somewhat larger and the apical ones smaller; bracteole 

 2.5 cm. long, hyaline and glabrous, enveloping the flower, 

 faintly veined, purplish spotted toward the obtuse apex, 

 8 mm. wide, broad at the base, oblong; calyx spatha- 

 ceous, 1.5 cm. long, likewise hyaline, parallel veined, 

 apex obtuse, entirely glabrous; corolla tube 3 cm. long, 

 gradually enlarged toward the top, otherwise very slender; 

 lateral 3 lobes 1.5 cm. long, very flaccid, purplish streaked 

 in the middle region, margins similarly spotted, the side 

 ones narrower and acuminately pointed, broadly lanceo- 

 late especially the middle one; lip 2 cm. long, 1.5 cm. 

 wide, cuneate at the base; the lamina with a pair of 

 lobules from the base, broadly oblong, the main or middle 

 portion terminated by a subtruncate usually notched apex, 

 all purplish spotted and streaked, the thin margins crisp; 

 free filament very flat, purple spotted, glabrous, short; 

 anther at least 1 cm. long, linear or a trifle wider to- 

 ward the bifid base, entirely glabrous, the connective 

 extended into a slender recurved spotted beak; style 

 thicker toward the distal end and similarly spotted, termi- 

 nated by a ciliated infundibular stigma protruding from 

 the end of the anther beak; ovary glabrous, bearing a 

 pair of yellow erect glabrous very linear appendages 

 4 mm. in length. 



Type specimen number 14317. A. D. E. Elmer, Irosin 

 (Mt. Bulusan), Province of Sorsogon, Luzon, October, 1915. 



Dense patches in stony ground of open meadows at 

 500 feet altitude. The flowering heads were wholly green, 

 turing red in the fruiting state. "Layag sa solog" in 

 Bicol. 



Possibly only a rank form of Zingiber zerumbet (Linn.) 

 Sin,, but our plant is much larger, the stipules or ligules 

 being twice the length, and the leaves two to three 

 times as long. 



Zingiber bulusanense Elm. n. sp. 



Few stemmed clusters. Stems stout, 2 m. long or 

 longer, ascending from the base, reclining toward the 

 top, 2.25 cm. thick, dark green, enlarged at the base, 

 the basal one third leafless. Rhizome short, crooked, 

 few and short branched, appearing as a nodulose clus- 

 ter; roots long, fibrous, yellowish as the rhizome, arising 

 from both the stem bases and the roots tocks. Larger 

 leaves divaricate, alternate, 3 to 6 cm. apart, reduced 

 and scattered toward the base, more numerous and nar 

 rower toward the distal end, the slenderly acuminate 

 point recurved, coriaceous, paler green beneath, curing
