A small epiphytic acaulescent herb. Roots flattened, 
strongly 1-nerved, 2-8 mm. broad, mostly less than 10 
em. long. Peduncle filiform, papilliferous, fractiflex, 
commonly less than 7 mm. long. Bracts of the inflores- 
cence lanceolate, usually about 2 mm. apart, about 1 mm. 
long. Perianth parts ocellate with crystalline inclusions, 
more or less fleshy, the sepals and petals adnate at the 
base for a short distance. Dorsal sepal linear-lanceolate, 
acute, 1-nerved, about 3 mm. long and 0.75 mm. broad. 
Lateral sepals lanceolate, acute or obtuse, 3-3.5 mm. long 
and 0.75—-1 mm. broad. Petals lanceolate,acute, l-nerved, 
about 2.5 mm. long and 1 mm. broad. Lip 3-lobed, broad-

callus near the apex ; lateral lobes inconspicuous, rounded, 
not separated from the mid-lobe by a sinus; at the base

with a pair of oblong-ovate stelidia; rostellum bifid. 
Taeniophyllum saccatum is most easily distinguished 
from all of the other known Philippine species by the 
much enlarged saccate portion of the spur. The species 
most closely allied to it seems to be 7‘ H/meri, which is
