chartaceous, 6 to 11 cm long, 1.5 to 3.5 cm wide, subequally 

 narrowed upward to the acutely acuminate apex and below to 

 the acute base, the margins subentire to irregularly serrulate, 

 the upper surface brownish-olivaceous, glabrous or with scat- 

 tered stellate hairs along the midrib and nerves when young, 

 the lower surface paler, sparingly stellate-pubescent; lateral 

 nerves 10 to 12 on each side of the midrib, distinct; petioles 

 pubescent, 1 cm long or less. Panicles ferruginous- to subcine- 

 reous-pubescent, the indumentum dense, short, stellate, the 

 branches often slender, 10 to 20 cm in length, the buds on young 

 branches crowded and subtended by the conspicuous bracts, in 

 anthesis somewhat scattered, their pedicels up to 3 mm in length 

 and persistent after the flower falls, the bracts deciduous, linear- 

 lanceolate, densely pubescent, 5 to 7 mm long. Flowers white 

 or greenish-white, numerous. Sepals ovate to oblong-ovate, 2 

 to 2.5 mm long, somewhat acuminate, densely pubescent. Petals 

 obovate, glabrous, 3 mm long. Ovary pubescent; style 2 mm 

 long. Fruit depressed-globose, 2.5 to 3 mm in diameter.

It is suspected that this is the form reported from Borneo by Stapf 

 and by Miss Gibbs as Clethra canescens Reinw., but it is remarkably 

 distinct from Reinwardt's species as I understand it, and as interpreted 

 by J. J. Smith from Javan and Celebes material; Reinwardt's type was 

 from Celebes, and no satisfactory description of it was published until 

 1914. 4 Koorders 19280 from Celebes unquestionably represents Reinwardt's 

 species, and represents a species from which I am now of the opinion that 

 Clethra williamsii C. B. Rob. of Mindanao cannot be distinguished. It has 

 coriaceous leaves, with from 17 to 20 pairs of lateral nerves, while the 

 form above described has at most chartaceous leaves with but 10 to 12 

 pairs of lateral nerves. Clethra dementis Merr. is distinctly more closely 

 allied to the Philippine C. lancifolia Turcz., than to C. canescens Reinw.
