摘要

Calathea monstera H. Kenn. from Panama and western Colombia is described as new. Calathea monstera belongs to the “Omata group” of Calathea. It shares a similar inflorescence and capsule morphology with C. sanderiana (Sander) Gentil, but is distinguished by the longer and narrower leaves, the acute to acuminate vs. obtuse apex, the markedly unequal' vs. equal-sided leaf base and the non-pattemed juvenile foliage.
