Monstera deliciosa var. sierrana is an incredible ecotype of M. deliciosa found in the Sierra Juarez mountain range in Oaxaca, Mexico. This particular form was first collected in 1961, with 7 pressings existing in herbaria from original collection. Foliage can be distinguished from classic deliciosa by a repressed or flat sinus, deep-cut pinnatisect fenestrations to the midrib, and a cluster of secondary fenestrations. There two persistent clones of sierrana in cultivation; the Sierra Juarez ecotype and the Hawaiian clone. The material I possess and matured out is the Sierra Juarez ecotype. Here are some progression pics of this stunning plant maturing.
