    Anthurium acutibacca is known only from Choco Department of Colombia in the Cabo Corrientes region in Tropical moist forest (bh-T) where it is sparse to moderately common, almost always found growing on trees at 1.5-15 m above the ground, but occasionally found on rocks.

    General Description

    Epiphyte or epipetric, stems with conspicuous indented petiole scars, 7-10 cm long, 0.9-3 em diam.; internodes very short (1-3 mm), very light reddish to medium green, semiglossy, covered with a dense mass of greenish roots; cataphylls 3-13 cm long, semiglossy, obtusely 1-ribbed, becoming bluntly acute toward apex, persisting semi-intact as a reticulum of mostly longitudinal fibers, retained at upper nodes then deciduous. LEAVES spreading; petioles (9)17-46 cm long, 4-6 x 5-8 mm, subterete or U-shaped in cross-section, thicker than broad and narrow and obtusely sulcate adaxially (some-times broadly and obtusely sulcate with obtuse margins, these more acute toward the apex), medium green, pale-speckled or dark short-lineate, semiglossy to matte; geniculum 1.1-3.2 cm long, yellow-green, sometimes tinged with red, sulcate like the petiole; blades elliptic-Ianceolate to narrowly elliptic, gradually and weakly acuminate at apex, acute to weakly attenuate at base, 31-58 x 6.5-13 cm, broadest at or above the middle, subcoriaceous, dark green and weakly glossy to semiglossy above, paler and purplish brown glandular-punctate below, weakly glossy to matte below (in juvenile leaves the blade is glossy above), drying greenish to yellow-green; midrib narrowly rounded on both surfaces (in broad valley above), ca. 2 mm wide at base and slightly paler than surface to concolorous above, moderately to conspicuously paler below; primary lateral veins 5-13 pairs, departing midrib at 30-40°(-58°) angle, straight to weakly arcuate, etched-sunken and concolorous above, weakly raised and concolorous below; collective vein prominently raised below, 5-15 mm from margin, weakly loop-connecting primary lateral veins; minor veins obscure. INFLORESCENCE spreading to erect-spreading; peduncle terete, 26-63 cm long, 4-6 mm diam., ca. 2 times longer than petioles, green to pinkish, pale-speckled to pale-lineate; spathe 5-7 cm long, 7-10 mm wide, cuspidate at apex, spreading at anthesis and slightly twisted, with margins prominently rolled under, subcoriaceous at anthesis, pale green, semiglossy outside, matte inside, deciduous; stipe 3.5-3.8 cm long in front and 2-2.2 cm in back, semiglossy, medium green; spadix erect, more or less cylindrical, weakly tapered to apex, 6-7.5 cm long, (0.7)1-1.2 cm diam. at base, 6-8 mm at 1 cm from apex, bluntly rounded at apex, dull medium pink to lavender; flowers 2 x 3 mm, ca. 7 visible in the principal spiral, with glossy tepals. INFRUCTESCENCE pendent; spadix 11.5-15 cm long, 2-2.5 cm diam., tepals dark brown; berries ellipsoid, with a narrow conical beak at apex, 9 mm long (including the beak that is 3 mm long), 4 mm diam., bright red, translucent, with seeds visible; seeds 2.
