May 31, 1919] Zingiberaceae of the Soksogon Peninsula 2973 



paler green beneath, edges more or less wrinkled, aver- 

 aging 5 inches apart, in 2 alternating rows; cones te- 

 rete, erect upon 3 to 5 inches long ascendingly curved 

 and imbricately bracteate peduncle arising from the rhizome 

 in the proximity of the stem base, 3 to 5 inches long, 2 to 3 

 inches across the middle, barely above ground; peduncle 

 gradually thickened from the base toward the 4 inches 

 long cone; bracts of the cone pointed, rigid, yellowish 

 brown except the upper or exposed portion which is deep 

 red; inner fruiting bracts pale green, even the persistent 

 calyx, watery and partly decayed, giving off a slimy 

 juice from the apex of the cone; carpels white, 1 inch 

 long, angularly compressed, slightly hairy, narrowed 

 toward the base; seeds numerous, covered with a fleshy 

 white membrane. 



Represented by number 16924, Klmer, Irosin (Mt. 

 Bulusan), Province of Sorsogon, Luzon, August, 1916. 



Collected in loose humus covered ground among thickets 

 along the border of woods at 1000 feet altitude. 



Both the types of Homstedtia conoulta Ridl. and 

 Hornstedtia lophophora of the same author were collected 

 by the writer in the Cuernos mountains of southern 

 Negros, the former in flower the latter in fruit. They 

 are both rank large leafed plants, especially the latter, 

 readily distinguishable from each other by the under 

 glabrous leaf surface of Amomum conoidtum (Ridl.) Elm. 

 and by the soft or velvety nether leaf surface of Amomum 

 lophophora (Ridl.) Elm. n. comb. (Homstcdtia lophophora 

 Ridl. in Leaf. Philip. Bot. n, 607, 1909). 



Amomum bulusanense Elm. n. sp. 



Loose clumps. Stems several, ascending, terete, green, 

 much and abruptly enlarged at the base, tips much re- 

 curved or reclining, 1.75 to 2.5 m. long. 1.5 cm. thick. 

 Rhizome horizontal, subterete, hard, short, occasionally 

 branched, yellowish. Leaflets horizontal or descending, 

 bract like toward the base, chartaceous or nearly so, 

 paler green beneath, margins wavy, apex quite abruptly 

 acute to acuminate and recurved, obtuse to obtusely round- 

 ed at the unequally sided base, alternating every 7 

 cm., petioled. curing lighter brown beneath, the upper 

 side more often greenish, glabrous, the narrow edge 

 reddish brown and nearly hairless or ciliate toward the 

 apex, oblong, 7 cm. wide, 3 dm. long; midvein ridged 

 beneath, glabrous and smooth, lighter brown, grooved 

 on the upper surface; lateral nerves straight, ascending, 

 not visible on the upper side; petiole stout, 1.25 to 2 cm.
