Hoya pachyclada
An epiphytic Hoya from mainland Southeast Asia, first described in 1939 and named for its thick, fleshy stems. It grows in seasonally dry tropical forest and in evergreen forest across Thailand, Laos, Cambodia and Vietnam, where a hot, rainy summer follows a clearly dry, cooler winter. Growers do best with bright light, a very airy mix, generous water in summer and a drier, cooler winter.
Where it grows wild
Wikipedia describes it as an epiphyte of seasonally dry tropical forest. A 1956 specimen from southeast Chanthaburi in Thailand, at 400 m, notes 'common on plain in evergreen forest' and 'climber; flowers yellow, smelling'. It climbs and scrambles over trees, and its thick stems and foliage suit a site that dries out seasonally.
Too few records to define a range. The herbarium specimen is from 400 m, and the measured sites are at 172 m (western Thailand) and 1335 m (Da Lat, Vietnam). The Da Lat record is from within the city and may be a cultivated plant.
