Hoya amicabilis

A recently described Javan Hoya, first recognised from photographs posted on Facebook and published in 2019. It is unusual for the genus in being a shrub rather than a climber, with thin, leathery leaves and bright yellow, bell-shaped flowers. It is known from a single locality in Purworejo, Central Java, so almost all growing advice has to be inferred.

Where it grows wild

The type plant was reportedly collected from a hollow tree trunk in a Pinus merkusii forest, so it grows as an epiphyte or in the rotting wood of trunks under a fairly open pine canopy. Nothing more is published about its microhabitat.

Recorded at about 900–1,000 m.
