Mindanao, Lake Lanao, Camp Keithley, Mrs. Clemens. 
A fine species, allied to Z. spectabile Griff. Unfortunately no leaves were 
collected, nor was any description given of the habit or color, and I had only one 
poorly preserved flower to examine. The specimen is therefore insufficient for 
a proper description. 
5. Z. sp. 
Stem 2.4 m tall. Leaves lanceolate, petioled, the base narrowed grad- 
ually to the petiole, apex acute, 38 cm long, 7 cm wide, the petiole 2 cm 
long, glabrous; ligule large, 1 cm long, rounded. Spike subterminal on 
the leafy stem, deflexed, cylindric, 8 cm long, 3 cm thick. Bracts obovate, 
rounded, • white, 1 cm wide, glabrous except for a few hairs on the 
edges, strongly ribbed. 
Luzon, Province of Benguet, Sablan, Elmer 6255, very rare, on precipitous 
slopes in deeply shaded ravines. 
There are no flowers on the specimen, which is therefore unidentifiable, but 
it is very distinct from any other Philippine species.

or linear. Inflorescence obconic, or elongate, on a short peduncle from

inclosed in thin bracteoles. Calyx as long as the corolla-tube. Corolla- 
lobes oblong or lanceolate. Staminodes absent or small. Lip large often 
convolute. Stamen broad, crest rounded, entire, or usually 3-lobed.
