but the other specimens cited, including one from near the type 
of Agrostistachys pubescens Merr. has rather pubescent leaves, 
but the other specimens cited, including one from near the type 
locality, have glabrous or nearly glabrous leaves. 
MACARANGA Thouars 
MACARANGA OVATI FOLIA sp. nov. 
Arbor parva, inflorescentiis ramulisque exceptis glabra, ra- 
mis circiter 1 cm diametro; foliis ovatis, chartaceis, integris, 
usque ad 25 cm longis, acuminatis, basi late rotundatis et dis- 
tincte cordatis, subtus glandulosis, nervis utrinque ,10 ad 12, 
perspicuis, petiolo usque ad 16 cm longo; infructescentiis late- 
ralibus, paniculatis, solitariis, e axillis defoliatis, 6 ad 9 cm lon- 
gis, pubescens; coccis solitariis, globosis, laevis, glabris, circiter 
4 mm diametro. 
A small tree, glabrous except the tips of the branchlets and 
the inflorescences, branches brown when dry, terete, the ulti- 
mate ones up to 1 cm in diameter, marked with large scattered 
petiolar scars, the leaf axils and the very tips of the branchlets 
ferruginous-pubescent. Leaves ovate, chartaceous, 20 to 25 cm 
long, 16 to 18 cm wide, entire, apex distinctly acuminate, base 
broadly rounded and distinctly cordate, the upper surface 
greenish-olivaceous, shining, the lower somewhat paler, with 
numerous pale-yellowish glands; lateral nerves 10 to 12 on each 
side of the midrib, prominent, the basal pair with about 10 
secondary nerves on the lower side, the reticulations subparallel, 
distinct; petioles reddish brown, slender, up to 16 cm long. 
Infructescences paniculate, solitary, in the axils of fallen leaves, 
spreading, 6 to 9 cm long, ferruginous-pubescent, the branches 
few, the primary ones 4 cm long or less. Pedicels about 1.5 
cm long, the bracteoles pubescent, oblong-obovate, somewhat 
toothed, up to 3 mm long. Fruit consisting of a single, globose, 
smooth, ultimately glabrous coccus, about 4 mm in diameter.

deposit on the northeast coast. 
This species belongs in the group with Macaranga noblei Elm. 
and M. piperi Merr. but is at once distinguishable from both by 
its leaves being glabrous on the lower surface. It is less closely 
allied to M. amplifolia Merr., from which it is easily distinguished 
by its cordate leaves, its shorter inflorescences, and its entirelv 
glabrous leaves and petioles.
