margine crenato-serratis, dentibus glanduloso-apiculatis, nervis 
utrinque circiter 12, subtus valde perspicuis, arcuato-anastomo- 
santibus, reticulis laxis, perspicuis; floribus axillaribus, solitariis, 
sessilibus, circiter 3 cm diametro; sepalis suborbicularis cum 
bracteolis persistentibus, 6 ad 7 mm longis; petalis 5, obovatis, 
circiter 1.8 cm longis, extus adpresse pubescentibus; filamentis 
numerosis, 8 ad 10 mm longis, glabris, deorsum (2 mm) connatis; 
fructibus ovoideis, 1.5 ad 2 cm longis, 2- vel 3-locellatis. 
A shrub about 3 m high, the younger parts more or less 
appressed-pubescent, the older parts glabrous, branches terete, 
grayish or brownish, the young branchlets greenish when dry. 
Leaves chartaceous to subcoriaceous, oblong-obovate, suboliva- 
ceous or greenish when dry, somewhat shining, glabrous on 
both surfaces or when young very slightly hirsute on the lower 
surface, 8 to 15 cm long, 2.5 to 5.5 cm wide, obtusely acuminate, 
the base cuneate, the margins crenate-serrate, the teeth glandu- 
lar, apiculate; lateral nerves about 12 on each side of the midrib, 
very prominent on the lower surface as are the lax reticulations; 
petioles 5 to 8 mm long. Flowers axillary, solitary, sessile, 
about 3 cm in diameter. Sepals subcoriaceous, persistent, 
broadly ovate to reniform-ovate or orbicular, rounded, 6 to 7 
mm long, externally densely appressed-pubescent, the subtend- 
ing bracts numerous, imbricate, similar to the sepals but smaller. 
Petals 5, obovate, about 18 mm long, rounded, externally ap- 
pressed-pubescent. Stamens indefinite, the filaments 8 to 10 mm 
long, glabrous, united for the lower 2 mm, the anthers broadly 
ovoid, about 1.2 mm long. Ovary ovoid, pubescent, 2 to 2.5 
mm long; styles 5 to 6 mm long, glabrous, the 5 arms about 
2mm in length. Fruits ovoid, brown, ultimately glabrous, 1.5 
to 2 cm long, usually 2- or 3-celled and with a single seed in 
each cell, the seeds smooth, slightly compressed, narrowed at 
both ends, about 1.5 cm long.

March, 1916; Bukidnon Subprovince, Mount Candoon, Bur. Sci. 
38839 Ramos & Edafio, July, 1920. In damp forests at an al- 
titude of 1,200 meters. Originally determined as a Thea. 
This is the first representative of the genus to be found in 
the Philippines. In vegetative characters it rather closely re- 
sembles Pyrenaria camelliaeflora Kurz, but is very different in 
its floral characters.
