They pound up the flowers with water, and rub the paste over 
the body in cases of fever; and also use the leaves mashed 
with oil to thicken and strengthen the hair. The whitish latex 
of the plant has a very irritating action on the skin. 
I met with a plant in Pahang with larger and blunter leaves, 
which was out of flower, and may be a distinct species. . 
I believe that Griffith’s description of a Vanilla (Notule, ul. 
247), and the figure (Ic. Pl. As., t. 281), is intended for this 
species, and consequently Reichenbach’s V. Grifithit, 1.c., is the 
oldest name. There are, however, some slight differences 
between the Singapore plants and Griffith’s figure and descrip- 
tion, and no locality is given for the latter.

It is really difficult to separate the species of this genus 
satisfactorily ; and I think it highly probable that a good suite 
of specimens will show that all or nearly all the named species 
are merely forms of one. 
C. Thouarsii, Reichb. f., from Africa and its islands is, 
according to Blume’s figure (Orch. Archip. Ind., t. 44, fig. 1, 
A—C.), distinguishable by its narrower perianth segments ; and 
C. veratrifolia, Reichb. f., has shorter flowers than C. longiflora, 
Hook. f., in which, too, I find the sepals and petals are more 
spathulate and the latter more crisped along the edge. The 
height of the plant and form of leaf are characters too variable 
to be of any value; and Iam very doubtful as to the value of 
the length of the capsule, and proportionate size of the column. 
C. longiflora, Hook. f., is widely scattered over the peninsula, 
and sometimes may be found in abundance; but it seldom 
flowers. It is an inhabitant of damp dark jungle, sometimes 
growing on rocks. The flowers are pure white and deliciously 
scented. The natives call it “‘ Lulumbah Payah,” 1e., Marsh 
Curculigo.
