zust 8, 1914] NEW ARALIACEAE FROM MINDANAO 2331 
of the average ones 3 dm long, straight and stout, subterete, 
caniculate along the upper side below the blade toward the 
base, at the base thickened and provided with entire ring-like stip- 
ules, constricted at the distal end, green and glabrous; lamina 
of the average ones 4 dm across, orbicular in outline, 5-lobed 
nearly to the middle, the basal pair of lobes much smaller, 
base broadly cordate, glabrous, apex of the lobes rounded 
but terminated into a very sharp narrow point, the margins 
irregularly serrately dentate; veins as many as there are lobes, 
darker brown in the dry state beneath, stoutly ridged along 
the upper side; nerves of the lobed portion only about 9, 
only one half as many in the smaller lobes, ascendingly 
curved, more conspicuous on the upper surpace than on the 
lower, reticulations large and faint, the nerves in the central 
portion of the whole lamina very fine and divaricate. In- 
florescent umbel erect, terminal, subtended by reduced leaves, 
5 em across; stalks with their subtending pulverulent bracts 
atropurpureus, all erect or ascending, crowded, glabrate and angu- 
larly flattened, 5 to 8 em long, branched at the middle; branches 
again rebranched at the middle or merely articulate, sub- . 
tended by conduplicate 1 cm long glabrate more or less 
oblong and acuminately pointed persistent bracts; pedicels 
stout, compressed, brown puberulent, solitary or in pairs 
or even iif threes, 1.5 cm long, subtended by reduced bracts; 
distal end of ultimate branch or receptacle portion 5 mm 
thick; flowers including the buds aurantiacus, several to many, 
subsessile or pedicellate, subtended by a lacerated vestige of 
involucre, even the individual flowers subtended by fimbriate | 
bracteoles which are usually ciliate along the margins; pe- 
dicels 1 mm long, glabrous, becoming easily detached, a trifle 
thicker toward the distal end; every even thicker though 
similar in shape, 1.5 mm long, terete; buds ellipsoid or 
obovoid, 2.5 mm long, nearly as wide, easily becoming detached; 
corolla aurantiacus, towards 3 mm long, valvate in the bud state, 
ultimately separating into 4 petals, each segment with a 
faint midrib, glabrous; stamens 4, alternating with the cor- 
olla segments; the dark brown and glabrous filaments nearly 
as long as the corolla; anther much lighter brown or yellowish, 
broadly oblong, almost as long as the filaments, apex blunt, 
lobed at the base, dorsifixed; ovary crown a blunt 4-lobed
