pure delicate white ; they appear upon the leafless extremities 

 of the shoots in racemes of four or six flowers. The shoots 

 branch much, and form a compact bushy plant, their lower 

 ends having a tendency to become fusiform and bulbous. 



Cultivated readily by being attached to a stump of decaying 

 wood, on which it grows freely. It is among the most easy of 

 all the tribes of Orchideous plants for artificial cultivation. 

 Propagated by division of the branches. 



Both the above named varieties appear to be compre- 

 hended by Dr. Blume in his definition of Onychium cru- 

 menatum. A lilac variety is also noticed by the same 

 indefatigable Botanist.

O. bulbis subcylindricis monophyllis, foliis lanceolatis nervosis, panicula sim- 

 plici multiflora subsecunda, sepalis 4 fasciatis : inferiore minore bidentato, labelJo 

 pandurato, columnae alis linearibus obtusis, stigmate rostelloque pubescentibus.

Received from Rio Janeiro in 1825, having been sent by Mr. 

 David Douglas. This species has a contracted dwarf habit, 

 and is remarkable for the yellow olive-green colour of the 

 flowers, which appear in the stove in March. The leaves 

 grow singly upon round, elongated, smoothish, deep green 

 bulbs, and are peculiarly characterized by an appearance of 

 plaiting, which is very unusual in the genus. The margin of 

 the stigma and the anterior part of the clinandrium are also 

 singularly pubescent. 



A detailed description with a coloured figure of this has 

 been published in the Botanical Register, tab. 1007. It is cul- 

 tivated with some difficulty in decayed wood, or leaf mould.
