Probabiliter G. goudotianae proxima sed ab a differt venis secundariis impressis pedicellis longioribus et monocarpiis minoribus. — Typus: Cornejo & Montenegro 8355 (holo NY; iso U), Ecuador, Pichincha, Ayapi Pachijal , 1220 m, 18 Nov. 2010 .

Tree 7–20 m tall, 7–8 cm diam; young twigs densely to sparsely covered with appressed hairs, soon glabrous. Leaves: petiole 7–17 mm long, 2–2.5 mm diam; lamina elliptic, ovate, obovate or narrowly so, 10–24 by 4–9 cm (leaf index 2.1–3.1), coria- ceous, not verruculose, dull, rarely shiny, greyish green above, greyish green to greenish brown below, glabrous above, sparsely densely covered with appressed hairs to glabrous below, base acute to obtuse, sometimes attenuate, apex acuminate (acu- men 5–15 mm long) to acute, primary vein impressed above, secondary veins distinct, 12 –20 on either side of primary vein, impressed above, smallest distance between loops and margin 3–8 mm, tertiary veins raised above, reticulate. Flowers solitary in axils of leaves; pedicels 25–80 mm long, 1–1.5 mm diam, fruiting pedicels to 1.5 mm diam, sparsely to densely covered with appressed hairs, articulated at 0.1–0.3 from the base, bracts 5 – 6, not seen except for incidental foliaceous upper bracts, these narrowly elliptic to elliptic, 12–27 by 4–12 mm; flower buds not seen; sepals free, broadly ovate-triangular, 3–5 by 3–5 mm, appressed, but apex and margins often reflexed, outer side rather densely covered with appressed hairs; petals green to yellow in vivo, elliptic-ovate to narrowly so, 10– 20 by 4–11 mm, outer side densely covered with erect to appressed, curly hairs; stamens 2–2.5 mm long, connective shield papil- late. Monocarps 10– 50, green to purple in vivo, black in sicco, ellipsoid, 10–12 by 4–7 mm, glabrous or sparsely covered with appressed hairs, apex apiculate (apiculum <1 mm long) or rounded, wall 0.5–1{–1.5} mm thick, stipes 5–12 by 1 mm. Seed ellipsoid, 9–10 by 4–5 mm, brown, pitted to transversely grooved, raphe raised.

Note — Guatteria pichinchae probably comes closest to G. goudotiana , sharing coriaceous leaves and long pedicels. It differs by its impressed secondary veins (vs slightly raised in G. goudotiana ), much longer pedicels (25–80 vs 10–30 mm long) and by smaller monocarps (<12 mm vs to 20 mm long). Flower colour is reported in G. pichinchae to vary from green to yellow, whereas G. goudotiana is reported to have greyish to black petals.
