Philodendron magnum Croat, sp. nov. is a terrestrial to epiphytic species. Petioles are obtusely flattened adaxially, weakly and obtusely sulcate toward apex, closelytransversely ridged throughout, warty then finally scaly towards apex on juveniles, medium green or dark brown-green, matte or semiglossy, sometimes dark green adaxially, yellow-green abaxially,
reddish toward the base. Leaf blades are blade moderately coriaceous, broadly ovate, deeply cordate at the base, broadly triangular and ending in anacumen at the apex, dark green and weakly glossy above, much paler and semiglossy 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.
