Robust to massive herb, terrestrial or nomadic vine, appressed-climbing habit. SEEDLINGS: bearing foliage leaves. JUVENILE PLANTS: root climbers; stems brown to grayish, smooth or warty, cylindrical; internodes 7–12 cm long, 1–2 cm diam.; petiole distinct, dark green, smooth, 14–17 cm long, sheathed up to half their length; petiole sheath semi-deciduous; blades ovate to lanceolate, cordate at base, acuminate, coriaceous, 15–23 × 14–20 cm, not appressed to the phorophyte; fenestrations absent.

INFLORESCENCES on ascending stems, 2–5 simultaneously at flowering time, arranged in the leaf axils or into cataphylls; peduncle 12–25 cm long, 2.5–3.0 cm diam., tuberculate; spathe short acuminate, bluish-green during development, yellowish externally and cream internally with revolute margins and closed (at apex) at anthesis, deciduous after anthesis, 12–23 × 7–13 cm, up to 5 cm longer than the spadix; spadix creamy-yellowish (both during development and at anthesis), 10–20 cm long, 2.5–3.0 cm diam., 3.4–5.8 times longer than wide; basal sterile flowers with a yellow stigmatic secretion, 5–8 mm long; fertile flowers 7–10 mm long; stamens 1.2–9.5 mm long, with laminar filaments; anthers 2.0– 2.7 mm long; ovary quadrangular in longitudinal section, ribbed, 5–8 × 5–7 mm; style compressed and hexagonal, 2.5–3.0 × 4–7 mm; stigmatophore slightly cupuliform, 0.3–0.4 mm long; stigma circular and sunken, with transparent secretion; berries with a light green stylar cap during development, mature stylar cap yellowish; pulp white; seeds dark green, 5–10 mm long.
Distribution and ecology: — Monstera deliciosa is known in Southern Mexico (Chiapas, Oaxaca, Tabasco, and Veracruz) and Guatemala, at elevations of 90–2750 m, in Premontane rain forest, Tropical moist forest and Tropical wet forest life zones.
Phenology: —Flowering March, April, and May. Fruit is present all year.
Discussion: —The species is a member of sect. Tornelia and is distinguished by its smooth stem with short internodes, petioles shorter than the blades, ovate cordate, moderately coriaceous leaves with conspicuous secondary veins, peduncles about as long as spadix and the spadix which becomes blackish to bluish green.
Monstera deliciosa was considered a widely distributed species in Central America. However, through fieldwork in Costa Rica and Panama this species is found only in cultivated form. The natural populations that were considered for Costa Rica and Panama with hanging habit and not robust plants have been considered as Monstera tacanaensis Matuda. This species was established as a synonym by Madison in 1997, but Cedeño-Fonseca et al. (2020c) have considered that these individuals belong to a different species and are not part of the M. deliciosa variation. To corroborate this, Cedeño-Fonseca et al. (2020c) carried out fieldwork in the type locality of M. tacanaensis in the Volcán Tacaná region
Mexico and Guatemala are the only regions where M. deliciosa has been collected naturally. The other collections in Central Amerca indicate that they are collections of cultivated plants. Monstera deliciosa is a species that is distributed in different habits in Mexico, dry forests, humid forests and cloud forests, possibly being the species with the greatest diversity of growth habitats.
