    Habit
    Terrestrial herbs
    Stem
    Stem short, thick, decumbent with an erect apex, internodes 0.2 – 0.3 × 2.5 – 6 cm; roots greyish white, numerous; prophylls and cataphylls chartaceous, triangular 4 – 9 × 2 – 3.2 cm, persisting as fibres
    Leaves
    Leaves 6 – 8 per plant, petioles 16.5 – 59 cm long, 0.4 – 0.6 cm diam., subterete, narrowly and obtusely sulcate adaxially, with rounded margins, dark matt green, minutely speckled in pale green, geniculum 1 – 1.3 × 0.6 – 0.8 cm, thicker than the petiole, sheath up to 1.5 cm; blade coriaceous, elliptic, usually oblique, cuspidate at apex, obtuse then shortly decurrent at base, 19 – 36 × 8 – 13 cm, broadest at middle, upper surface matt, dark green, lower surface medium matt green, midrib rounded below, rounded above, primary lateral veins 14 – 16 per side, almost indistinct from interprimary, departing midrib at 65 – 70° inconspicuously similar to primary, reticulate veins obscure, intra-marginal vein poorly visible below, usually invisible above, 0.5 – 0.8 cm from margins
    Inflorescences
    Inflorescences: erect to pendent after anthesis, much shorter than the leaves; peduncle 6 – 18 cm long, 0.3 – 0.5 cm diam., much shorter than the petioles, dark matt green, minutely speckled with pale green; spathe erect to spreading, coriaceous, broadly elliptic, dark to medium green outside, concolorous or slightly glaucous inside, densely white speckled in both surfaces in fresh material, 4 – 9 cm long, 2.5 – 4.3 cm wide, broadest at the base, inserted at 40 – 45° angle on the peduncle, rostrate at apex, obtuse at base, spathe margins meeting at 35 – 42°; spadix greyish-green, tapered, 4.5 – 7.6 cm long, 1 – 1.2 cm diam- at base, 5 – 9 mm diam- at apex, broadest near base; flowers rhomboidal to 4 lobed, 2 – 3 mm in both directions, the sides slightly sigmoid; 8 – 9 flowers visible in principal spiral, 11 – 13 flowers visible in alternate spiral; tepals matt; lateral tepals 1 – 1.1 mm wide, inner margins slightly convex, the outer margins 2-sided; pistils emergent, cylindrical to barrel-shaped, slightly glossy on exposed portion; stigma elliptic to discoid; stamens not covering the stigma; filaments not exerted, translucent, 2 – 2.5 × 0.5 – 0.6 mm; anthers whitish yellow, 0.5 – 0.6 × 0.6 – 0.7 mm, thecae ovoid, 0.5 – 0.6 × 0.3 – 0.4 mm
    Infructescences
    Infructescence with persistent spadix, spadix not bearing berries on the apical third; berries green, 3 × 3 mm
    Distribution
    Anthurium macropodum is so far known only from the type locality.
    Ecology
    Anthurium macropodum grows on forest floors 700 – 900 m above sea level in Espirito Santo state.
    Conservation
    This new species can be considered ‘vulnerable’ based on IUCN (2010) criteria because its only known area of occurrence is less than 20 km2.
    Note
    Anthurium macropodum is considered to belong to the section Urospadix, which is probably a basal lineage in the genus because of its strongly plesiomorphic aspects such as short internodes, cataphylls usually decomposed in fibres and the tendency to have leaves linear to elliptic. The subsectional position of Anthurium macropodum is uncertain, mainly considering that the Englerian taxonomy (broadly used currently) is strongly artificial (Temponi, pers. comm.). This species can be included in the complex that also contains Anthurium coriaceum (Graham) G. Don, A. viridispathum E. G. Gonç., A. molle E. G. Gonç. & J. G. Jardim, A. ensifolium Bogner & E. G. Gonç., A. erskinei Mayo and A. xanthophylloides G. M. Barroso (Gonçalves 2005; Gonçalves & Salviani2001; Gonçalves & Jardim 2009). This new species seems to be closer to Anthurium cleistanthum G. M. Barroso but differs in having the petioles much longer (16.5 – 59 cm as opposed to 11 – 12 cm) and the stem truly rhizomatous (instead of erect in A. cleistanthum). The epithet alludes to the Greek words makros (big) and podos (foot), because of the uncommonly long petioles.
