Rhizome stout; pseudobulbs -5 in. apart, fusiform. Leaves 2, 
elliptic, thickly coriaceous, acute, 2-5 to 5 in. long, 1*5 in. wide; 
petiole *5 in. long, stout. Raceme from top of pseudo bulb 5 to 10 in. 
long, compressed, stout, not or hardly flexuous above. Flowers 
2 in. wide, ovary and pedicel -25 in. long. Bracts -5 in. long. 
Sepals linear-oblong acute. Petals narrow linear. Lip side-lobes 
long, blunt, midlobe wider round much shorter with 2 short ridges. 
Column hood acute. Hab. Rare and little known. A very stiff¬ 
leaved plant with the biggest flowers in this section. Pahang, 
Gunong Tahan, at 7000 ft. altitude. Selangor, Gunong Mengkuang 
Lebah (Robinson). Perak (Scortechini). Kedah, Gunong Bintang 
(Kloss). 
I take the Pahang and Selangor plants quoted to be C. anceps, because 
the leaves are very stiff and short coriaceous and the scape rigid with big 
flowers. They were white with 2 strong ochre ridges.
