Guatteria notabilis Mello-Silva & Pirani (1988) 44, f. 1–23. — Type: Mello-Silva et al. CFCR 8062 (holo SPF; iso BHCB,CEPEC,F, K, MO,NY, OWU, RB, SP, SPF 2 sheets, U), Brazil, Minas Gerais, Joaquim Felício, Serra do Cabral, road to Várzea da Palma , 1000 m, 31 Aug. 1985.

Tree 4–9 m tall, 5–30 cm diam; young twigs densely covered with erect, long-persisting, brown hairs, finally glabrous. Leaves: petiole 2–5 mm long, 1–3 mm diam; lamina narrowly oblong-elliptic, rarely elliptic, 10–20 by 3.5–6 cm (leaf index 2.5–3.4), coriaceous, densely verruculose, dull, greyish green to brown above, dark brown below, sparsely covered with erect hairs above, densely covered with erect, brown hairs below, base obtuse to rounded, extreme base slightly attenuate, basal margins slightly revolute, apex acute, obtuse, or shortly acuminate (acumen 2–5 mm long), the very apex revolute and mucronate (mucro 1–2 mm long), primary vein raised to flat above, secondary veins indistinct, 12–18 on either side of primary vein, flat above, smallest distance between loops and margin 2–4 mm, tertiary veins inconspicuous, flat above, reticulate. Flowers in 1–3-flowered, terminal inflorescences; pedicels 10–20 mm long, c. 2 mm diam, fruiting pedicels to c. 25 mm long, c. 3 mm diam, densely covered with erect hairs, articulated at c. 0.2 from the base, bracts 2, soon falling, sometimes foliaceous, elliptic to obovate-elliptic, 10–22 mm long; flower buds depressed ovoid; sepals free, broadly ovate-triangular, 10–15 by 7–11 mm, ap- pressed (but according to Pirani et al. CFCR 11147: reflexed and revolute), outer side densely covered with erect hairs; petals greenish, cream or reddish green in vivo, elliptic to broadly elliptic, 10–18 by 8–13 mm, outer side densely covered with erect hairs; stamens c. 1.5 mm long, connective shield papillate to hairy. Monocarps 15–30, reddish green in vivo, black in sicco, ellipsoid, 12–15 by 7–8 mm, densely covered with erect hairs, soon sparsely so, apex slightly apiculate (apiculum <1 mm long), wall c. 1 mm thick, stipes absent. Seed ellipsoid, c. 10 by 4 mm, dark brown, apex slighly pointed, rugulose, raphe not distinct from rest of seed.

Distribution — Brazil (Minas Gerais).

Habitat & Ecology — In campo rupestre vegetation, on rocky slopes.At elevations of 950–1300 m. Flowering: throughout the year; fruiting: throughout the year.

Vernacular names — Not recorded.

Note — Guatteria notabilis , one of the most beautiful species in the genus, cannot be confused with any species in the genus because of the combination of terminal 1–3-flowered

inflorescences, densely hairy leaves and flowers, almost sessile monocarps and densely verruculose leaves.
