Distribution  Malaysia Sabah - Mt Kinabalu only

Habitat 2,700-4,000 m

RHS Hardiness Rating H2

Conservation status Vulnerable (VU)

This, the most alpine species on Kinabalu is a real plantsman’s challenge, various introductions have grown and flowered in cultivation but it seems prone to soil borne diseases and does not persist well. It is well named with its narrow foliage looking very ericoid. The consistently long calyx lobes will distinguish it from other species which may approach it in general appearance.
