Porpax extinctoria

Porpax extinctoria, also known as Conchidium extinctorium or Eria extinctoria, is a diminutive epiphytic orchid native to regions including Nepal, Bangladesh, Myanmar, and the Andaman Islands. This species is characterized by its leafless, flattened pseudobulbs and tiny, delicate flowers that emerge from the tops of these bulbs.

Features:

• Size: The plant is compact, with pseudobulbs measuring approximately 3.0 cm wide, 4.0 cm tall, and 0.7 cm deep.

• Flowers: Each inflorescence can bear up to six single flowers, each about 1.5 cm in length and 1.0 cm in width. The flowers are white with a pale yellow lip and orange keels, and the column is white with a bright yellow foot.

• Growth Habit: Porpax extinctoria is a mat-forming epiphyte with cylindrical pseudobulbs that remain leafless.

Care Tips:

• Light: Provide bright, indirect light. Direct sunlight should be avoided to prevent potential damage to the plant.

• Temperature: Maintain temperatures between 13–29°C (55–85°F).

• Humidity: Ideal humidity levels range from 60% to 80%.

• Watering: Water the plant regularly during its active growth period, ensuring the medium remains moist but not waterlogged. During dormancy, reduce watering to prevent root rot.

• Fertilization: Use a balanced, water-soluble fertilizer at one-quarter to one-half strength every 4–6 weeks during the growing season.

• Mounting: Grow Porpax extinctoria mounted on small slabs without a pad of moisture-retaining material at the roots. This setup mimics its natural epiphytic habitat and promotes healthy growth.
