Hoya obcordata

Hoya obcordata (Hooker, 1883) is a little-known Himalayan hoya from Sikkim and the Darjeeling hills, with old collections from Yuksom and Chakoong and one modern observation from Bhutan. Nothing is published on its cultivation; treat it as a cool, seasonal grower like other eastern Himalayan hoyas, with warm wet summers and a cool dry winter.

Where it grows wild

Presumably an epiphyte in warm-temperate broadleaf forest of the Sikkim Himalaya; the collection places (Yuksom, Chakoong in the Teesta valley) sit around 1,500 to 2,000 m. No habitat notes are attached to the records.

Probably 1,000 to 2,000 m, from the collection localities; no record carries an elevation.
