province of Benguet of middle northern Luzon the more 
genuine tree like species occur in the woodlands of the 
lower altitudes, and the shrubby ones usually inhabit 
the higher region of the limestone formation. None of the 
species are found on the extreme summits of the highest 
mountains. 
Dr. King, in his monograph of the Indo-Malayan and 
Chinese Species of Ficus, includes them under seven sections. 
Since all of these different groups are represented by our 
species, his sectional characters are here reproduced: 
Group I.—Pseudo-hermaphrodite; male flowers with 1 stamen 
and a rudimentary pistil. Peseudo-hermaphrodite flow- 
ers and gall flowers in one set of receptacles; fertile 
female flowers in another set. 
I. PALAEOMORPHE. 
Group II.—Unisexual or asexual; male flowers without rudi- 
mentary pistils. 
Section I.—Male, gall, and fertile female flowers on the same 
receptacle. 
Il. UROSTIGMA. 
Section II.— Flowers unisexual or neuter; male and gall flowers 
on one set of receptacles, fertile female and neuter 
flowers in another set. 
Ill. SYNOECIA. 
Section III.—Flowers unisexual; male and gall flowers in one set 
of receptacles, fertile female flowers only in another set. 
A.—Flower monandrous. 
a.—Receptacles chiefly axillary. 
IV. SYCIDIUM. 
b.—Receptacles mostly in fascicles from stem and branch- 
es. 
V. COVELLIA. 
B.—Flowers di rarely triandrous.
