LEAFLETS OF PHILIPPINE BOTANY [Vor. I, ART. 14 
23. F. angustissima Merr. in Govt. Lab. Publ. 29; 11, 
1905. 
Represented by 9357, A. D. E. Elmer, Lucban, Prov- 
ince of Tayabas, Luzon, May, 1907. A low laxly branched 
undershrub in the woods of a dry ridge on Mount Banahao 
at 800 meters. Only one sterile plant was observed. The 
type was collected at Bosoboso, Province of Rizal, Luzon. 
Last year the writer secured fine fruiting specimens at Los 
Bafios, Province of Laguna, Luzon, which were distributed 
under number 8179. More recently it was sent up from 
Camp Keithley, Lake Lanao, Mindanao. It has strong af- 
finities to the Philippine F. cumingii Miq. and to the Ce- 
lebes F. irregularis of the same author.

Specimen 9377, A. D. E. Elmer, Lucban, Province of 
Tayabas, Luzon, May, 1907. It was collected on gravelly 
banks of the Mahapon River near Sampaloc. There can be 
no question that our specimen is typical of number 1921 which 
Cuming collected in the Philippines and on which Miquel 
based his description. In King’s monograph of the Species 
of Ficus of the Indo-Malayan and Chinese Countries, it is 
reduced to F. quercifolia Roxb. Stil there is some doubt 
whether our erect shrubby Philippine form is really the same 
as that from the Malay Islands and which is described as 
a small ground creeper. In its typical form it occurs at sea 
level near the coast and whether the variable forms of the 
higher interior regions can be classed with it is doubtful.

Bot. Gard. Cale. 1; 78, 1887.— Erect, rather stiff shrub, 2 
to 3 m. high; wood finely grained, medium hard, with light

sides, duller beneath, exceedingly variable in size and shape, 
ovately oblong or obliquely rotund, inequilateral, base bro- 
adly rounded to subcordate and oblique, apex abruptly 
acute, subentire or the younger ones distantly serrate, fin- 
ely punctate beneath; nerves 3 to 5 on each side, ascendingly 
curved, very prominent beneath, cross bars and reticulations
