Araceae
Anthurium andicola Liebm.
SUMMARY
Epiphytic or on rocks, sometimes in soil on rocky cliffs; stems less than 20 cm long; leaf scars ca. 1.7 cm wide; roots thick, descending; cataphylls subcoriaceous, 2-4.5 cm long, tinged red at margins and apex, the apex round, minutely apiculate, drying medium brown (B & K Yellow 5/5), weathering to fibrous network at base. LEAVES with petioles erect to spreading, 18-47 cm long, 4-8 mm diam., sharply sulcate, weakly glaucous; geniculum 1.5-2 cm long, faintly tinged red; blades broadly ovate-deltoid, thick, narrowly acuminate at apex (rarely rounded), usually prominently lobed at base (rarely merely obtuse), 20-37.5 cm long, 13-27 cm wide, broadest at point of petiole attachment; anterior lobe 19-29 cm long, the margins broadly rounded; posterior lobes 7.5-13 cm long; sinus arcuate with de-current petiole to parabolic to sometimes hippocrepiform; both surfaces matte to semiglossy, the lower surface weakly glaucous; midrib convexly raised above, diminished and flat at apex, more acutely raised below; basal veins 3-6 pairs, the first free to base, those remaining coalesced 1-3 cm, posterior rib naked, weakly curved, the outer margin scarcely turned up; primary lateral veins 3-5 per side, departing midrib at 55° angle, ± straight to collective vein, sunken above, raised below, interprimary veins sunken above, raised below, tertiary vein prominulous above, obscure below (drying prominent on both surfaces); collective vein arising from the first basal vein or from one of the lowermost primary lateral veins, sunken above, raised below, 4-8 mm from margin, sometimes the second basal vein running almost to apex. INFLORESCENCE erect, shorter than or equal to leaves; peduncle 16-40 cm long, 4-6 mm diam., terete, sometimes with a single ridge tinged reddish; spathe thin, medium green (B & K Yellow-green 5/5), narrowly ovate to ovate-lanceolate, 5.5-7.5 cm long, 2-2.8 cm wide, narrowly acuminate at apex, rounded to subcordate at base, inserted at 45° angle on peduncle; spadix green heavily tinged purple or dark purple (B & K Blue-purple 2/10), 4-10.5 cm long, 5-9 mm diam. at base, 2-5 mm diam. at apex; flowers square 3-3.6 mm in both directions, the sides straight parallel to spirals, weakly to jaggedly sigmoid perpendicular to spirals; 5-6 flowers visible in the principal spiral, 6-7 flowers visible in the alternate spiral; tepals matte, weakly punctate, very minutely papillate, the lateral tepals 2.1-2.2 mm wide, the inner margin broadly rounded; pistils weakly emergent, green to purplish (paler than tepals); stigma linear, ca. 7 mm long, with large, clear droplets ca. 1 month before stamens emerge; lateral stamens emerging from the base, followed by alternates in rapid progression, leading stamens preceding the next in the series by 2 or 3 spirals; anthers white to pale yellow, ca. 0.7 mm long, 0.8 mm wide, held over pistil then retracting and held at sides of pistil; thecae ellipsoid, somewhat divaricate; pollen yellow, fading to white. INFRUCTESCENCE pendent, spathe deciduous; berries orange, obovoid, rounded at apex, 1.5 cm long, 8 mm diam., 6 mm thick; mesocarp fleshy, orange; seeds 2, greenish orange, flattened, ca. 9 mm long, 5 mm wide.
