Diagnostic Description

Philodendron rubromaculatum is a member of subgenus Philodendron, section Macrobelium, subsection Glossophyllum, series Glossophyllum characterized by its appressed-climbing hemiepiphytic habit, deciduous cataphylls, and small elliptic blades that are pale yellow-green abaxially and dry reddish tan with red punctations (hence the epithet from the Latin ‘‘ruber’’ meaning red and ‘‘maculatus’’ meaning spotted). Also distinctive are its small, yellow-green inflorescences with yellow female flowers.
Philodendron rubromaculatum is somewhat similar to P. longipes Engler as they both have elliptic blades with obscure veins and small, slender, cylindrical inflorescences. However, P. longipes has much larger blades that are never punctate and dry light olive-green on both sides, cataphylls that persist at the bases, and inflorescences that are green on the spathe tube and yellow-green on the spathe blade, with green female flowers.


Tropical rain forest transition to Premontane (T-rf/P), growing in dense regrowth forest.


Philodendron rubromaculatum is endemic to Colombia and is known only from the type locality on the western slopes of the Cordillera Occidental, in the Bajo Calima region.


IUCN Red List category. Conservation for Philodendron rubromaculatum must be considered as Near Threatened (NT) according to IUCN Red List criteria (IUCN, 2001). There is no reason to assume that it is exceedingly rare because only a tiny fraction of the Bajo Calima region has been studied, but it has not been collected elsewhere from other sites in Colombia.
