Stenospermation densiovulatum Engl.

• Genus: Stenospermation
• Botanical Background: The species was first described by the botanist George Engler in the late 19th century, contributing to the understanding of the genus Stenospermation within the Araceae family.

• Geographical Range: Native to the humid tropical forests of South America, primarily found in Colombia and Ecuador,
• Environment: Prefers environments with high humidity, warm temperatures, and well-draining, slightly acidic soils; typically found in lowland tropical rainforests where rainfall is consistent year-round

Leaves

• Large, glossy, and lance-shaped, typically measuring up to 50 cm in length
• Deep green color with slight variations in texture

Inflorescence (Spadix & Spathe)

• Consists of a dark, elongated spadix surrounded by a pale, tubular spathe
• Spadix may emit a faint, sweet scent to attract pollinators like flies and beetles.

Growth Habit

• Typically terrestrial, growing from a rhizome
• Does not climb but may form dense clusters as it matures.

Light Requirements

• Optimal light is bright, indirect sunlight
• Direct sunlight can scorch the leaves, so a location with filtered light or partial shade is ideal.

Watering & Humidity

• Keep the soil consistently moist but not waterlogged
• Thrives in high humidity
• Misting or placing a humidity tray beneath the pot can help replicate its native conditions.

Soil & Potting Mix

• A well-draining, airy potting mix is recommended

Temperature & Fertilizer

• Temperature range of 22-28°C (72-82°F)
• Fertilize monthly during the growing season with a balanced liquid fertilizer, diluted to half-strength.

Division

• Most common propagation method is through division of the rhizome

Stem Cuttings (if applicable)

• No established cutting method

Seeds

• Propagation by seeds is possible, but it requires the seeds to be fresh. Germination is slow and best attempted in a warm, humid environment.

Typical Issues

• Spider mites, mealybugs, and aphids
• Root rot can occur if the plant is overwatered

Treatment Recommendations

• Use insecticidal soap or neem oil for pest control
• For root rot, ensure the plant is not sitting in waterlogged soil and provide good drainage.

• While not widely known outside of botanical circles it  plays an important ecological role in its native habitat, where it contributes to the undergrowth's biodiversity

• Enthusiasts prize this species for its attractive foliage and unique spadix and spathe structure
• Rare addition to any collection, especially for those interested in aroids.

Wild Population Status

• No immediate conservation concerns, though habitat loss in some regions could pose a long-term threat to the species.

Market Availability

• Relatively rare in the horticultural market
• Mostly available through specialty nurseries or botanical gardens.
