maculata, from which it may be distinguished by its rosy 

 lilac or mauve sepals and petals. Flowers two to three inches 

 across ; lip white, yeined and streaked with crimson, having 

 a yellow blotch in the throat. It is a beautiful species, and 

 lasts a long time if kept free from drip. A single pan of this 

 plant, grown by Mr. Fetch at Manley Hall, bore eighty 

 flowers in October 1872. 



P. maculata (Khasya Hills). — This has pale green inflated 

 bracts, by which it may be readily distinguished when 

 growing. Its sepals and petals are pure white ; lip white and

 white centre. It lasts a fortnight in beauty. Like all the 

 rest of its congeners it has pectinate ridges up the centre of 

 the disc.

 time ago, this beautiful little plant still continues rare. Its 

 pseudo-bulbs are from two to four inches high, tapering from 

 the base to the apex, where they bear three or four dark green
