Anthurium Decurrens

A botanically notable lowland Amazonian epiphyte described by Eduard Poeppig and placed by Croat, Lingán, and Hayworth (2005) into the newly erected section Decurrentia — a small, tightly defined group of closely related Amazonian species united by their short internodes, elongated epunctate leaf blades, and winged or ridged peduncles. Native to a range spanning southern Colombia through Ecuador and Peru's Amazon basin provinces to Brazil's Acre state, it grows in lowland wet tropical forest at modest elevations of roughly 225-440 meters, making it a warm-growing species by anthurium standards and distinct from the high-elevation cloud forest species that dominate the collector velvet anthurium market. The common name "Walking Anthurium" references the plant's characteristic epiphytic behavior — its aerial roots and short-internode climbing habit allow it to advance across the surfaces it colonizes in the way that defines many epiphytic aroids. The leaves are elongated, narrowly oblanceolate to somewhat obovate, tapering prominently toward the base in the decurrent fashion that gives the species its name — the leaf base running downward along the petiole and stem in a distinctive way that is the defining character of section Decurrentia. The blade surface is semi-glossy to glossy green with clear, parallel-patterned primary lateral venation and characteristically wavy leaf margins, giving the foliage a clean, architectural quality that stands apart from the velvety or corrugated textures of more widely collected anthurium species.

As a lowland Amazonian species, this anthurium prefers consistently warm temperatures in the 65-80°F range without the significant nighttime temperature drops that benefit many highland species. Provide medium to bright indirect light — the glossy leaf surface is more tolerant of reasonable light levels than velvet-surfaced species but benefits from protection against direct harsh sun. Keep the medium evenly moist with excellent drainage in a rich, well-draining mix; never allow waterlogging. Humidity of 60-80% supports the best growth. Feed monthly with a balanced diluted liquid fertilizer during active growth. Toxic to humans and pets if ingested.
