Anthurium huacamayoense Croat

Epiphytic; cataphylls 8 cm long, persisting at upper nodes as fibers with fragments of epidermis intact. LEAVES with petiole 41 cm long, 2-4 mm diam., becoming narrower towards blade, concolorous, terete, broader than thick, narrowly to broadly V-sulcate both adaxially and abaxially; blades trisect with medial lobe markedly longer and slightly narrower than lateral lobes, 36 cm long, 16 cm wide, 2.3 times longer than wide, .9-1.3 times as long as petiole, matte-subvelvety above, weakly glossy below; medial lobe lanceolate, acuminate at apex, obtuse at base, 36 cm long, 5 cm wide; lateral lobes lanceolate, falcate, acuminate at apex, obtuse at base, unequal in length (right lateral lobe 28.5 cm long, left lateral lobe 26 cm long), more or less equal in width, 6 cm wide; midrib weakly to deeply sunken above, acutely raised below; primary lateral veins on medial and lateral segments scarcely apparent and quite numerous above, acutely raised below, extending to margin at almost a 90° angle, with the notable exception of one of lower primary veins on lateral segments only which extends obliquely to margin from midrib at 6 cm from base and is weakly to deeply sunken above and acutely raised below, closely resembling midrib; tertiary veins numerous, in part raised and concolorous on both surfaces. INFLORESCENCE. Peduncle 16.5 cm long, 1-2 mm diam., flattened, weakly and broadly sulcate; spathe 6 cm long, 9-11 mm wide, green; spadix green, 9 cm long, 4 mm wide, scarcely tapered to apex, bluntly rounded at apex. Flowers 6-7 visible per spiral, 4.3-4.5 mm long, 3.0-3.5 mm wide, dark brown and densely granular; lateral tepals 2.8-3.2, outer margin 2-sided to broadly rounded, inner margin rounded to broadly rounded.
