Stenospermation angosturense Engl.

• Genus: Stenospermation
• Botanical Background: The species was first described by George August Engelmann in the 19th century. The genus itself has been an important subject of study for botanists researching tropical plant ecosystems.

• Geographical Range: Native to the tropical regions of Colombia and Ecuador
• Environment: Naturally thrives in humid, shaded environments with well-drained soils; prefers areas with high rainfall and temperatures ranging from 20°C to 30°C.

Leaves

• Large, glossy, and heart-shaped with pronounced venation
• Dark green coloration contrasts with the pale undersides

Inflorescence (Spadix & Spathe)

• Large spathe, typically white or pale green
• Produces a faint, sweet fragrance
• Relies on insect pollination.

Growth Habit

• Terrestrial species
• Does not climb but forms dense clusters in its native habitat

Light Requirements

• Does best in bright, indirect light

Watering & Humidity

• Regular watering is essential to keep the soil consistently moist but not waterlogged
• Thrives in high humidity levels and should be placed in an environment with at least 60% humidity

Soil & Potting Mix

• A well-draining, moisture-retentive soil mix is recommended, such as one containing peat, perlite, and orchid bark

Temperature & Fertilizer

• Maintain temperatures between 20°C and 28°C for optimal growth
• Balanced, liquid fertilizer can be applied monthly during the growing season

Division

• Division of the rhizomes

Stem Cuttings (if applicable)

• Can be taken from healthy growth tips but must be kept in high humidity to root successfully

Seeds

• Seed propagation is possible, it is less commonly practiced due to the difficulty in obtaining viable seeds and the slow germination process

Typical Issues

• Aphids, mealybugs, and spider mites, which can be controlled through regular inspection and proper care
• Root rot is a concern if the soil retains too much moisture
  

Treatment Recommendations

• Insecticidal soap or neem oil for pest control
• Reduce watering frequency and allow the soil to dry out between waterings.

• Low-growing understory plant, contributing to the dense foliage

• Ability to thrive in humid, tropical environments also makes it ideal for indoor cultivation in tropical climates
• Striking foliage and unique inflorescence make this species highly prized by Aroid enthusiasts

Wild Population Status

• No significant conservation concerns reported for this species at present, though habitat destruction in some areas could affect its population in the wild

Market Availability

• Not as widely available as other Aroids, but it is sought after by collectors
• May be found in specialty nurseries or through plant exchange groups
