Araceae
Anthurium brent-berlinii Croat
SUMMARY
Epiphytic; internodes short, drying 2-3 cm diam.; cataphylls up to 14 cm long, at least 1-ribbed, possibly weakly 2-ribbed, drying reddish brown, lanceolate or oblong, persisting only at upper internodes as a large reticulum of coarse reddish brown fibers (with some longitudinal fibers), eventually deciduous, acute to weakly acuminate at apex. LEAVES: Petioles 70-85 cm long, drying 0.5-1.3 cm diam., prominently sulcate near base, drying pale grayish brown sometimes tinged with red; geniculum shaped like petiole, concolorous or slightly darker, 1.5-3 cm long, drying 5-6 mm diam.; blades usually cordate, sometimes weakly subhastate, obpyriform, somewhat abruptly acuminate (acumen 1.5- 2 cm long), 63-67 × 48-56 cm, ca. 1.1-1.3 times longer than wide, drying gray-green above and gray-brown faintly tinged with red below; anterior lobe 48-50 × 20-22 cm at midpoint; posterior lobes 24.5-26.5 × 14.5- 18 cm at midpoint; sinus parabolic, 15-20 cm deep, 9.5-11 cm wide at midpoint; midrib thicker than broad, concolorous to gray-brown above, narrowly rounded, sometimes drying with a rib, concolorous to slightly paler below; primary lateral veins 7-10 per side, 2.5-6.5 cm apart, departing midrib at a 55°-70° angle, straight or slightly arching towards collective vein, concolorous, somewhat prominent; lesser veins usually faint to obscure; basal veins 6-8 per side, 1st and 2nd free to the base, 5th and 6th coalesced to 4.5-5.5 cm, concolorous or slightly paler than surface, raised; posterior rib naked for 5.5-6.5 cm along sinus; collective veins faint, arising from 1st basal vein, much less prominent than primary lateral veins, 3-11 mm from margin. INFLORESCENCE with peduncle 39-48 cm long, drying 3-10 mm diam., drying grayish to reddish gray; spathe erect to erect-spreading, light green, lanceolate to oblong, 9.5-19.5 × 2-2.8 cm, acuminate at apex, spadix orange, slightly tapered to apex, slightly stipitate (stipe 4-10 mm long), pendent, 23 cm long, drying 8 cm diam. Flowers 2.8-3 × 2.6-2.8 mm, 7 to 8 visible per spiral; lateral tepals 1.5 mm wide, 2-sided. INFRUCTESCENCE to 56 cm long, drying to 1.4 cm diam.; berries white.
