INCOMPLETE SPECIES. 



4. Z. sp. 



Leaves not seen. Spike stout, 30 cm long, 6 cm wide, cylindric, obtuse, 

 the peduncle 7 cm long, covered with lax sheaths. Bracts large, oblong, 

 narrowed a little at the base, the upper margin truncate, rounded, 

 involute, 4 cm long, 2 cm wide, finely ribbed, glabrous. Bracteole 

 tubular, spathaceous, the limb lanceolate, hairy, 4 cm long. Calyx thin,

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 (>255, 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. 



7. AMOMUM L. 



Rhizome usually long. Leafy stems tall. Leaves lanceolate, oblong, 

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

 the rhizome. Bracts lanceolate or ovate, containing one or more flowers 

 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. 

 Style shorter. Capsule globose or oblong, sometimes covered with short 

 processes. Seeds numerous.
