same plant was sent by T. Lobb! and announced by Messrs. Veitch 
as coming from Borneo. Since T. Lobb collected likewise to 
Burmah, a mistake may have happened. 
Pseudobulbs pyriform, tumid, articulate, with sheaths; the lower 
sheaths emaciate, shining in the flowering plant; the two or three 
standing uppermost have fleshy cuneate-ligulate blades, with an 
obtuse-angled middle rib on the outside. Adventitious roots only 
basilar, very slender, filiform. Racemose inflorescence usually 
lateral, but occurs also terminal, even in the actual presence of the 
leaves, though these appear oftener falling off before the expansion 
of the flowers. Raceme very dense-flowered and very short, nearly 
capitate. Bracts triangular, scariose, one-nerved, equal to the 
pedicelled ovaries. Chin acute-angled, very variable in its length, 
sometimes clavate at its apex, sometimes extinguisher-shaped. 
Upper sepal ligulate-acuminate, with a blunt keel above its midrib 
outside ; lateral sepals triangular-falcate, just as long, extended 
for the formation of the chin at their base. Tepals cuneate- 
spathulate, unequally acute or acuminate, longer than the sepals 
in the manner of some Ceratobia. Lip cuneate-triangular, three- 
lobed at its apex; lateral lobes obtuse-angled, rectangular ; anterior 
lobe triangular, acute or acuminate, longer than the lateral lobes, 
undulated; a linear callus with elevated borders runs from the 
base of the lip towards the base of the anterior lobe, where it 
occurs either abrupt with a transverse ridge, or tridentate, a 
small short keel running from the middle tooth to the inner sur- 
face, or retuse with a small apiculus. Colwmn clavate, being 
singularly variable in the borders of the androcliniwm, it being 
tridentate, with blunt crenulate lateral teeth, or tridentate with 
the central tooth having two small lateral teeth below its apex, or 
equally quinquedentate. Strgmatic hollow oblong, having a second 
excavation below. ‘There is an angle at each side at the very 
base just where the claw of the column descends for the formation 
of the chin. Anther obtuse-emarginate, sometimes with a small 
apiculus in the sinus. ‘The back of the chin is green. Sepals 
and tepals white. Lip olive, with purplish violet veins. The 
anterior border of the callus is violet-purple. The anther is 
amethyst-coloured, with very numerous very small white dots. The 
anterior border of the callus is violet-purple. The colwmn is 
whitish, with many small purplish violet dots on the inner side. 
The pollinia are strongly coherent. The plant has the habit of 
some Lrias.
