    General Description
    Planta epiphytica; caudex brevis; internodia brevia, 1-3.5 cm diam.; petiolus 53-104 cm longus, teres; lamina cordato-sagittata, 34-55 cm longa, 16-29 cm lata, coriacea; pedunculus 33-62 cm longus, 5-15 mm diam.; spatha pendens, 9.6-33.5 cm longa, 1.5-2.8 cm lata, viridis; stipes 2- 4 mm longus; spadix viridis, 15-33 cm longus, ad basim 6-12 cm diam. Epiphytic; stem short, drying dark yellowish brown; internodes short and 1-3.5 cm in diam. Cataphylls 14-25.3 cm long, acute at apex, coriaceous, drying grey-brown to brown, several persisting intact. Leaves with petioles semi-erect to erect, 53-104 cm long, 6-16mmin diam., terete, cylindrical, medium green, short pale-lineate, weakly glossy, usually drying dark brown; geniculum 3-5 cm long, drying darker than rest of petiole; blades cordate-sagittate, coriaceous, acuminate to caudate-acuminate at apex, 34-55 × 16-29 cm, 1.8-2.1 longer than wide, broadest at base, c. 1/2 as long as petiole; upper surface dark green, weakly glossy, drying grey-brown to brown; lower surface moderately paler, weakly glossy, drying brown to grey-green; anterior lobe 38-52 cm long; posterior lobes 10.5-15 × 19-28 cm, 1.5-1.6 longer than wide, held upward at 45° to midrib, usually directed inward or being flattened, narrowly rounded at apex; sinus hippocrepiform to obovate, 11-14.5 cm deep; major veins convex on both sides; midrib drying brown above, prominently raised, drying brown to reddish brown below; primary lateral veins in 4-5(-6) pairs, arising at 40-60°, straight at first, finally forming a broad curve before merging into collective vein; basal veins 3-7, 1st pair free to base, 2nd pair coalesced for 1.5-2 cm, most of the remainder coalesced for 2.7-5 cm; posterior rib naked, 3.5-5 cm, weakly curved; tertiary veins clearly visible below, weakly raised, in part darker than surface, prominently raised on drying; collective veins arising from 1st basal veins with a secondary collective vein arising from the 2nd basal vein and not as prominent as primary lateral veins, 1st collective veins 8-15 mm from margin. Inflorescence semi-erect to erect; peduncle 33-62 cm long, 5-15 mm in diam., 0.5-0.6 times as long as petiole, drying brown to dark brown; spathe pendent, 9.6-33.5 × 1.5-2.8 cm, inserted at 30-40°, 1/3 to 1/2 as long as peduncle; subcoriaceous to coriaceous, green, usually drying dark reddish brown, often withering after anthesis, stipe 2-4 mm long in rear; spadix long-tapered, semi-erect, 15-33 cm long, 4-6 mm wide at apex, 6-12 mm wide at base, 32-38 times longer than wide, green, becoming purple to purplish brown. Flowers 7-12 visible per spiral, square, 1.8-2.3 × 1.3-1.4 mm, tepals 1.8-1.9 mm wide, subtriangular, with inner margins broadly rounded; pistils barely visible; stigma 0.6 × 0.3 mm, raised, ellipsoid with oblong slit; stamens held at level of tepals, anthers 4 × 5- 5.5 mm, thecae ovoid-ellipsoid, moderately divergent. Infructescence with spadix 32-44 cm long, 2-3 cmwide; berries early emergent, green when young, turning yellowish, ultimately red-orange.
    Distribution
    Anthurium macdanielii occurs in Ecuador in Napo, Pastaza and Sucumbíos provinces, in Peru it occurs in Leoncio Prado and Alto Amazonas provinces,
    Diagnostic
    The species is distinguished by short, thick internodes, cataphylls persisting intact, narrowly cordate-sagittate blades with two or more basal veins extending all the way to the apex and prominulous tertiary veins, by the purplish long-tapered spadix, the green, spreading spathe and orange berries.
