2-119.1. Licania stewardii Prance, Brittonia 28:
223, fig. 9. 1976. Type. Brazil. Amazonas:
Manaus-Caracarai Rd., km 130, 13 Feb 1974
(fl), Steward et al. P20251 (holotype, INPA;
isotypes, FHO, NY, US).
Small tree 3-5 m tall, the young branches puberulous,
soon glabrate. Leaf lamina oblong,
chartaceous, 4-8 x 2.2-4 cm, rounded or subcordate
at base, rounded, acute or retuse at apex,
glabrous above with a waxy lanate appressed pubescence
beneath; midrib slightly impressed
above, prominent beneath; primary veins 7-9
pairs, plane above, prominent beneath, the secondary
venation conspicuously reticulate; petioles
1.5-2.5 mm long, terete, eglandular, tomen-
tellous when young. Stipules linear, 2-3 mm long,
persistent, tomentellous, adnate to petioles. Inflorescences
of terminal or subterminal little
branched racemose panicles or simple racemes
2-7 cm long; rachis and branches gray-tomentellous.
Bracts and bracteoles narrowly lanceolate,
1-2 mm long, tomentellous on exterior, persistent.
Flowers 3-3.5 mm long. Receptacle
campanulate, gray-tomentellous on exterior, lanate
within; pedicels 0.25-0.5 mm long. Calyx
lobes five, acute, gray-tomentellous on exterior,
puberulous within. Petals absent. Stamens 9-11,
inserted around complete circle, shorter than calyx
lobes; filaments connate at base, the united
part lanate. Ovary densely lanate. Style equalling
filaments. Fruit unknown.
Distribution (Fig. 80). This species is known
only from the vicinity of the type locality where
it was very common in low campina forest around
a sandstone rock outcrop in an area where the
original forest has now been destroyed.

Tocantins, Tucurui, Breu Branco, 11 May 1978
(fl), M. G. Silva & R. Bahia 3508 (holotype,
MG; isotypes, INPA, NY). Fig. 82.
Tree 20 m tall, the young branches sparsely
puberulous, soon glabrate. Leaf lamina elliptic,
chartaceous, 8-15 x 3.5-7.2 cm, subcuneate at
base, acuminate at apex, the acumen 7-12 mm
long, glabrous above, with stomatal cavities filled
by dense lanate pubescence beneath; midrib plane
or slightly impressed above; petioles 4-6 mm
long, with two large conspicuous glands when
young, canaliculate, tomentellous when young,
becoming glabrous and rugulose with age. Stip-
ules triangular, ca. 5 mm long, ca. 2.5 mm broad
at base, inserted on base of petioles, persistent.
Inflorescences of terminal and subterminal racemose
panicles, the rachis and branches puberulous.
Bracts and bracteoles 1-2 mm long,
triangular, persistent, puberulous on both surfaces.
Flowers ca. 1.5 mm long, sessile on primary
branches of inflorescence. Receptacle campanulate,
sessile, tomentose on exterior and
within. Calyx lobes five, acute, puberulous on
both surfaces. Petals absent. Stamens three, unilateral;
filaments shorter than calyx lobes, glabrous.
Ovary inserted at base of receptacle, pilose.
Style equalling filaments, hirsute threefourths
of length. Fruit pyriform ca. 2 cm long
(5 cm stipe); exocarp ferrugineous-pubescent;
mesocarp thin; endocarp hard, granular, 1 mm
thick.

This species is most closely related to Licania
triandra, from which it differs in the thinner,
chartaceous leaves with deep stomatal cavities
covered by a lanate pubescence, which also ex-
tends over the venation, making the cavities much
less conspicuous than in L. triandra. It also dif-
fers in the broader stipules adnate to the petiole
and in the petiole rather than leaf bases glan-
dular.
