 circiter 1.8 cm longis, extus adpresse pubescentibus ; filamentis 

 numerosis, 8 ad 10 mm longis, glabris, deorsum (2 mm) connatis ;

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 

 2 mm 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. Sd.

 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 camelUaeflora Kurz, but is very different in 

 its floral characters.
