Corybas ecarinatus

Corybas ecarinatus is a rare and enigmatic terrestrial orchid species native to southern Thailand. Belonging to the Corybas genus, known for its distinctive helmet-shaped flowers, this species is notable for its unique morphology and specific ecological requirements.

Features:

• Distribution: Endemic to southern Thailand, particularly in regions like Phang-Nga province.

• Elevation: Typically found at around 550 meters above sea level.

• Flower Size: Approximately 5 mm across.

• Blooming Period: Blooms in autumn, with growth occurring in spring and summer. The plant drops its leaves in autumn and winter.

• Flower Structure: The flower features a large dorsal sepal that forms a hood over the column, characteristic of the Corybas genus.

Care Tips:

• Light: Provide bright morning light or shaded afternoon light. Avoid direct midday sun to prevent leaf scorch.

• Temperature: Maintain warm temperatures during the growing season:

  • Daytime: 30°C–35°C (86°F–95°F)

  • Nighttime: 22°C–28°C (72°F–82°F)

  • During dormancy, provide cool temperatures:

  • Daytime: 18°C–25°C (64°F–77°F)

  • Nighttime: 10°C–15°C (50°F–59°F)

• Humidity: High humidity is essential. Aim for 70–85% relative humidity. Utilize a terrarium or humidified environment to maintain moisture levels.

• Watering: Keep the substrate consistently moist but not waterlogged. Use distilled or rainwater to prevent mineral buildup. Avoid allowing the substrate to dry out completely.

• Substrate: Grow on sterilized sphagnum moss, wet wood, or wet rocks. Ensure the substrate remains moist and free from competing mosses or other plants that could smother the fern.

• Air Circulation: Maintain minimal air movement to prevent desiccation. While some airflow is necessary to prevent mold, excessive ventilation can dry out the delicate fronds.

• Fertilization: Fertilize sparingly. Use a diluted, balanced fertilizer during the growing season, but avoid over-fertilizing, which can harm the plant.
