Conservation Notes: This endemic Hoya is still rare in cultivation in Philippine gardens although it has been reported in nurseries abroad. The plant is threatened by overcollection in its native habitat in the forests in Surigao and by habitat destruction. The species was named after me by Dale Kloppenburg an avid Hoya enthusiast who has been studying and describing numerous Philippine Hoyas since the 1980s.
