Guatteria cryandra Erkens & Maas (2008) 404; Maas & Westra (2011) 118, f. 3b. — Guatteriopsis kuhlmannii R.E.Fr. (1937) 275, t. 8, not Guatteria kuhlmannii R.E.Fr. (1939) . — Type: J.G. Kuhlmann 2015 = RB 24361 (holo S; iso RB 4 sheets), Brazil, Pará, Rio Tucuruí, affluent of Rio Xingu, Vitória, 17 Apr. 1924.

Tree 3–10 m tall, c. 10 cm diam; young twigs densely covered with appressed hairs, soon glabrous. Leaves: petiole 2– 5 mm long, 1–2 mm diam; lamina narrowly elliptic to narrowly oblong-elliptic, 13–25 by 4–8 cm (leaf index 2.6–4.1), chartaceous, rather densely verruculose, pale greenish brown above, pale brown below, glabrous above, sparsely covered with appressed hairs below, the primary vein rather densely so, base obtuse to rounded, apex acuminate (acumen 15–25 mm long), primary vein flat to slightly raised above, secondary veins indistinct, 17–25 on either side of primary vein, slightly raised above, not or indistinctly loop-forming, smallest distance between loops and margin 1–4 mm, tertiary veins slightly raised above, reticu- late. Flowers in 1–2-flowered inflorescences in axils of leaves or on leafless branchlets; pedicels 1–5 mm long, 1–2 mm diam, fruiting pedicels to c. 5 mm long, c. 3 mm diam, densely covered with appressed, brown hairs, articulated at c. 0.2 from the base, bracts not countable with certainty, one bract seen: broadly ovate-triangular; flower buds broadly ovoid; sepals basally connate, broadly ovate-triangular, 5– 6 by 5 –6 mm, appressed, outer side densely covered with appressed hairs; petals yellow or golden yellow in vivo, broadly ovate to ovate, 10–15 by 8–10 mm, outer side densely covered with appressed, brown hairs; stamens c. 2 mm long, connective shield papillate. Monocarps 10–30, red to red-orange when ripe in vivo, blackish in sicco, ellipsoid, 9–12 by 4–6 mm, sparsely covered with appressed hairs, apex apiculate (apiculum 0.5–1 mm long), wall c. 0.2 mm thick, stipes 1–3 by c. 1 mm. Seed ellipsoid, 9–10 by 4 mm, pitted, raphe not distinct from rest of seed.

Distribution — Amazonian Brazil (Amapá, Pará).

Habitat & Ecology — In non-inundated forest, one specimen growing along river, often on clayey soil. At elevations of up to 250 m. Flowering: March, June, November; fruiting: August, September.

Vernacular names — Not recorded.

Note — Guatteria cryandra is characterized by shortly petiolate leaves with a rounded to obtuse base, in combination with the stiffly appressed hairs on the leaves and young branchlets, as well as with the shortly stipitate monocarps with stipes 1–3 mm long, and very short pedicels making the flowers appear almost sessile.
