Name: Porroglossum hystrix

Etymology: The genus name Porroglossum refers to the distinctive form and function of the mobile lip. The Greek-Latin specific epithet hystrix means “porcupine” and alludes to the flower’s conspicuously bristly or spiny appearance.

Origin/Distribution: The Andean region of South America.

Location/Habitat: This species grows epiphytically in humid montane to cloud forests. We recommend partial shade to bright, diffused light, high humidity, and continuous air movement. Cool to intermediate conditions of approximately 10–22 °C (50–72 °F) during the day and 6–15 °C (43–59 °F) at night are favorable; prolonged heat should be avoided.

Description and Notes: Porroglossum hystrix is a compact, pseudobulb-free orchid with small leaves and delicate inflorescences. The flowers have conspicuous, bristle-like structures and the mobile lip characteristic of Porroglossum. We grow this species in a fine, very airy substrate that retains some moisture, or mounted with appropriately high humidity. We water regularly with water that is as soft as possible and avoid both allowing the plant to dry out completely and waterlogging.
