255 LEAFLETS OF PHILIPPINE BOTANY [Vor. I, Arr. 14 
nearly sessile probably fertile, smaller but with a similar 
perianth. 
Type specimen 7541, A. D. E. Elmer, Lucban, Prov- 
ince of Tayabas, Luzon, May, 1906; also 7632 from 
the same locality. The author collected it in the Prov- 
ince of Benguet, Luzon, three years ago and it has been 
confused with F. benguetense Merr., its nearest ally. In our 
region it is very common in the woods and in ravines 
skirting the base of Mount Banahao at 800 meters. 
28. F. tayabensis n. sp.—A tall and numerously branch- 
ed climber, 15 m. high; stems tough, about 5 cm. thick, 
round, conspicuously ringed or falsely jointed every 2 to 3 
dm. apart; wood porous, soft, reddish on the interior, covered 
with brown lenticelled bark; branchlets short brown pubes- 
cent when young, not rigid but comparatively short and 
crooked, forming tangled bushy masses near the top. Leaves 
alternate, widely scattered along the branchlets, flat or 
only slightly recurved at the apex, deep dull green above, 
much paler beneath, glabrous, quite unequal in size, ovately 
oblong to subelliptic, apex short acute, base rounded, char- 
taceous, margins entire or obscurely wavy toward the apex 
and subinvolute, the larger blades 13 cm. long and 7 em. 
wide at most, beneath finely tassellate; nerves very promi- 
nent beneath, 5 to 7 on each side, straight, much ascending, 
parallel, their distal ends curved and united, reticulations 
obscure; petiole stout, 1 to 2 cm. long, short rusty pubes- 
cent but soon becoming glabrous; bud scales 1 em. long, 
soft, light brown on the outside. 
Receptacles 1 to 3-clustered, in the leaf axils or in the 
axils of the fallen leaves, or occasionally clustered upon 
short suberect unbranched tubercles on the stem, subpen- 
dulous, ovoid or subglobose, dull red, the base abruptly 
contracted into a slender 3 mm. long stalk, umbilicus evenly 
rounded with the syconium; flowers apparently fertile female 
and neutra] only; the neutral flowers or possibly only the 
dwarfed fertile female in a circle beneath the umbilical 
scales, subsessile, arched; its segments dark brown, quite 
rigid, very unequal, glabrous, free, usually only 5, oblan- 
ceolate with ventrally folded sides and sharply inflexed tips; 
fertile female flowers upon 1.25 mm. long slender pedicels,
