May 31, 1919] Zingiberaceae of the Sobsogon Peninsula 



gradually thickened toward the apex; stigma infundibu- 

 lar, the margin with hyaline ciliate hairs; ovary glabrate, 

 with a pair of yellowish white linear appendages 4 mm. 

 in length. Unopened capsule 3 cm. long, fully one half 

 as wide, truncate at the apex, bluntly pointed at the ba.se. 

 triangular but the ventral side broader than the two 

 aorsal sides, white throughout, watering off at the apex 

 and dehiscing from the apex downwards along the 2 

 lateral sutures and along the dorsal loculicidal one; the 

 3 carpels are very unequal in width, the rear broad 

 one remains practically straight, while the 2 lateral equal 

 ones press outward and become widely separated nearly 

 to the base, the sides of the carpels become reflexed 

 rather prominently, gaining sufficient strength to crowd 

 the imbricate bracts far out in order that the seeds may pro- 

 perly escape; seeds in the lateral cells 7 to 10, attached 

 to the thick white placenta in 2 close rows and al- 

 ternating in an ascending fashion, the dorsal cell contains 

 only one or at most a few seeds at the top of the 

 cavity; seeds surrounded by a white fleshy membrane 

 and which becomes lacerated from the apex toward the 

 base, sessile or subsessile, seeds 6 mm. long, nearly one half 

 as thick, ellipsoid or more obovoidly so, shining, blackish 

 brown, purplish at the basal attachment of the hilum, 

 terete or very obscurely angular toward the apex. When 

 dry the seeds are disseminated by ants, when wet they 

 are washed out. 



Type specimen numbers 15178 and 16914, A. D. E. 

 wmer, Irosin (Mt. Bulusan), Province of Sorsogon, Lu- 

 zon, November 1915 and August 1916 respectively. 



Seen several times in the forests at 1500 feet alti- 

 tude of mount Bulusan, and is easily recognized from 

 all other Philippine species by its dirty pubescent sheaths.
