calyx. 
A plant distributed under the name O. erubescens, Wall. by 
King collected at Gopeng by Kunstler No. 5853 of his herbarium 
and quoted by King as that species in the Materials, has velvety 
leaves hairy on the edge, and cannot be classed with O. erubescens, 
nor does it resemble any other plant I have seen.

Pahang: Telom (15644), Gunong Berembun at 6300 feet; 
Selangor: Bukit Hitam (Kelsall 1908) and near the Semangkok 
Pass (8584 Ridley). | 
Distinct in its widely dilated ribbed calyx, I took this at first 
for a form of O. erubescens.but it is very distinct, I find. A plant 
in young flower I got on Gunong Angsi in Negri Sembilan differs
