Philodendron Superbum (SUPERB-um) is a scientifically undescribed Philodendron.  Brazilian botanical authority Dr. Eduardo Gonçalves (gon-ZAL-vas) of the Universidade Catolica de Brasilia is working on the specimen but to date no technical information is available other than Philodendron Superbum is an epiphytic climber that is variable in appearance.  An epiphyte (ep-a-FIT) is a plant that grows upon another plant.  The adaxial (upper) leaf blade surface is glossy and the underside is matte.

All Philodendron including Philodendron Superbum are aroids. An aroid is a plant that reproduces by producing an inflorescence known to science as a spathe and spadix. Most people believe the spathe is a "flower", it is not. The spathe is simply a specially modified leaf whose purpose is to protect the spadix at the center. On the spadix there can be found very tiny flowers when the plant is at anthesis. When ready to reproduce, the spadix produces male, female and sterile flowers which if pollinated by an appropriate insect, normally a beetle, will produce berries containing seeds 

Philodendron species are known to be highly variable and not every leaf of every specimen will always appear the same.  As can be seen in the photos on this page, Philodendron species go through morphogenesis (ontogeny) as they mature.  This link explains in non-technical language natural variation and morphogenesis within aroid and other species.
