Guatteria slateri Standl. (1929) 206; R. E.Fr. (1939) 517. — Type: Cooper & Slater 177 (holo F; iso GH, NY), Panama, Chiriquí, Progreso , July–Aug. 1927 .
Tree 4–30 m tall, to c. 30 cm diam; young twigs often zigzag- ging, rather densely covered with appressed, brown hairs, soon glabrous. Leaves: petiole 4–20 mm long, 1–3 mm diam, decurrent as slightly prominent ridges in young twigs; lamina narrowly elliptic to narrowly obovate, 7–24 by 2.5–8.5 cm (leaf index 2.7–3.2), chartaceous to coriaceous, not verruculose, dull, greyish green to dark brown above, brown below, glabrous above, sparsely covered with appressed, brown hairs to glabrous below, base acute to attenuate, apex acuminate (acumen 5–15 mm long), primary vein slightly raised to flat above, often keeled below, secondary veins distinct, 8–15(–20) on either side of primary vein, raised above, smallest distance between loops and margin 1–2 mm, tertiary veins raised above, reticulate. Flowers in 1(–2)-flowered inflorescences in axils of leaves; pedicels 15–32 mm long, 1–2 mm diam, fruiting pedicels up to c. 40 mm long, rather densely to sparsely covered with appressed hairs, articulated at c. 0.3 from the base, bracts 5–8, soon falling, basal bracts broadly to very broadly elliptic, 1.5–2.5 mm long, uppermost bracts obovate to elliptic, 7–8 mm long, occasionally the third bract from above foliaceous, 22– 26 mm long; flower buds depressed ovoid; sepals free, broadly ovate-triangular, 3–6 by 3–7 mm, apically reflexed or appressed, outer side sparsely covered with appressed hairs to glabrous; petals green, maturing yellow in vivo, ovate, obovate to rhombic, 8–16 by 5–11 mm, outer side sparsely to densely covered with appressed hairs; stamens 1.5–2 mm long, connective shield papillate to hairy. Monocarps 20–60, green, maturing red to finally black in vivo, black in sicco, ellipsoid, 8–10{–13} by 5–8 mm, sparsely covered with appressed hairs, soon glabrous, apex apiculate, sometimes rounded (apiculum <1 mm long), wall 0.1–0.2 mm thick, stipes 3–10 by 1–2 mm. Seed ellipsoid, 7–10 by 5–7 mm, dark brown, transversely grooved to pitted, raphe not distinct from rest of seed.
Distribution — Panama.
Habitat & Ecology — In primary wet forest or montane (elfin) forest.At elevations of (0–) 600–2100 m. Flowering: throughout the year; fruiting: throughout the year.
Vernacular name — Panama: Malagueto prieto.
Notes — Guatteria slateri is a species mostly found at high elevations, although the type has been collected at sea level. It has many features in common with G. costaricensis , the main differences being the shorter stipes (3–6 vs 8–14 mm), longer petioles (4–20 vs 3–7 mm) and longer pedicels (15–32 vs 10–20 mm). Another difference is found in the upper leaf side, which is glabrous in G. slateri , whereas the primary vein is covered with hairs in G. costaricensis .
Ripe monocarps are rarely found in this species, except for Maas et al. 9513, with monocarps (measured from spirit mate- rial!) of 10–13 mm long, thus somewhat longer than cited in the description based on herbarium collections.
