- 🌱 The name 'incurvum' refers to the curved or incurved labellum (lip) of the flower, which is a distinctive feature of this species and helps guide pollinators to the flower's center.
- 🌱 This orchid is an epiphyte in its native habitat, meaning it grows on tree branches in tropical forests without harming its host, obtaining moisture and nutrients from the air, rain, and accumulated organic matter rather than from soil.
