Anthurium penae Croat
SUMMARY
Epiphytic; stems drying dark brown; leaf scars 5-6 mm × 1-1.5 cm; internodes short, drying 1-1.5 cm diam.; cataphylls 4.2-8.2 cm long, drying reddish brown, persisting at upper nodes as almost intact to pale linear fibers near apex, as a reticulum near base, eventually deciduous, acute to acuminate at apex. LEAVES: Petioles 4.5-18.5 cm long, drying 2-3 mm diam., sharply sulcate above, drying light green to brown-yellow; geniculum slightly thicker than petiole, darkened, 7-12 mm long, drying 3-4 mm diam.; blades +/- elliptic, obtuse to rounded or emarginate at apex, cuneate to slightly attenuate at base, 14-22 cm long, averaging 17.9 cm, 4.4-8.9 cm wide, averaging 6.2 cm, 2.5-3.1 times longer than broad, averaging 2.9 times longer, broadest at or slightly above middle, revolute at margins; upper surface drying yellowish green; lower surface brownish green, tinged with gray, glandular-punctate; midrib convex, sometimes flat, sometimes sunken above, drying ca. 0.5-1 mm diam., concolorous, narrowly convex below, drying 1-2 mm wide, concolorous; primary lateral veins 6-7 per side, about 1.2-2.2 cm apart where they arise from the midrib, arsing at a 30°-35° angle from the midrib, straight to the collective vein, concolorous, sometimes drying sunken with an irregular ridge along both margins, sometimes slightly raised above, slightly loop-connected above and below; interprimary veins almost as conspicuous as primary veins, usually one, sometimes two between each primary vein; collective veins arising from near base, concolorous, more prominent than primary veins, 5-11 mm from margin. INFLORESCENCE with peduncle 17.5-26 cm long, averaging 22.8 cm, drying 1-4 mm diam., reddish brown; spathe reflexed-spreading to reflexed, red or purple, sometimes tinged with green, oblong, 2.8-3.5 cm × 5-7 mm, held at a 155°- 180° angle on peduncle, acute or apiculate at apex; spadix purple or dark red, cylindrical, curved away from spathe, spreading to 45°- 90° angle, 7-14.5 cm x 5-9 mm. Flowers ca. 3 × 2 mm, 3-4 visible per spiral, lateral tepals 2 mm wide, margins 2-sided. INFRUCTESCENCES 8.6 cm long, drying 1.6 cm diam., setting berries in lower 1/2 to 3/4 of its length, berries pink.
