279 LEAFLETS or PHILIPPINE BOTANY [Vor. I. ART. 16 
about 10 em. across, glabrous except the puberulent younger 
portions, didymously rebranched, the branches subtended by 
vestiges of bracts; the 5 mm. thick heads densely fruited, 
, upon short peduncles; calyx cup elliptic, about 2 mm. long 
and 1.5 mm. in diameter, glabrous, thick, truncate, pur- 
plish; seeds solitary, 2 mm. long, hard, smooth, straw color, 
oblong but the upper portion much flattened and gradually 
tapering to the short curved brown tip. 
Type specimen 8973, A. D. E. Elmer, Baguio, Province 
of Benguet, Luzon, March, 1907. It climbs tall trees along 
streamlets between Amukao and Bayabos near Sablan, and 
its slender roots are used by the Igorrotes in making deer 
traps in the form of latches or loops. This species which 
the natives call Anafol is not at all common. Named in 
honor of Dr. Otto Warburg who described two other Philip- 
pine species, 
Artocarpus leytensis n. sp.—A stocky erect tree, 10 m. 
high or higher, with a bole 3 dm. in diameter; branches 
widely spreading, forming an umbrella shaped crown, the 
ultimate twigs rather thin, smooth and grayish brown. 
Leaves few at the ends of the twigs only, flat, spreading, 
subcoriaceous, glabrous above except along the  midnerve, 
shining green, much lighter green beneath and short pu- 
bescent, oblong, the lower one half occasionally inequilateral 
and usually narrowed írom above the middle, apex obtuse 
or acute, the base rounded or only emarginate, the medium 
sized blades 15 cm. long by 6 cm. wide, the entire mar- 
gins subinvolute; petioles 1 cm. long, short rusty brown 
pubescent; nerves 5 to 7 on each side of the midrib, very 
prominent beneath, ascendingly curved, reticulations also 
conspicuous. Infrutescence in the leaf axils of the young 
twigs, subpendulous; peduncles 2 cm. long, fleshy, covered 
with a short dense umber colored pubescence, longitudinally 
ridged when dry, gradually thickened toward the apex 
usually solitary; fruits obovoid in general outline, but very 
irregular in shape, ours 2 cm. across, usually only 1 to 5 
sections developing into seeds which are partially imbedded 
upon the 8 mm. thick fleshy corrugated receptacle; each of 
these sections bearing from 1 to 5 cells enclosing solitary
