin and lateral lobes of the lip not enfolding the column. In addition, it can be distinguished from P. bulbocodioides by having two calluses and from P. formosana by having conical pseudobulbs and narrower sepals and petals.
