About the plant

Monstera acacoyaguensis is a flowering plant in the family Araceae and the genus Monstera, section Monstera. its native range is Mexico (Chiapas) to Belize, at altitudes below 200 meters. As an adult, it grows as an epiphyte. Juvenile plants grow as terrestrial creepers, and undergo dramatic morphogenesis upon reaching a suitable climbing surface. Adult plants have green, smooth petioles 40-65 centimeters long, with adaxially glossy, leathery, ovate leaf blades that rapidly truncate to the petiole, 60-85 centimeters long and 35-45 centimeters wide. Its fenestrations are numerous, ovate, and mostly originate mid-rib, sometimes in two to three rows. These perforations curl adaxially, and are 2-5 centimeters wide and 4-12 centimeters long. Monstera acacoyaguensis has a light yellow to cream-colored spathe, 25-30 centimeters wide and 25-35 centimeters tall. Its spadix is yellow and cylindric, 1.5-2 centimeters wide and 18-22 centimeters long. Its seeds have not been described. It has been described as having an unusually persistent spathe, lasting up to 20 days at maturity in comparison to other monstera, who only flower for two to three days. M. acacoyaguensis is also notable because, unlike most other monstera, it naturally grows in conditions of full sunlight.

What this does not cover

The figures above are what published sources say, not measurements of the plant in your room. They say nothing about your pot size, your water, the season, or how far from the glass the plant stands, and those decide more than any figure here does.

Humidity has no species figure because no source read for this site publishes one, and the only temperature published for this plant is a cold floor. The simulator fills those gaps with general figures for its kind of plant, marked as general and listed on how we read sources. Where a toxicity row says the plant was not assessed, that is the absence of a finding and not a finding of safety.

If something is already wrong, the diagnosis tool asks about the soil, the window and the watering, which is where the answer usually is.
