Guatteria elegantissima R.E.Fr. (1950a) 338, pl. 4. — Type: Cuatrecasas 17305 (holo S; iso COL 2 About COL sheets, F 2 sheets, L, U, US), Colombia, Valle del Cauca, Costa del Pacífico, Río Cajambre , San Isidro , 5–100 m, 2–5 May 1944.
Tree 5–25 m tall, 5–80 cm diam; young twigs somewhat zig- zagging, densely covered with long-persisting, erect, brown hairs. Leaves: petiole 1–3 mm long, 1–2 mm diam; lamina narrowly elliptic to narrowly ovate, 7–22 by 2–3.5 cm (leaf index 3.8–5.8), chartaceous, densely verruculose, dull, dark brown or dark green above, paler brown or green below, glabrous above, but the primary vein densely covered with erect, brown hairs, densely covered with erect, brown hairs below, base acute, rarely obtuse, apex acuminate (acumen 5–20 mm long), primary vein impressed above, secondary veins indistinct to distinct, 12– 20 on either side of primary vein, flat to slightly impressed above, more or less forming a marginal vein, at a smallest distance of 1–3 mm fom the margin, tertiary veins inconspicuous, flat to slightly raised above, reticulate. Flowers in 1–2-flowered inflorescences in axils of leaves; pedicels 20–40 mm long, 1–1.5 mm diam, fruiting pedicels to c. 3 mm diam, rather densely to densely covered with erect, brown hairs, articulated at c. 0.3 from the base, bracts 3–6, soon falling, the basal ones 10–14 mm long, the 2 upper ones 13–16 mm long; flower buds depressed ovoid; sepals free, broadly ovate-triangular, 5–7 by 5–6 mm, appressed, outer side sparsely covered with appressed, brown hairs; petals green or yellow in vivo, broadly ovate to ovate, 9–13 by 7–10 mm, outer side densely covered with erect, brown hairs to almost glabrous, except for the hairy margins; stamens c. 1.5 mm long, connective shield papillate. Monocarps 40–50, dark green, maturing black in vivo, blackish in sicco, narrowly ellipsoid to ellipsoid, 5–8 by 2–4 mm, glabrous, except for a few scattered, appressed hairs, apex acute to apiculate (apiculum 0.1–0.2 mm long), wall 0.1–0.5 mm thick, stipes 2–5 by c. 1 mm. Seed narrowly ellipsoid, 6–8 by 2–4 mm, dull, dark brown, rugulose, raphe not distinct from rest of seed.
Distribution — Pacific coast of Colombia (Valle del Cauca).
Habitat & Ecology — In wet, tropical rain forest, along the margin of rivers and along roads, on loamy to clayey soil. At elevations of 0– 350 m. Flowering: February to August; fruiting: February, April, May, July, August, October.
Vernacular names — Colombia: Cargadero (Gentry et al. 48326), Cargadero negro (D.A. Sánchez S. 676).
Notes — Guatteria elegantissima can very easily be recognized by the very densely verruculose and shortly petiolate leaves which are densely covered with erect, brown hairs on the lower side. Moreover, the monocarps are quite characteristic in often being narrowly ellipsoid and shortly stipitate. Guatteria elegantissima looks somewhat similar to G. cuatrecasasii , differing by smaller leaves and a less dense indument of shorter hairs than in G. cuatrecasasii .
Wisum et al. 24 (MO) from Ecuador, Morona-Santiago occurs at quite some distance from Valle del Cauca in Colombia were all other gatherings were done. It is also remarkable because it occurs at an elevation of> 1200 m while in Colombia collections were found at elevations below 400 m. Apart from this it matches well the other material albeit with slightly larger monocarps .
