Distrib. Borneo (Kinabalu, 10,000-12,000’, Haviland). 
A creeping shrub, 10-15 em. high, with greenish flowers close to the 
ground, as they occur in the axils of the lowest leaves, the leaves being 
ageregated towards the ends of the branches. It is abundant wherever the 
vegetation opens out, both on the serpentine ridge, the dwarf sub-summit 
forest and granite core to the summit, where it forms one of the chief 
components of the vegetation. It also occurs on the serpentine of the 
Maraiparai spur. The margins of the leaves are serrate in my specimens, 
but are figured as entire in the plate quoted above.

This beautiful rhododendron is very conspicuous on the mountain. On the 
rocky shoulder above Lobang it was just coming into flower as a spreading 
shrub about 6-7 m. high and of typical rhododendron habit, and was very 
general as a small tree at Pakapaka by the Kadamaian torrent. The fino 
yellow flowers are of a wax-like consistency. It grows indifferently as an 
epiphyte or on the ground.
