  • Description

    Species Description - Tree, rarely a shrub, 2-30 m tall, to 40 cm in diam. Young twigs and petioles totally to rather densely covered with whitish to light brown stellate scales 0.2-0.5 mm in diam., tardily becoming glabrous with age. Petioles 2-7 mm long, 1-2 mm in diam. Lamina elliptic to narrowly elliptic (rarely ovate), (6-)8-24 cm long, (2-) 3-8 cm wide, leaf index (2.5-)3-3.6(-4.5), coriaceous, brown or brownish green, distinctly shiny above, pale brown or brownish green below, glabrous above (except for primary vein with stellate hairs at base), rather densely to totally covered with whitish stellate scales 0.1-0.5 mm in diam. below, base acute, apex acute to (shortly) acuminate, primary vein impressed (rarely flat) above, secondary veins curved, abruptly curved or straight, (6-) 10-20 on either side of primary vein, slightly raised to prominent above, angles with primary vein (45-)60-70(-85)°, loop-forming at acute to right angles, loops indistinct, smallest distance between loops and margin (1-)2-4(-5) mm, tertiary veins slightly raised or prominent above. Inflorescences among leaves (rarely persisting on older branchlets), leaf-opposed, supra-axillary, or sub-axillary, or sometimes terminal, terminal on a short axillary shoot, or near the base of a lateral shoot, a single rhipidium, or often composed of 2-several rhipidia. Rhipidia 1-several-flowered, to 15 flowers in succession. Indument: pedicels and outer side of bracts, sepals and petals totally covered with stellate scales 0.2-0.4 mm in diam., inner side of sepals and petals totally covered with stellate hairs 0.2-0.4 mm in diam., basal inner half of sepals and basal inner third of inner petals glabrous. Peduncle 1-2(-3) mm long, 1.5 mm in diam., to 4 mm in diam. in fruit. Sympodial rachis to 10 mm long. Pedicels (3-)5-15 mm long, 1 mm in diam., to 5 mm in diam. in fruit (to 7 mm in diam. just below the fruit). Upper bract closely below the flower, rarely at 3/4 of the pedicel, broadly to depressed ovate, amplexicaul, 3-5 mm long, obtuse to minutely apiculate, more or less persistent. Flower buds ovoid. Flowers green, maturing cream to yellow, with red inner base in vivo. Sepals connate for <15%, ovate to broadly ovate, 7-14 mm long, 4-7(-10) mm wide, apex acute to acuminate. Petals subequal, ovate to narrowly obovate, 10-20 mm long, 4-7 mm wide, inner base of inner petals callose. Stamens 0.8-1.3 mm long, red, apex of connective discoid, 0.2-0.3 x 0.5 mm, apiculate, densely covered with minute hairs. Carpels 1.5-2.2 mm long, ovary and stigma densely covered with stellate or simple hairs up to 0.5 mm in diam. to glabrous. Fruit green maturing orange to red in vivo, globose to subglobose, 4.5-5.5 cm in diam., basal collar composed of 13-18 connate, sterile carpels, slightly to manifestly protruding below the fruit, 8-10 mm in diam., fertile carpels 80-115, obovoid to obtrulloid, 16-22 mm long, 4-14 mm in diam., fused to 10% of their length, ultimately falling apart, areoles broadly ovoid, 4-11 mm high, obtuse, apiculate (apicule 0-1.5 mm long), polygonal, surface smooth to slightly striate, totally to sparsely covered with stellate scales (or stellate hairs) about 0.1 mm in diam., or glabrous. Seeds ellipsoid to obovoid, 12-15 mm long, 4-8 mm in diam., obtuse to rounded, smooth, dark brown, shiny.

  • Discussion

    Bark used for fishing (Steyermark 62411).

    Duguetia lucida can be recognized at first glance by its distinctly shiny leaves, and often by flowers with the upper bract placed immediately below the sepals. It is similar to D. lanceolata and D. glabriuscula, and UPGMA analysis brings the three into one cluster (Fig. 37, 7th cluster). See also the notes with D. lanceolata.

    Some of the Bolivian collections cited above, and the Brazilian collections from the state of Rondônia are aberrant in having a lower side of the lamina which is sparsely hairy instead of totally to rather densely so (specimens marked with an asterisk). In general aspects, however, these specimens seem to match the concept of D. lucida satisfactorily.

  • Distribution

    Trinidad, Venezuela, Guyana, Brazil (Acre, Rondônia, Roraima), and Bolivia. In non-inundated forest, sometimes on slopes. From sea level up to elevations of 1200 m. Flowering throughout the year, but often between February and April, fruiting throughout the year.
