APOSTASIACEA OF THE MALAY PENINSULA. 411 
This species is near H. salaccensis, Blume, of Java, but is 
very distinct in the dense thick raceme of pale whitish flowers. 
The dorsal sepal is much narrower, of a glaucous greyish green, 
minutely punctate. It has a slender hair-like awn at the apex. 
The lateral sepals are white with three green veins, the 
awn much longer. The petals much resemble those of H. 
salaccensis, but the lip is longer in proportion to the sepals; 
the lobes very narrow, of a dull glaucous olive-green. The 
spur is long and straight. The stigmatic lobes are much 
shorter than in the other species, and the anther processes 
much longer. The pollen granules are very fine, the pedicel 
of a clear translucent golden colour, very slender. 
Though by no means a showy plant, this has a pleasing 
appearance; the peculiar greyish-green colour mixed with the 
white of the sepals being rather striking.
