Hoya longifolia

A Himalayan hoya with long, narrow, thick leaves, ranging from Nepal and Assam through Myanmar and Yunnan to northern Thailand. Its wild sites have a warm, very wet monsoon summer and a cool, nearly dry winter, so it is one of the cooler-growing hoyas and benefits from a drier, cooler rest.

Where it grows wild

An epiphytic climber or trailer on trees in monsoon hill forest. Specific habitat notes for this species were not available to us; this is inferred from the measured sites and from other Himalayan hoyas.

The five measured sites lie at about 1500–2900 m, but most literature places Himalayan hoyas lower; the upper figure is probably at the edge of its range.
