AvcUusT 1, 1908.] New PaANDANACEAE From Mr. BANAHAO 80 
largest of pandans known to occur in the Philippines. In 
this region it is strictly confined to gulches and ravines, 
and ranges from 700 to 1200 meters in the forests. 
Pandanus utilissimus n. sp. Tree, 4 to 6 m. high, 
forming small groups in dry ground and dense forests in 
swampy places. Stems solitary, short branched toward the 
top, with only a few short and thick prop roots, erect, 15 
or more cm. in diameter; bark grayish, not smooth and 
shining, its rings obscure; spines short, blunt, conical; branch- 
es few, sometimes several, erect or ascending, short and 
thick, usually somewhat constricted at the place of attach- 
ment and slightly thickened immediately above this. Leaves 
shining green or semiglaucous beneath, densely clustered on 
the ends of the branches, the larger ones 5 m. long, 2 dm. 
wide; the central or younger ones erect or ascending, with 
only their tips descending, apex acuminate, sharply spines- 
cent along the edges, the keeled dorsal line antrorsely serrate 
below the apex, the lateral ventral lines similarly serrate 
towards the apex; old leaves densely clustered, usually 
drooping from the middle, thick and rigid at the base, with 
a 6 cm. deep ventral groove near the base, persistent, 
splitting and wearing to shreds from the apex, the bases 
ultimately reduced to narcescent sheaths giving the stem or 
branches a thickened shaggy appearance especially when 
inhabited by epiphytic herbs.  Peduncle single, 1 to 2 m. 
long, hanging, stout, triangular, more or less thickened at 
the distal end; syncarpium green and glaucous, solitary, 
pendulous, 6 dm. long, 2 dm. in diameter, round or some- 
what obscurely angular, ellipsoid, equally rounded at both 
ends, solid and about 25 or more kilograms in weight, having 
the appearance of a jack fruit, (Artocarpus integrifolius Linn.); 
receptacle triangular, scaly, 4 to 7.5 cm. across its thickest 
portion; drupes 4.5 to 7 em. long, slenderly tapering from 
the pointed base to the crown which is 1 cm. in diameter, 
its angles irregular and blunt, the sides semiviscid and deep 
red except towards the base which has a tinge of yellow; 
apical cones 1 cm. high, 5 to 7-sided, blunt, with faint con- 
centric rings, glaucous green until maturity when a slight tinge
