Hab. Perak: Kinta! 
This is sometimes called by the Malays “ Angrek Bunga 
Kasturi,” ¢.e., mnusk-flower orchid, from the strong musky smell 
emitted by the upper sepal. 
Neither in this nor any other species of the genus have I ever 
found the labellum “ mobile ” or “ elastic,” at least not more so 
than in Vanda or Stauropsis.

This fine species is well known to the residents of Singapore 
as the spider orchid, and has long been in cultivation there. 
There is a mass of it in one of the trees in the Singapore 
Botanic Gardens, measuring about 8 feet through. 
Tt flowers several times in the year. The flowers are rather 
smaller than those of R. Arachnites, Lindl., and quite scentless. 
The petals and sepals are white, more or less thickly barred 
with dark pink. The lip is also thickly striped with crimson, 
often nearly entirely self-coloured except for a buff stain in the 
centre and a buff spot on each side lobe. The anther is conical, 
blunt, not much taller than the margin of the clinandrium, with 
an obtuse beak. The pollinia are elliptical ; the pedicel dilated 
upwards from a broad base, the disc is broad and oblong. The 
stigma has a tooth rising from the lower margin which nearly 
divides it in two.
