Heteropsis steyermarkii G.S.Bunting

• Genus: Heteropsis
• Botanical Background: First described by G.S. Bunting, Heteropsis steyermarkii has since drawn attention for its unique features. Its discovery contributed to the broader understanding of aroid diversity in tropical ecosystems.

• Geographical Range: Native to select tropical regions in the Americas. Its distribution appears to be limited, highlighting its status as a species with a relatively restricted natural range.
• Environment: Thrives in humid, shaded understories of tropical forests with well-draining, organic-rich soils. It favors consistently warm conditions and high humidity, which are typical of its native habitat.

Leaves

• Large, ovate to heart-shaped leaves
• Glossy texture and subtle venation
• Deep green coloration with lighter veining

Inflorescence (Spadix & Spathe)

• Slender spadix enclosed by a broad spathe
• Spathe is generally green with hints of cream
• Produces a delicate scent

Growth Habit

• Terrestrial species
• Clumping growth form
• Robust rhizome that supports multiple stems

Light Requirements

• Bright, indirect light

Watering & Humidity

• Regular watering
• Evenly moist yet well-drained soil
• High humidity levels

Soil & Potting Mix

• A loose, organic-rich potting mix enhanced with perlite or orchid bark
• Container that allows for ample airflow around the root

Temperature & Fertilizer

• Temperatures range from 65 to 80°F
• A balanced liquid fertilizer applied during the growing season

Division and Cutting

• Rhizomes division
• Division should include a portion of the root system

Seeds

• Less common due to the species’ slow and sometimes unpredictable germination
• Maintain consistent moisture and temperature

Typical Issues

• Spider mites and mealybugs
• Root rot

Treatment Recommendations

• Regular monitoring and proper sanitation
• Insecticidal soap or neem oil
• Adjust in water practices

• Named in honor of the botanist Steyermark
• Rare and distinctive appearance

• Supports specialized pollinators in its native ecosystem

Wild Population Status

• Limited distribution
• Concern over habitat loss and environmental changes

Market Availability

• Found through specialized growers
• Relatively rare in the horticultural trade
• Sought after by dedicated collectors
