Monogr. 9: 137. 1972. Fig. 32.
Until recently this species was known only from
the Spruce type. The material cited below keys
to L. crassivenia and is included there for the
present, but has much larger leaves than the type
(10-13 x 4-5.5 cm as Distr., Falawatra, Nov 1971 (fl), Jimenez-Sda
1549 (holotype, NY; isotype, LBB 14282).
Tree to 26 m tall, the young branches tomentellous
soon becoming glabrous. Leaf lamina oblong-elliptic,
chartaceous, 14-19 x 6-7.5 cm; base
subcuneate, apex acuminate, the acumen 10-18
mm long, glabrous above, densely lanate beneath,
deeply reticulate venation beneath; midrib
impressed above, tomentellous towards base,
prominent beneath; secondary veins 9-11 pairs,
plane above, prominent beneath; petioles 15-20
mm long, weakly canaliculate, shortly tomentellous,
with two to many glands towards base.
Stipules not seen. Inflorescences of terminal and
axillary panicles, ca. 2.5 cm long; rachis and
branches tomentellous. Bracts and bracteoles
ovate-lanceolate, 0.6 mm long, persistent, pubescent.
Flowers 1.5 mm long. Receptacle campanulate,
tomentellous on exterior, tomentose
within; pedicels 0.4 mm long. Calyx lobes five,
tomentose. Petals absent. Stamens seven, unilateral,
included, three large and fertile, four
smaller and sterile; filaments glabrous, free to
base. Ovary lanate-pubescent. Style lanate. Fruits
pyriform, to 5 cm long including stipe of 1.5-2
cm; exocarp velutinous, ferrugineous-pubescent;
mesocarp thin; endocarp 1 mm thick, hard and
fibrous, sparsely hirsute within.
Distribution (Fig. 50). Known only from the
rain forests of Guyana and Surinam.
