Hoya lacunosa

A small-leaved, creeping epiphytic Hoya from the lowland and hill forests of Southeast Asia, from Myanmar and Thailand through Malaya, Sumatra, Java and Borneo to the Philippines. It grows in masses on the trunks and limbs of trees at forest edges, in open places and along rivers, so it gets more light and air than an understory plant.

Where it grows wild

A creeping and climbing epiphyte, sometimes on rocks, that roots along its stems and covers trunks and branches of host trees. It favours forest edges, open places and riverside trees in lowland and hill rainforest rather than deep forest interior.

The seven wild records with an elevation lie at 21–250 m (median 186 m). General sources give lowland to about 1000 m, so hill-forest populations probably exist that the few elevation records miss.
