 in the apex of the scape, rather small ; prevailing- colour yel- 

 low. Petals very unequal; the upper three ovate, striped 

 with purple lines and ciliate margins, that of the apex larg- 

 er, and filiform, those three are only a little longer than the 

 column, the lower two falcate, five or six times longer than 

 the upper three, united at the base under the lip which they 

 completely embrace and hide, they are of an uniform yellow 

 colour, and on account of their great size, when compared 

 to the rest of the flower, give to the whole that colour. Lip 

 united to the base of the column by an incurved claw, some- 

 what conical, but much recurved, internally cellular. Co- 

 lumn short, interior margins winged. Pollen masses two, 

 globular, covered by a two-lobed deciduous lid.

Received into the Botanic garden, from Mr. Pierard ; who 

 found it growing on the trunk of Lagerstroemia regina in 

 the northren border of Arracan, and observes that it is found 

 in the woods always only on that tree.* It blossoms in 

 March, but produces no fruit. 



* It is also found to grow well on the mango tree in the Bota- 

 nic garden.
