slightly larger. Lateral sepals narrowly ovate, about 6.7 
mm. long and 8 mm. wide, short-acuminate, concave, 
1-nerved or very indistinctly 3-nerved, carinate near the 
apex with the keel extended into a short apicule. Petals 
much larger than the sepals, elliptic-ovate, about 10 mm. 
long and 7 mm. wide, acute, 9-nerved shortly above the 
minutely papillose base, minutely ciliolate, without re- 
ticulated veins. Lip very broadly rhombic-ovate, 14- 
nerved without reticulations, rounded or subacute at the 
apex, about 7.2 mm. long and 9.8 mm. wide near the 
base, minutely ciliolate, very minutely papillose at base. 
Column short, velutinous, extended in front into a fleshy 
compressed-ovate velutinous callus which is long-setose 
on each side at the base. Pollinia four, complanate-py- 
riform, in two unequal pairs. 
Telipogon parvulus is remarkable for its small size 
throughout. It differs from 7°. gracilipes Schltr. in its 
much lower stature, smaller leaves and dissimilar fewer- 
nerved lip which is decidedly broader than long.
