MACARANGA Thouars 
MACARANGA ROBINSONII sp. nov. § Inermes. 
Arbor glabra circiter 8 m alta ; foliis chartaceis, oblongis, inte- 
gris, usque ad 16 cm longis, acuminatis, basi acutis vel obtusis, 
in pagina superiore 2-glandulosis, subtus eglandulosis, costa 
ciliata, nervis utrinque circiter 11, prominentibus, petiolo 2.5 
ad 5.5 cm longo; paniculis ? axillaribus, tenuibus, ut videtur 
paucifloris, usque ad 10 cm longis, bracteis minutis, lanceolatis, 
integris, eglandulosis ; fructibus glabris, inermis, globosis, 4 mm 
diametro, 1-locellatis. 
A glabrous tree about 7 m high. Branches and branchlets 
slender, terete, reddish-brown, glabrous, or the very young parts 
at the tip somewhat furfuraceous-lepidote. Leaves alternate, 
oblong, chartaceous, 10 to 16 cm long, entire, penninerved, oliva- 
ceous and somewhat shining when dry, the lower surface ciliate 
on the midrib, otherwise glabrous, apex slenderly acuminate, 
base acute to blunt, rather prominently 2-glandular on the upper 
surface near the insertion of the petiole, the lower surface a little 
paler then the upper, shining, not at all glandular ; lateral nerves 
about 11 on each side of the midrib, slender, prominent, curved- 
ascending, anastomosing; petioles 2.5 to 5.5 cm long. Pistillate 
panicles axillary, slender, apparently few-flowered, up to 10 cm 
long, the bracts lanceolate, acuminate, entire, eglandular, about 
1.5 mm long, the pedicels slender, about 5 mm long. Capsules 
globose, 5 mm in diameter, 1-celled, 1-seeded, dehiscent, glabrous 
or obscurely glandular. 
Amboina, Hitoe messen, Rel. Robins. 1721, November 5, 1913, in forests, 
altitude about 125 meters. 
A characteristic species apparently belonging in the section Inermes Pax 
& Hoffm., the three species placed here being from the Philippines and 
New Guinea. Of the three known species it is most closely allied to 
Mcicaranga inermis Pax & K. Hoffm. of New Guinea, from which it is 
distinguished by numerous characters, notably its differently shaped, nar- 
rower, prominently acuminate leaves, which are not glandular beneath, 
and its glabrous capsules. 
MACARANGA sp. 
Amboina, Way uri, Rel. Robins. 1722, September 9, 1913, on cliffs along 
rivers, altitude about 40 meters; locally known as picha piring puti. 
A characteristic species apparently belonging in the same group with, 
and allied to, Macaranga leytensis Merr. Unfortunately the specimen is 
very immature; the inflorescence is well formed, but not sufficiently de 
veloped to determine whether the plant is a pistillate or a staminate one.
