THE ORCHID REVIENV, 17 
CYPRIPEDIUM MASTERSIANUM. 
THE subject of our fourth figure is a very rare species which was described 
by Reichenbach, in 1879, as a plant of Sundaic origin. Materials for 
description were supplied by Messrs. James Veitch and Sons, of Chelsea, 
who state that they received the plant from the Royal Gardens, Kew; 
and here the record seems to be lost, It is allied to C. Bullenianum, 
Rchb. f., the staminode especially being almost identical in shape and size, 
though in other respects they are quite distinct. The leaves of C. 
Mastersianum are very obscurely tessellated ; the dorsal sepal much broader

and more obtuse, and the petals more spreading and less narrowed at the 
base. C. Hookere is readily distinguished from both by its far larger 
staminode, and other characters. C. Mastersianum has a green dorsal 
sepal, obscurely veined at the base, and a broad yellowish white margin ; 
brownish red petals, which are spotted with black on the lower half of 
the superior margin; and a light brownish red lip, which is spotted with 
dull purple on the side lobes; and a light green staminode with darker 
centre, It is now known to be a native of Java, from whence Messrs. 
Hugh Low and Co., of Clapton, have imported it. Our figure is reproduced
