Philodendron riparium
A little-documented philodendron endemic to Ecuador, rated Vulnerable by the IUCN because of habitat loss. As its name suggests, it lives beside water: herbarium labels describe it as a vining epiphyte on trees along lake and river margins in the Amazonian lowlands, sometimes also on the ground. For growers, that means constant warmth, very humid air, bright but broken light, and a climbing or mounted setup.
Where it grows wild
Collectors found it on trees at Laguna Grande in the Cuyabeno reserve, where it grew on Macrolobium acaciifolium, a characteristic tree of seasonally flooded blackwater forest, in large groups on cushions of trapped debris. Another label records it on Pithecellobium longifolium, about 6 m back from a river's shoreline, in partial shade and moist conditions, as a vining epiphyte that was also seen growing terrestrially. A third comes from beside a small, boulder-strewn creek. Wikipedia describes its habitat as moist lowland and montane tropical forest.
The four wild records with an elevation span 185–265 m (median 265 m), all in the lowlands. Wikipedia's mention of montane forest is not supported by any dated record seen here.
