Philodendron fibraecataphyllum M.M. Mora & Croat, ined., in press,  is a not yet officially published, very attractive species with ribbed foliage which undergoes a substantial metamorphosis from its juvenile to mature form.
It is an hemiepiphytic appressed-climber. Petioles are cylindrical, firm, dark green, finely palelineate-striate to coarsely pale -warty throughout, matte; basal pulvinus prominent, light green to magenta. Leaf blades are hastate, long-acuminate to abruptlyacuminate at apex , with the basal lobes spreading outwards, subcoriaceous, darkgreen and semiglossy above, slightly palerand glossy below.
From the Modern Latin genus name Philodendron (Schott, 1830), from Greek philodendron, neuter of philodendros "loving trees," from philo- "loving" (see philo-) + dendron "tree" (from PIE *der-drew-, from root *deru- "to be firm, solid, steadfast," also forming words for "wood, tree"). The plant so called because it clings to trees.
