description: Ficus nebulosilvana N. Medina, sp. nov. (Figs. 1, 4A–D)   
 Type:— COLOMBIA. Nariño: Piedra Ancha, corregimiento Chucunez, Reserva Natural La Planada, 1650–1800 m, 1°10’N 77°58’W, 18 May 1991, Betancur et al. 2575 (holotype COL!, isotypes MO!, NY!, PSO!).   
 Ficus nebulosilvana is most similar to F. cuatrecasana from which it is easily distinguished by its reduced number of secondary veins, lack of intersecondary parallel veins and the smaller size of the leaves.   
 Trees or stranglers (vines?), up to ca. 25 m tall. Leafy twigs 5–6 mm diameter, glabrous to brown-tomentose; periderm persistent. Laminae coriaceous, bullate, ovate (sometimes elliptic), 8–15 × 5–8 cm, apex acuminate to cuneate, base truncate to subcordate (lobes up to 5 mm), margin entire; upper surface glabrous to puberulous; lower surface pubescent to occasionally glabrous and tomentose on the veins, hairs up to 3 mm in length, brown to yellow, erect; midrib and lateral veins prominent above, lateral veins 4–7 pairs, the basal pair up to 1/5–1/10 the length of the lamina, tertiary venation reticulate; waxy gland at the base of the midrib beneath; petiole 22–30 mm, 3–4 mm in diameter, glabrous to hirsute; stipules 10–15 mm long, sericeous, caducous. Figs axillary, born in pairs, sessile; basal bracts 2–3 mm long, persistent, sericeous to glabrous; receptacle globose, 8–13 mm in diameter when dry, glabrous to pubescent; ostiole ca. 3 mm in diameter, slightly prominent. Staminate flowers 1–1.5 mm pedicellate, tepals 3, 1– 1.4 mm long, stamens 1, anthers ca. 1 mm long. Pistillate flowers 0–2.5 mm pedicellate, tepals 3, 1.5–1.9 mm long; style 0–20 mm long; stigma ca. 0.2 mm long, bifid; ovary 0.9–1.1 mm long, asymmetrically reniform; interfloral bracts 1.8–2 mm.   
 Distribution and Habitat: — Ficus nebulosilvana is known only from the slopes of the western Andes in Colombia and Ecuador (Fig. 6), in Cloud Forests at 1300–2200 m elevation.   
 Vernacular Name: —Matapalo.   
 Conservation assessment:— Applying IUCN Red list categories (IUCN, 2001), Ficus nebulosilvana is categorized as Least Concern (LC), because of its wide extent of occurrence in western Colombia and its presence at several localities protected for conservation.   
 Etymology: —The specific epithet refers to the cloud forests habitat of the species.

 Discussion: — Ficus nebulosilvana closely resembles F. cuatrecasana Dugand (1942: 36). Both F. nebulosilvana and F. cuatrecasana present indumentum on the stipules, young branches, figs and leaves, but F. nebulosilvana is easily distinguished by its reduced number of secondary veins, lake of intersecondary parallel veins, and smaller leaves. Most of the specimens examined of F. nebulosilvana had been formerly determined as F. brevibracteata Burger (1973: 423) by C.C. Berg, however F. nebulosilvana differs from F. brevibracteata in leaf shape and habitat (see Table 1). The Ecuadorian specimens Silverstone-Sopkin et al. 9528, 9975 (CUVC!, MO!, BG, QCNE) are close to F. nebulosilvana in their leaf shape and habitat, but differ by their flattened venation and subpersistent stipules. Although the specimens McPherson 13394 (COL!, HUA!, MO!) and Barreto et al. 148 (MO!) are reported as vines, it is most likely that they are young stranglers rather than having a climbing habit. F. nebulosilvana may be distinguished from F. cuatrecasana and F. brevibracteata based on the characters listed in Table 1.
