Anthurium interruptum Sodiro,

Anales Univ. Centr. Ecuador 15: 301. 1902. TYPE: Ecuador. Growing in the W slopes of the Cordillera de Angamarca, Nov. 1899, Sodiro s.n. (B, holotype).

Anthurium radicosum Standl. & Steyerm., Publ. Field Mus. Nat. Hist., Bot. Ser. 23: 210. 1947. TYPE: Guatemala. Alta Verapaz: along Río Icvolay, 300-350 m, 6 Mar. 1942, Steyermark 44776 (F, holotype).

Scandent epiphyte; stems elongate, 8-33 cm long; cataphylls drying brown, weathering and ultimately deciduous; petioles more or less terete, 1.8-13 cm long; blades lanceolate to elliptic, oblong-elliptic or oblanceolate, subcoriaceous, 5-21 cm long, 2.2-9.5 cm wide. Inflorescence erect-spreading; peduncle 4.5-14 cm long; spathe green, oblong-lanceolate, 3.7-5 cm long, 1-1.5 cm wide; spadix green, becoming brownish purple; berries red, broadly obovoid, ca. 7 mm long, flattened at apex with central depression. See Croat (1983: 307) for a more complete description.

The species is known from Guatemala to Panama, Ecuador, and surely also on the Pacific slope of Colombia. In Costa Rica and Panama it is known from premontane wet, tropical wet, premontane rain, and lower montane rain forest at elevations from 150 to 1,000 m. In Panama it is known from both the Atlantic and Pacific slopes.

Anthurium interruptum is provisionally placed in section Xialophyllium and can be recognized by its scandent stem with greatly elongated internodes alternating with two or more successive abbreviated internodes giving the appearance of several leaves being clustered at a node. In addition, no other scandent, entire-leaved species is known to have bright red berries.
