which is also in cultivation, invariably grows in a wild 
state on a palm, Raphia madagascariensts. 
With regard to C. rhodochilum always growing on 
Platycerium, itself an epiphyte, it may be mentioned that . 
it is not at all unusual for one epiphyte to grow on 
another, but it is rare for the associated plants to be con- 
stantly the same. The same phenomenon is, however, not 
unknown among truce parasites. For example, so far as is 
known, all the species of Phacellaria, a small genus of 
shrubby parasites belonging to the Santalaceex, are para- 
sitic on different species of the equally parasitic genus 
Loranthus. 
Descr.—A_ tall, epiphytic herb. Psendobulbs clustered, 
oblong-conical, three to five inches long, at length purple- 
black. Leaves about eight to ten on a pseudobulb, dis- 
tichous, strap-shaped, two to three feet long, acute, 
flexible, recurved, dark green. Scapes simple, solitary, 
from below the pseudobulbs, nearly as long as the leaves, 
many-flowered. Practs lanceolate, acute, deflexed, shorter 
than the pedicels. Pedicels with the ovary about three 
inches long. Flowers crimson and green, very striking, 
about four inches in their greatest diameter. Sepals 
oblong-lanceolate, pale green, reflexed, about two inches 
long. Petals similar to the sepals, erect, apiculate, be- 
sprinkled with dark green spots on a light green ground. 
Labellum three-lobed; lateral lobes, except the crimson 
margin, of the same colour as the petals, and about a 
quarter as long; intermediate lobe obecurdate, about two 
inches in diameter, crimson, with a central, longitudinal, 
yellow band, spotted with green.—W. B. H.
