Philodendron lupinum

Philodendron lupinum is a species from Acre in western Brazil, known to collectors chiefly through specialist importers rather than mainstream trade. It carries a broad, unlobed cordate-to-sagittate leaf on a climbing stem. Juvenile leaves are smaller with a velvety, bronze-to-reddish satin sheen, maturing into larger, glossier leaves with pronounced corrugated venation, though the simple heart-shaped silhouette itself changes little. Less broadly documented than more established Philodendron species due to its recent and limited introduction to cultivation. Its variegated selection adds irregular cream sectoring over the same broad leaf shape.
