Masdevallia cerastes

This distinctive Ecuadorian species produces unique flowers with fused sepals forming a tubular structure and curved, horn-like sepaline tails that create an unusual and captivating appearance.

• Light: Bright shade to filtered light, avoiding direct sun which can burn the foliage; east-facing windows or 50-70% shade cloth recommended
• Temperature: Cool grower - 50-68°F (10-20°C) days, 45-55°F (7-13°C) nights; benefits from consistent cool conditions year-round with good day-night temperature differential
• Humidity: 70-85% with excellent air circulation to prevent fungal issues; use fans or natural airflow, mist in morning hours during dry periods
• Watering: Keep consistently moist year-round using pure water (rainwater or RO preferred), reduce frequency slightly in winter but never allow to dry completely; water in morning to allow foliage to dry before evening

Additional Notes

Native to the cloud forests, the species name 'cerastes' refers to the horn-like appearance of the curved sepaline tails. Best grown mounted on tree fern or cork bark, or in small pots with fine-grade bark mix or sphagnum moss.
