Staminate flowers with pedicels absent to very short, with a triangular basal bract ca. 1 mmlong; perianth ca. 1 mmlong, glabrous, with 3 basally connate tepals; stamens 1, the anthers ca. 1 mmlong. Long pistillate flowers with pedicels 1–1.5 mmlong; tepals 3, basally connate, 1–1.5 mmlong, glabrous; style 0.5 mmlong, lateral, the stigma simple, plumose; interfloral bracts up to 0.5 mm, triangular, glabrous. Short pistillate flowers sessile or subsessile, 0.5–1 mmlong. Figure 1.   Distribution and Habitat:—North of Amazonas, Acre to West-central Peruand also from West to Northwest of Bolivia, at elevations between 185–450maltitude 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.  Additional specimens examined:—  BOLIVIA. Depto La Paz: Provincia Abel Iturralde, Parque Nacionaly Area Natural de Manejointegrado Madidi, Laguna Chalalán, entrando 45 min sobre orilla izquierda de río Tuichi, 14°26’S, 67°55’W,  450 m,  25 April 1997,  N. Y .   Paniagua Zambrana1242( BG!, LPB). Provincia Franz Tamayo, Parque Nacional Madidi, laguna Chalalán, bosque amazônico preandino inundable, 14°25’30’’S, 67°55’16’’W,  300 m,  26 September 2006,  A. A .   Murakami.et al. 3150( BG!, BOLV, LPB, MA, MO, USZ). Depto Pando: Provincia Nicolás Suarez, Cementeriogeneral de Cobija,  15 September 2005,  G .   Torrico1899( BG!, UAP).  BRAZIL. Acre: Plácido de Castro, margem esquerda do Rio Abunã,  13 May 2001,  L. G .  Lohmann& E. C.   de Oliveira491( BG!). Xapurí, Seringal Cachoeira, BR 317, ramal Cachoeira, 16kmao longo do ramal, 10°55’49’’ S, 68°13’54’’W,  03 May 2010,  H .   Medeiroset al. 638( RB, SP!). Amazonas: Itu, Rio Acre,  04 November 1923,  J. G .   Kuhlmann756( INPA!, RB!). Maraã, Rio Jupurá,  01 November 1982,  I. L .   Amaralet al. 276( INPA!).  PERU. Depto. San Martín: Província Mariscal Caceres, Distrito de Campanilla, margen izquierda del río Huallaga,  12 August 1970,  J .   Schunke4241( IAN!).   Discussion:—  Ficus pertusacomplex 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 cmlong, distributed from Central America to north-western South America.   F. tubulosais also included in  F. pertusacomplex, but it is morphologically closest to  F. trachelosyce, differing from the latter one by its obovate syconium with tubular ostiole ( Fig. 2, Tab. 1).   TABLE 1.Main characters distinguishing  Ficus tubulosafrom  F. pertusa, and  F. trachelosyce.     Character/Species   F. tubulosa   F. pertusa   F. trachelosyce  Angle of divergence between the middle lateral veins and the midrib 45–50° 40–50° 65–70°  Format of the syconium obovate globose globose  Diameter of the syconium 5–7 mm up to 6 mm 10–12 mm  Length of peduncle 4–10 mm up to 3 mm 2–3 mm  Format of the ostiole tubular umbilicate infundibuliform  Length of the ostiole 2–4 mm up to 1.5 mm 2–2.5 mm The entire  Ficus pertusacomplex occurs from southern Mexicothrough Central America to Jamaicaand in South America to western Ecuador, the Guianas, eastern Brazil, and Paraguay.  Ficus pertusaoccurs in all these areas, in evergreen to deciduous forest, at altitudes up to 2000 m, whereas  Ficus trachelosyceoccurs from Colombiato Costa Ricaup to 400 mand  F. tubulosafrom north of Amazonas, Acre to west-central Peruand also from west to northwest of Bolivia, in woodland, Igapó forest and river banks, in altitudes up to 450 m( Fig. 3).  Re-establishment of  Ficus trachelosyce:—  Ficus trachelosyceDugandwas informally treated by Berg (1981)as  Ficus pertusaL. ‘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 typematerials enabled us to re-establish  F. trachelosyceas distinct species from  F. pertusa. The main characteristics that distinguish them are related to the structure of the inflorescence:  F. pertusahas globose syconium with umbilicate ostiole, while  F. trachelosycehas globose syconium with infundibuliform ostiole. For these characteristics we re-establish  F. trachelosyceas a valid species.
