Hoya aurantiaca

Hoya aurantiaca is a Philippine wax plant described in 2009 by Kloppenburg, Siar and Cajano, named for its orange flowers. Almost nothing has been published beyond the description, so this profile treats it as a typical warm, lowland Philippine epiphytic hoya and should be adjusted if a cooler origin comes to light.
