Type:— BRASIL. Acre: Senador Guiomard, Fazenda Experimental Catuaba , BR 364   , Km 35, 10°04’ S, 67°37’ W, 17 April 2010, H GoogleMaps   . Medeiros et al. 391 (holotype SP!, isotype NY, UFACPZ, RB!)   .

Diagnosis:— Folia elliptica   , glabra, apicibus acuminati. Receptacula pedunculata   , obovata, ostiolum elevatum, tubiforme.

Description:— Tree to 12 (–35) m tall or hemi-epiphytic. Leafy twigs 3–5 mm thick, glabrous; periderm persistent. Lamina (sub)coriaceous, elliptic, 6–14 x 3–6 cm, base acute to cuneate, apex acuminate; both surfaces glabrous; midrib reaching the apex of the lamina; lateral veins brochidodromous, 8–11 pairs, the first pair of lateral veins diverging from the midrib at an 45–50° angle, with one glandular spot at the base of the midrib beneath; tertiary venation reticulate; petiole 2–3.5 cm long, ca. 1 mm thick, glabrous, the epidermis persistent; stipules 3–7 mm long, glabrous or sparsely and minutely puberulous, caducous. Figs axillary, in pairs, greenish; peduncle 0.4–1 cm long; epibracts 1–1.5 mm long, persistent, the apex rounded to obtuse; receptacle rounded to obovate, 5–7 mm in diameter when dry, glabrous, yellowish to greenish, reddish at maturity, maculate, whitish to brownish spots; ostiole tubular, straight, 2–4 mm long, 1–2 mm in diameter, deeply crateriform. Staminate flowers with pedicels absent to very short, with a triangular basal bract ca. 1 mm long; perianth ca. 1 mm long, glabrous, with 3 basally connate tepals; stamens 1, the anthers ca. 1 mm long. Long pistillate flowers with pedicels 1–1.5 mm long; tepals 3, basally connate, 1–1.5 mm long, glabrous; style 0.5 mm long, lateral, the stigma simple, plumose; interfloral bracts up to 0.5 mm, triangular, glabrous. Short pistillate flowers sessile or subsessile, 0.5–1 mm long. Figure 1 View FIGURE 1 .

Distribution and Habitat:— North of Amazonas, Acre to West-central Peru and also from West to Northwest of Bolivia, at elevations between 185–450m altitude in disturbed areas or in forests nearby watercourses.

Vernacular Name:— Apuí (BRA), renaco blanco (PER).

Etymology:— The epithet refers to the tubular format of the ostiole.

Discussion:— Ficus pertusa   complex proposed by Berg (1981) is characterized by species with maculate figs with the ostiole sunken in the receptacle and leaves varying from small to medium-sized. Berg (2007) separates this complex in informal entities: ‘pertusa-form’, ‘subtriplinervia-form’, ‘padifolia-form’, ‘arpazusa-form’, ‘broadwayiform’ and ‘trachelosyce-form’, the latter with small to large figs of which the apex is protracted up to 1 cm long, distributed from Central America to north-western South America.

F. tubulosa   is also included in F. pertusa   complex, but it is morphologically closest to F. trachelosyce   , differing from the latter one by its obovate syconium with tubular ostiole ( Fig. 2 View FIGURE 2 , Tab. 1).

The entire Ficus pertusa   complex occurs from southern Mexico through Central America to Jamaica and in South America to western Ecuador, the Guianas, eastern Brazil, and Paraguay. Ficus pertusa   occurs in all these areas, in evergreen to deciduous forest, at altitudes up to 2000 m, whereas Ficus trachelosyce   occurs from Colombia to Costa Rica up to 400 m and F. tubulosa   from north of Amazonas, Acre to west-central Peru and also from west to northwest of Bolivia, in woodland, Igapó forest and river banks, in altitudes up to 450 m ( Fig. 3 View FIGURE 3 ).

Re-establishment of Ficus trachelosyce   :— Ficus trachelosyce Dugand   was informally treated by Berg (1981) as Ficus pertusa   L. ‘trachelosyce-form’. During the Flora of Venezuela, Berg (2000) officially treated this species as synonym of F. pertusa   . However, the characteristics identified by the author and the analyzes of both type materials enabled us to re-establish F. trachelosyce   as distinct species from F. pertusa   . The main characteristics that distinguish them are related to the structure of the inflorescence: F. pertusa   has globose syconium with umbilicate ostiole, while F. trachelosyce   has globose syconium with infundibuliform ostiole. For these characteristics we re-establish F. trachelosyce   as a valid species.
