disposed along the margin of the galea but not adherent to it, 

 half-exserted and meeting at the summit ; lip linear obtuse 

 decurved, widened above the middle, thick and fleshy, trans- 

 versely wrinkled near the base, about 8 mill, long ; rostellum 

 ascending, the arms divaricate ; anther horizontal ; ovary cylin- 

 drical, transversely wrinkled. 



Described from several living specimens. Colour of the sepals 

 dingy white with pale greenish-yellow patches, tipped with pink ; 

 petals and lip pale greenish-yellow ; rostellum white ; anther 

 yellow; leaves and bracts green with rusty red tips, the two 

 lower leaves maroon on the under surface. A very distinct 

 species, apparently allied to D. extinctoria, Reichenhach fil., 

 resembling it in the shape and setting of the galea, but much 

 more robust, leaves and flowers larger, and diflerent in appear- 

 ance. Sender placed it in the section Coryphsea, but in that 

 view I cannot concur. I have only seen it once, viz., on the 

 station last above mentioned, on Oct. 2, 1889, where there were 

 about 50 plants, but most of them past the flowering period.
