    Brazil, Bahia, Jussari, RodoviaJussari-Palmira, RPPN Serra do Teimoso, 15°09′15.2′′S, 39°31′26.2′′W, 300 – 350 m, 3 July 2005, E. G. Gonçalves, J. Jardim, V. C. Souza & H. Lorenzi 1296 (holotypus CEPEC; isotypus UB).
    Habit
    Epilithic herb
    Stem
    Stem decumbent, thick, internodes short, less than 3 mm long, 3 – 4 cm in diameter, cataphylls chartaceous to subcoriaceous, lanceolate, 4 – 6 cm long, 0.6 – 0.8 cm wide, soon withering and persisting as fibres, producing roots with whitish trichomes
    Leaves
    Leaves erect, petiole 10 – 14 cm long, 0.4 – 0.5 cm in diam., “U” shaped with or without a narrow keel abaxially, sulcate with acute margins adaxially, geniculum thicker than petiole, curved, 1.5 – 2 cm, leaf blade broadly lanceolate, subcoriaceous, dark green and semi-glossy adaxially, pale matt green abaxially; base obtuse to truncate, apex acute to acuminate, 30 – 60 × 9 – 23 cm; primary lateral veins 15 – 16 per side; departing the midrib at 30 – 40° angle and joining together in a collective vein about 5 – 14 mm from leaf margin; midrib with a median abaxial keel; primary lateral veins and collective veins only poorly visible on both surfaces, minor venation not visible
    Inflorescences
    Inflorescence erect at anthesis, usually shorter than leaves; peduncle 28 – 30 cm long, 0.4 – 0.8 cm in diam., 0.9 times to 3.8 times as long as petiole, occasionally keeled abaxially; spathe subcoriaceous to coriaceous, usually held over the spadix, elliptic, green with purplish margins, 8 – 9 cm long, 2.5 – 3 cm wide, inserted at 43 – 48° angle on the peduncle, apiculate at apex, cuneate at base; spadix usually shorter than spathe, green to purplish, shortly stipitate, stipe up to 3 mm long, 8 – 10 cm long, 0.5 – 0.8 diam. at middle, tapering to the apex; flowers (when viewed from above) rhombic, 2.5 – 3 × 3 mm in both directions, sides slightly sigmoid; 7 – 9 flowers visible in principal spiral, 5 – 6 in alternate spiral, tepals matt, lateral tepals 2 mm wide, inner margins convex, outer margins 2-sided, pistils slightly emergent, obovoid, stigma rounded; stamens partially obscuring the pistils, weakly exserted, filaments flattened, translucent, 0.5 – 1 mm, anthers whitish yellow, 1 – 1.2 × 1 mm, thecae oblong 1 – 1.2 × 0.5 mm
    Infructescences
    Infructescence pendent, with persistent spathe, spadix 8 – 10 cm long, 0.8 – 1.1 cm diam., berries medium green at apex, more translucent at base, broadly obovate, 6 – 7 × 5 – 6 mm; seed ovoid, cream-coloured with minute brown dots, 3 – 4 × 3 – 4 mm
    Distribution
    This species is so far known only from the type locality.
    Ecology
    Anthurium molle occurs epilithically under the forest canopy. It is much rarer locally than A. teimosoanum and is usually found close to the summit of the hills, whereas A. teimosoanum is common in areas of forest at lower altitudes.
    Conservation
    The poor state of floristic knowledge about the South Bahian drier forests indicates that conservation status of Anthurium molle should be considered as Data Deficient (DD), as defined by IUCN (2001).
    Note
    Anthurium molle is tentatively placed in sect. Urospadix Engl. subsect. Obscureviridia because of the thick leaves with poorly visible veins. The same criterion has recently been used to include A. viridispathum E. G. Gonç., also from eastern Brazil (Gonçalves 2005), in this subsection. However, these species seem to be part of a complex including other east Brazilian species like A. coriaceum (Graham) G. Don and A. xanthophylloides G. M. Barroso, both currently placed in sect. Pachyneurium (Croat 1991; Gonçalves & Salviani2001). Other species such as A. cleistanthum G. M. Barroso and A. brachypodum G. M. Barroso may also belong here. The epithet (from the Latin molle = soft) alludes to the flaccid texture of the leaves, which are usually stiff and coriaceous in other species of subsect. Obscureviridia. This new species is similar to Anthurium viridispathum but differs in having proportionally longer petioles, a cordate leaf blade and much softer leaves.
