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 OVATIFOLIA 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.

This species belongs in the group with Macaranga noblei Elm. 

 and M. piper'i 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 entirely 

 glabrous leaves and petioles.
