Type: — Novae Andalusiae [ VENEZUELA. Sucre or Monagas], prope Cocollar et coenobium Caripense [near Cocollar (Sucre) and Caripe monastery (Monagas)], alt. 400 hex. [≡ fathoms, i.e. ca. 730 m], [1799], A. von Humboldt & A. Bonpland s.n. (lectotype P-P00679587!, designated by Cedeño-Fonseca et al. (2022)) .
Robust nomadic vine, with appressed-climbing habit at first, then sometimes with the mature shoots free and pendent. SEEDLINGS: filiform. JUVENILE PLANTS: root climbers; stems light brown or beige, warty, dorsoventrally compressed; internodes 3–5 cm long, 5–8 mm diam.; petiole inconspicuous, dark green, smooth, 6–10 mm long; blades obovate, cordate at base, acuminate, coriaceous, 10–18 × 6–10 cm, sometimes variegated, completely appressed to the phorophyte; fenestrations absent. ADULT PLANTS: root climbers; stems yellowish or beige, with abundant pustules that generate a warty surface, cylindrical or dorsoventrally compressed; internodes 2–6 cm long, 1.0– 3.5 cm diam., 1.7–2.0 times longer than wide; cataphylls slightly deciduous; anchor roots light brown; feeder roots beige, warty; petiole light green, white-dotted, striated and pustulate at base, warty, 30–55 cm long, fully sheathed or up to 3 cm long; petiole sheath deciduous; geniculum smooth, slightly terete, 2–5 cm long; blades ovate to elliptic or oblong, widely cuneate to rounded or truncate at base, sometimes peltate, obtuse to long-acuminate at apex, subcoriaceous or chartaceous, drying greenish-gray, brownish or yellowish, 55–100 × 30–35 cm, 1.6–2.1 times longer than wide, not decurrent on the geniculum; midrib flattened adaxially, convex abaxially, drying yellowish or dark brown on both surfaces; primary lateral veins 12–25 per side, decurrent on the midrib, bifurcated in the medial part of its length, obscure adaxially, prominent abaxially, departing midrib at 65–75°, drying black or dark brown; secondary veins reticulate and prominent; collective veins not visible; fenestrations absent or present; margins entire to pinnatilobed, with 3–6 lobes per side, 1.5–2.5 cm wide where the middle lobes are narrow. INFLORESCENCES on ascending and pendent stems, 1–7 simultaneously at flowering time, subtended by cataphylls which sometimes leave dry fragments on the peduncles; peduncle smooth, light green with white dots, 5–10 cm long, 0.7–1.2 cm diam.; spathe apically short-acuminate or obtuse, light green during development, pink externally and cream internally at anthesis, coriaceous, completely open at apex, deciduous after anthesis, 8–16 × 7–13 cm, up to 1 cm longer than the spadix; spadix white during development, creamy yellow at anthesis, 7–15 cm long, 1.5–3.5 cm diam., 1.5–2.0 times longer than wide; basal sterile flowers 3–5 mm long, narrow towards base; fertile flowers 4–8 mm long; stamens 1–7 mm long, with laminar filaments; anthers 3–4 mm long; ovary flattened, rectangular in longitudinal section, ribbed, 4–5 × 2–4 mm; style 2–3 × 4–5 mm, compressed and hexagonal; stigmatophore slightly conical, 0.3–0.5 mm long; stigma circular, with a yellowish stigmatic secretion; berries with a yellowish green stylar cap during development, mature stylar cap beige-cream; pulp white; seeds dark brown with white dots, spherical or oblong, 5–7 mm long.
Distribution and ecology: —From Mexico to Bolivia, Venezuela, French Guiana, Brazil, Trinidad & Tobago, at elevations of 0–450 in Tropical moist forest and Tropical wet forest life zones; in primary and secondary forest, and open areas.
Phenology: —Flowering registered in January, May, and April. Fruiting in January and April.
Discussion: —The species is a member of sect. Marcgraviopsis . It differs from the other species by its smooth and mottled petiole with warts on the base, the deciduous petiolar sheath, the subterete geniculum, the entire or fenestrate leaf blade with the base cordate and sometimes peltate, the primary lateral veins bifurcated at about half their length, inflorescences subtended by deciduous cataphylls in a sympodial series between episodes of monopodial leafy growth, the externally pink spathe and slender flowers with circular stigmas.
Monstera dubia is similar to M. punctulata , but the latter has the spathes pale green externally, the petioles verrucate and grooved throughout their length, the leaf blade usually with numerous conspicuous fenestrations between primary lateral veins and grows at elevations above 600 m, while M. dubia generally has a less conspicuously fenestrate leaf and grows in the lowlands of the Pacific slope.
