rotundatis, margine leviter undulatis, cartilagineis; paniculis 
axillaribus, 10 ad 20 cm longis; floribus 5-meris, calycis glabris, 
lobis late ovatis, obtusis vel minute apiculatis, haud ciliatis, haud 
lineatis, corollae lobis late elliptico-ovatis, rotundatis, 1.4 mm 
longis, usque ad 4 connatis, obscure lineatis; bracteolis ovatis, 
acuminatis, 0.8 mm longis. 
A scandent shrub, glabrous except the inflorescences, which are 
obscurely puberulent. Branches brown, 4 to 5 mm in diameter, 
lenticellate, the ultimate branchlets about 2 mm in diameter, 
terete. Leaves ovate, chartaceous, 9 to 13 cm long, 5 to 7 cm 
wide, the upper surface brownish olivaceous, shining, the lower 
surface brown, the apex acuminate and slightly apiculate, the 
base broadly rounded, margins shallowly undulate, the edge of 
the leaf distinctly cartilaginous; lateral nerves 8 or 9 on each 
side of the midrib, rather prominent on the lower surface, the 
reticulations distinct, the ultimate ones plainly visible to the 
naked eye. Panicles axillary, ample, rather many-flowered, 10 
to 20 cm long, the primary branches slender, usually spreading, 
up to 10 cm in length, the flowers racemosely disposed on the 
ultimate branches, white or nearly so. Flowers 5-merous, the 
bracts oblong-ovate, acute or acuminate, about 1 mm long, the 
bracteoles ovate, acuminate, 0.8 mm long, the pedicels 1 to 1.5 
mm in length. Calyx glabrous, about 1.5 mm in diameter, 
eglandular, the lobes broadly ovate, often minutely apiculate, not 
lineate and not at all ciliate, entire. Corolla lobes broadly ellip- 
tic-ovate, rounded, about 1.4 mm long, extending to or below the 
middle of the corolla, obscurely lineate. Stamens inserted near 
‘the base of the corolla lobes, their filaments slender, 0.6 mm 
long. 
Luzon, Tayabas Province, near Tagbilao, Bur. Sci. 26872 
Edafio, March, 1917. In thickets or forests, apparently from 
low altitudes. 
This species is probably most closely allied to Maesa coriacea 
Mez and among the Philippine species comes nearest to Maesa 
megaphylla Merr. from which it is distinguished, among other 
characters, by its undulate and distinctly reticulate leaves.
