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 
19 14.' 1 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.
