  • Description

    Species Description - Tree or rarely a shrub, (2.5-)8-20 m tall, 25-60 cm in diam. Young twigs and petioles densely covered with greyish white, stellate scales 0.2-0.4 mm in diam. Petioles 2-5 mm long, 1-2 mm in diam. Lamina narrowly elliptic to elliptic (ovate-elliptic to oblong-elliptic), (4-)6-10(-14) cm long, (1.5-)2.5-4(-5.5) cm wide, leaf index 1.9-3, coriaceous, green, shiny above, green to greenish yellow below, glabrous above, sparsely to rather densely covered with greyish-white, stellate scales 0.2-0.4 mm in diam. below, base acute to attenuate, apex acute to shortly acuminate (acumen to 5 mm long), primary vein impressed above, secondary veins straight to curved, (8-) 10-15 on either side of primary vein, raised above, angles with primary veins (45-)50-70(-80)°, loop-forming at right to obtuse angles, loops distinct, smallest distance between loops and margin 2-4 mm, tertiary veins raised on both sides. Inflorescences among leaves, leaf-opposed or supra-axillary, 1-5-flowered. Indument: pedicels and outer side of bracts and sepals totally covered with greyish-white, stellate scales 0.2-0.4 mm in diam., inner side of sepals and both sides of petals totally to densely covered with greyish- white, stellate hairs 0.2-0.5 mm in diam., inner base of sepals and petals glabrous. Pedicels (5-) 10-25 mm long, 1-2 mm in diam., fruiting pedicels to 4 mm in diam. Upper bract at 1/2 to 3/4 of base of pedicel, debate to very broadly ovate, 1.5-3 mm long, amplexicaul. Flower buds broadly to very broadly ovoid, distinctly apiculate. Flowers green, maturing red in vivo, inner base of inner petals dark red. Sepals connate for 15-20%, triangular-ovate to broadly so, 9-16 mm long, 6-10 mm wide, acute to obtuse. Petals subequal, rhombic-elliptic to narrowly ovate, 14-23 mm long, 5-9 mm wide, acute to obtuse, inner base of inner petals callóse, strongly grooved. Stamens 1.1-1.3 mm long, dark red, apex of connective shallowly to very shallowly pyramidal, 0.2-0.4 x 0.6-0.8 mm, totally covered with simple hairs ca. 0.1 mm long. Carpels 2-2.5 mm long, ovary glabrous, upper part of stigma sparsely to densely covered with erect, simple to furcate hairs to 0.5 mm long. Fruit green, maturing red in vivo, subglobose, 4-6 cm in diam., basal collar composed of 7-14 connate, sterile carpels, 8-18 mm in diam., protruding or not below the fruit, fertile carpels 30-80, obtrulloid to obovoid, 20-30 mm long, 10-15 mm in diam., free, areoles shallowly pyramidal, 5-10 mm high, 4-6-ribbed, obtuse, apex blunt or apiculate (apicule 1-2 mm long), glabrous. Seeds obovoid, 18-22 mm long, 8-10 mm in diam., acute, yellowish-brown, dull.

  • Discussion

    According to the labels the fruit of this species is edible. Wood used for construction, etc. (Záchia, 1994).

    Duguetia lanceolata is similar to D. glabriuscula and D. lucida. With D. lucida it shares the shiny leaves and the high position of the upper bract; the two species differ in the size of the lamina: usually less than 10 cm long in D. lanceolata vs. usually much more than 10 cm long in D. lucida, and in the larger seeds (18-22 mm long in D. lanceolata, and 12-15 mm long in D. lucida). See further comments under D. glabriuscula.

    Additional data concerning D. lanceolata come from Záchia’s very detailed study of the Annonaceae of Rio Grande do Sul, Brazil (1994). He states that this species is characteristic for the Atlantic rain forests, but that it also occurs in periodically inundated (várzea) vegetation, and in campos cerrados.
