Monstera obliqua 'Pastaza Form'
Pastaza Form Monstera
Monstera obliqua Miq. Morphology
About Monstera obliqua Miq.
The Monstera obliqua 'Pastaza Form' is an epiphyte native to the humid premontane rainforests of the Pastaza province in Ecuador. It is distinguished by slender, elongated, oblong leaves with moderate fenestration patterns and a drooping habit. It thrives in environments with high humidity and stable, warm temperatures, typically ascending trees in its natural habitat. Its foliage shape and fenestration pattern distinguish it from other locality forms of the species.

Before You Buy
Shared checklist for Monstera obliqua and its cultivated forms
- Genuine Monstera obliqua leaves are extremely fenestrated (70-90% hole coverage) and paper-thin/near-translucent — thicker, less extreme fenestration is almost always Monstera adansonii
- Look for leafless exploratory stolons on the plant or cutting — true obliqua produces these before leaves; adansonii does not
- Ask the seller for the specific locality/collection origin — reputable true-obliqua sellers can usually name it, generic 'obliqua' listings with no origin are a red flag
- Given the price and rarity involved, request close-up photos of an actual leaf held up to light before buying, not just a listing photo
Propagation Guide
How to Propagate Monstera obliqua Miq.
Shared across every form of Monstera obliqua — see this form's own Morphology for variegation-specific propagation notes.
6-12+ months
Cultivar character is preserved through vegetative cuttings
Notoriously difficult and slow to propagate — single-node cuttings are the norm given how rare source material is, and rot rather than rooting is the most common outcome without near-sterile, high-humidity propagation conditions (sphagnum in a sealed box or in-vitro tissue culture).
Care Guide
Monstera obliqua Miq. Care Guide & Growing Conditions
General care shared across all forms of Monstera obliqua — cultivated forms may need brighter light or higher humidity than the plain species; check this form's Quick Facts above.
Very open, chunky epiphytic mix: sphagnum moss, fine orchid bark and perlite — true obliqua roots are fine and easily suffocated or rotted in dense substrate.
Keep consistently and lightly moist — the paper-thin leaves have almost no water storage capacity and desiccate quickly, but waterlogged roots rot just as fast.
75-95% is non-negotiable. This species is essentially impossible to grow well outside a closed, humidity-controlled enclosure or greenhouse in a UK home.
Very dilute liquid fertiliser (quarter strength or less) no more than once a month — this is an extremely slow-growing plant with minimal nutrient demand.
Rarely — disturb the root system as little as possible; repot only when the container is genuinely outgrown.
Common Problems
Leaf desiccation / crisping
Humidity below the 75%+ this species requires
Move into a sealed cabinet or greenhouse — open-room humidifiers are rarely sufficient for true obliqua
Stem/node rot
Overwatering combined with dense substrate or poor airflow
Repot into a very open mix, improve airflow, and reduce watering frequency while keeping ambient humidity high
Mislabelled purchase
The overwhelming majority of plants sold as 'Monstera obliqua' are actually Monstera adansonii
Verify fenestration ratio (70-90% hole coverage), leaf translucency, and presence of leafless exploratory stolons before paying true-obliqua prices
Pastaza Basin Collection
A locality form of Monstera obliqua from the Pastaza Basin — the river system that drains Ecuador's eastern Amazon region into Peru. Ultra rare, top price tier. Pastaza material overlaps geographically with some of the most intensively collected South American Monstera populations. If this is authentic obliqua with a genuine Pastaza provenance, it is precisely the kind of locality-tracked material that gives collector collections scientific legitimacy beyond the aesthetic. The fenestration-to-blade ratio is the test: more hole than leaf means obliqua.
Also in: Fenestrated Grails
The M. obliqua complex — leaves dominated by fenestration rather than solid tissue, the most extreme expression of leaf-splitting in the genus.
