This species has been confused in the herbarium with Mallotus leuco- 
calyx Muell.-Arg., but differs from that species not only in its distinctly 
alternate leaves, not in unequal pairs, but also in many other characters; 
it is probably most closely allied to Mallotus helferi Muell.-Arg. 
MALLOTUS AURICULATUS sp. nov. § Eumallotus. 
Arbor parva, partibus junioribus plus minusve ciliata; foliis 
longe petiolatis, usque ad 15 cm longis, oblongo-ellipticis vel 
late ovato-lanceolatis, chartaceis, subtus parce glandulosis, pen- 
ninerviis, acuminatis, basi angustatis, biauriculatis, auriculis 
brevibus, obtusis, supra glandulis 1 ad 3 instructis; nervis 
utrinque circiter 8, subtus prominentibus ; stipulis setaceis; in- 
florescentiis $ axillaribus, solitariis, spicatis; fructibus pubes- 
centibus, valde muricatis. 
A small tree reaching a height of about 5 m, the branchlets, 
inflorescences and under surfaces of the leaves with scattered, 
rounded, colored or pale, waxy glands. Branches terete, brown- 
ish, glabrous, the branchlets, petioles, and midrib and nerves on 
the under surface of the leaves with scattered, long, white, 
ciliate hairs, ultimately becoming nearly glabrous. Leaves al- 
ternate, oblong-elliptic to broadly ovate-lanceolate, 8 to 15 cm 
long, 2 to 6 cm wide, brownish or somewhat olivaceous when dry, 
paler beneath, slightly shining, firmly chartaceous, the margins 
obscurely and distantly repand-denticulate or subentire, the apex 
subcaudate-acuminate, the acumen blunt, often 2 cm long, the 
base narrowed, biauriculate, the auricles about 2 mm long, 
rounded, the sinus very narrow, each auricle with from one to 
three, prominent, dark-colored glands on the upper surface, the 
lower surface of the leaves with scattered, round, pale or colored, 
waxy glands; lateral nerves about 8 on each side of the midrib, 
curved-ascending, distant, prominent beneath, looped-anasto- 
mosing, the reticulations lax, prominent; petioles 2.5 to 5 cm 
long, when young ciliate, ultimately nearly glabrous; stipules 
setaceous, brown, acuminate, about 6 mm long. Staminate in- 
florescence axillary, solitary, spicate, the spikes about 5 cm 
long, pubescent, glandular, the bracteoles ovate to ovate-lanceo- 
late, acuminate, about 2 mm long, each subtending from one to 
several sessile or subsessile flowers. Calyx-segments obovate,
