Hoya klossii

Hoya klossii is a New Guinea montane species described by Spencer Moore in 1916 from Cecil Boden Kloss's collections on the 1912 to 1913 Wollaston expedition in western New Guinea. Herbarium records place it in mid-montane forest from the Vogelkop and Paniai lakes to the Mt Kaindi summit area at 2,360 m, so it is a cool-growing hoya that wants a real night drop and never bakes.

Where it grows wild

An epiphytic climber of mid-montane and mossy forest in New Guinea; a 1993 Mt Kaindi collection at 2,360 m is labelled mid-montane forest, and other records come from the Jimi Valley, the Nettoti Range and Lake Paniai, all upland.

Recorded at 2,360 m on Mt Kaindi, with other localities at roughly 1,500 to 2,000 m. Only two records are georeferenced, one of them a lowland-coded 1913 point at 444 m that probably marks the expedition base rather than the collection site.
