Guatteria elata R.E.Fr. (1938) 712; (1939) 499; Spichiger in Spichiger et al. (1989) 121, f. 56; Murillo A. & Restrepo (2000) 92, f. 24. — Type: Krukoff 8356 (holo S; iso A, BM, BR, F, G, K, MO, P, U, US 2 sheets), Brazil, Amazonas, Basin of Rio Solimões , Mun. São Paulo de Olivença, near Palmares, 11 Sept. to 26 Oct. 1936.
Tree or shrub 7–35 m tall, 15–45 cm diam; young twigs densely to sparsely covered with appressed hairs 0.2–2 mm long, soon glabrous. Leaves: petiole 5–10 mm long, 1–1.5 mm diam; lamina narrowly elliptic, rarely narrowly obovate, 8–17 by 2–5 cm (leaf index 2.8–4), coriaceous, not verruculose, dull above, dark brown to blackish brown above, brown to dark brown below, glabrous above, rather densely to sparsely covered with appressed hairs 0.5–1 mm long below, base attenuate, apex acuminate (acumen 5–20 mm long), primary vein impressed above, rounded to distinctly keeled below, secondary veins indistinct, 10–15 on either side of primary vein, slightly raised above, smallest distance between loops and margin 2– 5 mm, tertiary veins inconspicuous, flat above, reticulate to percurrent. Flowers in 1(–3)-flowered inflorescences in axils of leaves or on leafless branchlets; pedicels 10–25 mm long, c. 1 mm diam, fruiting pedicels to c. 3 mm diam, rather densely covered with appressed hairs, articulated at 0.2–0.4 from the base, bracts 5–6, soon falling (only scars seen); flower buds depressed ovoid; sepals free, broadly ovate-triangular, 4–6 by 5–6 mm, reflexed, outer side densely covered with appressed, greyish hairs; petals green, maturing cream or yellow in vivo, narrowly elliptic to elliptic or obovate, 20– 25 by 5 –12 mm, outer side densely covered with appressed hairs, particularly the base; stamens 1–1.5 mm long, connective shield papillate, umbonate or not. Monocarps 30–75, green, maturing black in vivo, black to brown in sicco, ellipsoid, 10–12 by 5 –6 mm, sparsely covered with appressed hairs, soon glabrous, apex apiculate (apiculum 0.1–0.5 mm long), wall 0.2–0.3 mm thick, stipes 15–25 by c. 1 mm. Seed ellipsoid, 8–11 by 4–6 mm, dark, shiny brown, pitted, raphe raised.
Distribution — Amazonian Colombia (Amazonas, Vaupés), Brazil (Amazonas), Peru (Loreto).
Habitat & Ecology — In non-inundated forest, on sandy to sandy-clayey soil. At elevations of up to 200 m. Flowering: July to March; fruiting: March, August to October, December.
Vernacular names — Peru: Carahuasca ( Daly et al. 5797, Daza 26, Valcarcel 399-2G, Vásquez et al. 7124, 9364), Cara- huasca negra (J. Ruiz 1074), Espintana (Spichiger et al. 1770).
Notes — Guatteria elata is recognizable by its brownish (in sicco!) lamina, an indistinct secondary leaf venation, an attenu- ate leaf base and an inconspicuous indument of appressed hairs on the lower side of the lamina.
A diameter of 15 feet is mentioned on the type label, which seems highly unlikely. Other label annotations we came across did not give bigger diameters than 45 cm .
One of the two Colombian collections, namely Zarucchi 1924 (U) from Mitú, Vaupés, probably belongs here, although it is aberrant in having relatively short stipes (5–15 mm vs 15–25 mm in normal G. elata ).
