Described to science in 1913, Philodendron callosum is found in Venezuela, the Guiana Shield, and northwestern Brazil, P. callosum is largely found as an epiphytic species growing on dead trees. epiphytes (ep-a-FIT) are those plant species that grow attached to another plant, in most cases a tree. But the epiphytic Philodendron callosum is botanically in a section of species that commonly grow on the ground and even on stone.  That Philodendron section is Philiopsammos.

 Almost all specimens in this section are limited to the Guiana Shield and the Amazon region near that part of northeastern South America. Rather than growing as epiphytes, species in sect. Philiopsammos are largely terrestrial or epipetric.  Epipetric species are those that grow on stone.  Section Philiopsammos includes approximately one dozen species, almost all are known to creep across the ground.   One common factor to species within this section is these Philodendron possess short internodes.   An internode is defined as the portion of stem between the plant's nodes.  The nodes are the places along a stem where leaves are placed.  Although Philodendron callosum is placed botanically in this section it tends to grow in the rain forest on dead trees as an epiphyte.  Philodendron species, and especially hybrid forms, are known to be highly variable and not every leaf of every specimen will always appear the same.  This link explains in greater detail the scientific principle of natural variation and morphogenesis.
