Species novae Acoridii generis in Philippinis insulis indigenae. 81 
26 cm long, 15—18 mm wide, prominently 3-nerved, the lateral nerves 
giving the leaf the appearance of being marginate-winged. Lamina de- 
current on the petiole, which is 10 cm long. Peduncle shorter than the 
leaves and petioles, slender, flexuose, 20—30 cm long. Flowers reddish- 
brown when dry, in dense, spicate, cylindrical racemes. Racemes 7—8 cm 
long. Bracts 4—5 mm long, subacute, exceeding the ovary. Divisions 
of the perianth about equally long, obtuse or sub-acute, linear-oblong. 
Lip much broader than the sepals and petals, margin entire, 5—8 mm 
long, 2 mm wide; at base, on the lateral nerves two lamellae, 1 mm 
long. Apical wing of column quadrate, the summit irregularly and 
minutely crenulate, lateral wings from above the middle of the column-
