latter verticillate, 1 to 2 cm. long, the bracts persistent, ovate, lanceolate,

 mm. long, truncate. Petals 4, pink, inequilaterally broadly obovate, obtuse, 

 6 to 7 mm. long, 5 to 6 mm. wide. Stamens 8, the filaments 3 mm., the

Type specimen No. 5805 (A. D. E. Elmer), Mount Santo Tomas, Provinca 

 of Benguet, Luzon, March, 1904; also No. 937 (Forestry Bureau), collected 

 by Barnes, same locality, May, 1904. 



The structure of the hairs in this species is very peculiar; none of them 

 exceed 1 mm. in length, being thickened and subplumose.

CLETHBACEJE. 



Clethra luzonica, sp. nov. 



A shrub with elliptical ovate or somewhat obovate acute subcoriaceous 

 leaves, the young branches, under surface of the leaves, panicles, and calyx 

 densely ferruginous stellate pubescent. Branches grayish brown, striate, 

 glabrous except the ultimate branchlets. Leaves 2.5 to 6 cm. long, 1.5 

 to 3 cm. wide, the base rounded, the margins above slightly serrate, the 

 upper surface with scattered stellate hairs, sometimes nearly glabrous; 

 nerves 10 to 12 on each side of the midrib, prominent beneath and especially 

 densely stellate pubescent; petioles stout 5 mm. long. Infloresence a 

 terminal panicle, 6 to 8 cm. long, the branches racemose, spreading, the 

 low r er ones 5 to 6 cm. long. Calyx, in fruit, 3 mm. long, the lobes lance- 

 olate or ovate, acute. Petals slightly united at the base, 3.5 mm. long, 

 1.8 mm. wide, obtuse, glabrous. Stamens 10, not exserted, the filaments 

 flattened at the base, 2.8 mm. long, the anthers 0.5 mm. long. Capsule 

 globose, densely pubescent, 3 mm. in diameter, the persistent style glabrous, 

 2 mm. long. 



Type specimen No. 5810 (A. D. E. Elmer), Mount Santo Tomas, Province 

 of Benguet, Luzon, March, 1904. A small stunted shrub growing on the 

 exposed summit of the mountain at an altitude of about 2,500 m. above 

 the sea; in fruit, March, 1904, but with few subpersistent corollas. A 

 species apparently most closely related to Clethra lancifolia Turcz., but 

 differing from that species in its smaller, differently shaped leaves, and 

 its peculiar stellate pubescence.
