as the bracteoles, membranous, terminated by :> yellowish 

 oblong punctate lobes 4 mm in length; corolla red, the tube 

 as long as the calyx tube, glabrous a.s is also the calyx; 

 lip bent over the stamen, a trifle longer than the calyx seg- 

 ments, deeper red streaked, roundly toothed or subentire around 

 the apex, obovoidly oblong in outline, pulverulent on the 

 outer side; fertile filament few mm long, very thick and 

 glabrous; anther in the bud state 5 mm long, oblong, the 

 yellow cells longitudinally dehiscent, connective thick and 

 black when dry, truncate and minutely emarginate at the top; 

 style thread-like, bearing a small clavate stigma. 



Type specimen number 9282, A. D. E. Elmer, Lucban 

 (Mt. Hanahao), Province of Tayabas, Luzon, May, 15»<)7. 



It was found in woods at 2250 feet altitude upon gravelly 

 stream banks. 



My field label does not definitely state that the heads 

 were terminal but my recollection is that they were. The

 not even crested, much less with a long recurved beak. May 

 it not be an Adelmerin f 



Zingiber negrosense Elm. n. sp. 



Several stemmed clumps; stems 2 m long, green, gla- 

 brous, 1.5 cm thick. Leaflets numerous, alternate, coriace- 

 ous, glabrous, divaricately spreading, shining, deep green on 

 the upper surface, paler beneath, scattering every 5 to 8 

 cm or closer set toward the top, the basal ones reduced 

 to mere bracts, the side more or less descending, broadly 

 lanceolate, the slenderly acuminate apex recurved, sessile, 

 obtuse at the base, when dry conspicuously lighter brown 

 beneath, the normal blades 3 dm long, 4 to 5 em wide 

 at or a trifle below the middle, edges toward the base 

 involute, entirely glabrous; sheaths only partly encircling 

 the stems, much overlapping, glabrous, the brownish colored 

 margins glabrous; ligule short, broadly rounded, at the base 

 decurrent along the sheath, rigid, sparsely hairy on the 

 sides and becoming glabrate; midrib ridged beneath, grooved 

 abo?e, stout where the blade attaches to the sheath. In-
