Hoya pubicalyx

A vigorous climbing epiphyte endemic to Luzon in the Philippines, described by Merrill from plants growing on trees along streams in damp forest near Mauban, Quezon Province. The measured climate there is hot, humid and wet all year with no real dry season, so it grows continuously. It is one of the easiest hoyas indoors: bright filtered light, warmth, and a chunky mix that is watered as it approaches dry.

Where it grows wild

The type collection (Ramos & Edaño, 1913) was made on trees along streams in damp forests at Mauban on the east coast of Luzon. It is a scandent, glabrous climber with fleshy leaves 10–14 cm long and large, many-flowered umbels. Recent Philippine enumerations treat it as confined to Quezon Province.

Few records carry an elevation. The type locality is in lowland forest near the east coast of Luzon, and no montane records are known.
