Hoya oblongacutifolia

Hoya oblongacutifolia (Costantin, 1912) is a lowland hoya of the seasonally dry parts of Thailand, Cambodia and Vietnam, collected on coastal rocks and in deciduous scrub on Si Chang island and in shaded evergreen forest near Sikhio. It is a warm grower that takes a hot, dry, bright winter in stride and expects a monsoon summer.
