Spathiphyllum uspanapaense Matuda

• Genus: Spathiphyllum
• Botanical Background: Described by Matuda, this species has been studied for its distinctive morphology and adaptation to shaded, humid environments. Its taxonomic placement is supported by both traditional morphological methods and modern molecular data.

• Geographical Range: Native to tropical rainforests in parts of Central America
• Environment: Thrives in warm, humid conditions with consistently moist, well-draining soils. The species typically grows in the shaded understory where filtered light and high ambient humidity are prevalent, mimicking its natural habitat.

Leaves

• Glossy, dark green, and ovate to lanceolate, with a smooth texture and prominent venation that enhances their visual appeal

Inflorescence (Spadix & Spathe)

• Produces a slender spadix surrounded by an elegant white spathe, usually measuring around 8–10 cm in length
• The spathe may emit a mild fragrance to attract insect pollinators

Growth Habit

• Terrestrial plant that grows from a rhizome, forming a compact rosette of leaves. Its non-climbing, moderate habit makes it well-suited for container cultivation

Light Requirements

• Provide bright, indirect light to promote healthy growth and flowering
• Direct sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Keep the soil evenly moist while ensuring proper drainage to prevent waterlogging and root rot
• High humidity is crucial
• Regular misting or the use of a humidity tray is recommended

Soil & Potting Mix

• A well-draining, organic potting mix, such as a blend of peat, perlite, and bark, is ideal to replicate its native rainforest soil conditions

Temperature & Fertilizer

• Ideal temperatures range from 22°C to 28°C (72°F to 82°F)
• During the growing season, feed with a balanced, diluted liquid fertilizer every 4–6 weeks
• Reducing the amount during winter

Division

• Propagation is most effectively achieved by dividing the rhizomes during repotting
• Each division should include healthy roots and at least one shoot to ensure successful establishment

Seeds

• Propagation is possible, although it is less common due to variable germination rates and a longer maturation period compared to vegetative propagation

Typical Issues

• Spider mites, mealybugs, and aphids
• Overwatering may lead to root rot, and poor air circulation can promote fungal infections

Treatment Recommendations

• Treat pest infestations with insecticidal soap or neem oil
• Adjust watering practices and improve air circulation to prevent issues like root rot and fungal infections

• Admired for its air-purifying properties, effectively removing indoor toxins such as formaldehyde and benzene
• Glossy foliage and refined spathe also make it an attractive subject in botanical research

• Enthusiasts prize this species for its elegant, glossy leaves and delicate white spathe, which add a tropical touch to indoor spaces
• Its adaptability to low-light conditions and low maintenance requirements further enhance its appeal

Wild Population Status

• No immediate conservation concerns
• Habitat loss in tropical rainforests poses a potential long-term threat

Market Availability

• Moderately available through specialized nurseries and garden centers that focus on tropical houseplants, making it accessible to both novice and experienced collectors
