widest portion conspicuously ruffled clear to the much 

 extended apex, glabrous on both sides; filament succulent, 

 strap-like, the distal portion slightly pubescent, little 

 longer than the corolla tube, parallel veined; anther 

 connective thick and hard, curved dorsally, glabrous, 

 truncate, broad and deeply notched at the apex, not 

 crested nor hairy; anther cells 7.5 mm. long, curved 

 ventrally, glabrous, parallel except at the more or less 

 divergent ends; style filamentous, glabrous, thickened 

 toward the stigma which is short obconic, somewhat 

 flattened and glabrous; ovary densely hairy with a pair 

 of glabrous erect 4 mm. long by 1 mm. wide compressed 

 appendages. Fruiting head subglobose, 8 cm. in diameter, 

 dirty yellowish bracteated about the base; carpels yel- 

 lowish red or subroseus, sessile, contiguous and forming 

 a solid mass, obconic in outline, the smooth sides irreg- 

 ular and ridged, sessile, 3 to 4 cm. long when dry, 

 2.5 cm. across the top or widest portion, tapering from 

 the small base, the top portion or side excrescently ridged 

 about the short blunt calyx point, tawny appressed 

 pubescent all over; seeds murinus, 3 mm. across, angu-

Type specimen number 16925, A. D. E. Elmer, Irosin 

 (Mt. Bulusan), Province of Sorsogon, Luzon, August, 

 1916. 



Collected in loose humus covered damp soil of thickets 

 along borders of woods at 1000 feet altitude. Rare! 



Related to Homstedtia pandanicarpa (Elm.) Elm., yet 

 distinguishable by either the fruits or flowers. Carpels 

 of Homstedtia sorsogonensis Elm. are very irregularly and 

 rugosely ridged, not forming a thick continuous rim about 

 the apex; and the floral bract is much broaded and glabrate. 



Homstedtia subviridis Elm. n. sp. 



Dense tussocks. Stems erect, at least 1.25 cm. thick, 

 terete, 1.75 to 2.75 m. high, much recurved toward the 

 tips, pale green, sublucid, bulbose at their bases. Leaflets 

 numerous, 3 to 5 cm. apart, in two alternating rows, 

 reduced and scattering toward the base, more numerous 

 and narrower toward the distal ends, ascending except 

 those at the top, flat, chartaceous, only a trifle paler 

 green beneath, curing subviridus on both sides, petioled, 

 glabrous, the narrow brown line along the edges dense- 

 ly ciliate, narrowly oblong, apex gradually acuminate, 

 base subinequilaterally obtuse, the larger ones 6 cm. 

 wide, 4 to 5 dm. long; midrib pale brown, smooth, glabrous, 

 prominently ridged beneath, deeply sunken above; petiole
