71. Guatteria galeottiana Baill. — Map 16

Guatteria galeottiana Baill. (1868b) 268; R. E.Fr. (1939) 373, f. 10b–d. — Type: Liebmann 16 (holo C; iso P), Mexico, Oaxaca, Comaltepec , Aug. 1842 .

Tree 2–10 m tall, 10–20 cm diam; young twigs sparsely covered with appressed hairs, soon glabrous. Leaves: petiole 4–8 mm long, 1–2 mm diam; lamina narrowly elliptic, rarely obovate, 10–15 by 3–5 cm (leaf index 3–3.3), chartaceous, not verruculose, shiny, often bright green when dry above and below, glabrous above, glabrous below, except for some hairs along the primary vein, base attenuate, apex acuminate (acumen 10–20 mm long), primary vein flat above, secondary veins dis- tinct, 8–15 on either side of primary vein at almost right angles, slightly raised above, smallest distance between loops and margin 2–4 mm, tertiary veins raised above, reticulate. Flowers solitary in axils of leaves; pedicels 10–30 mm long, c. 1 mm diam, fruiting pedicels 35–50 mm long, c. 2 mm diam, sparsely covered with appressed hairs to glabrous, articulated at c. 0.2 from the base, bracts 5–7, soon falling; flower buds depressed ovoid; sepals free, broadly ovate-triangular, 4–5 by 4–5 mm, reflexed, outer side rather densely covered with appressed hairs; petals yellowish green to yellow in vivo, ovate, 12–15 by 6–7 mm, outer side rather densely covered with appressed hairs; stamens 1–2 mm long, connective shield papillate. Monocarps 10– 20, green, maturing blackish purple in vivo, black in sicco, narrowly ellipsoid, 10–13 by 5–6 mm, sparsely covered with appressed hairs, soon glabrous, apex apiculate (apiculum <0.5 mm long), wall c. 0.2 mm thick, stipes 9–17 by 1 mm. Seed ellipsoid, 9–12 by 4–5 mm, dark brown, rugose, raphe not distinct from rest of seed.

Distribution — Mexico (Oaxaca, Veracruz).

Habitat & Ecology — In forest (‘selva alta perennifolia’). At elevations of 0–1400 m. Flowering: June, October, November; fruiting: February, April, November.

Vernacular names — Mexico: Peseʉ (Zoque language), Zapote de monte ( Osorio et al. 17, Rincón G. et al. 700).

Note — Guatteria galeottiana is an endemic from the Veracruz and Oaxaca regions in Mexico. It can be recognized by its leaves that often dry bright green, its long pedicels, the narrowly ellipsoid and apiculate monocarps, and its almost perpendicular secondary venation. All these characters fit the type very well. However, the collections from Oaxaca (e.g., H. Hernández G. 1695) differ somewhat by having rounder monocarps and a somewhat more ascending secondary venation, but otherwise fall within the description of this species .
