Morphological Description

Diagnosis: The flowers of Trizeuxis are minute and fusion of the floral segments does not physically allow the flowers to open widely. It is quite easy to mistake a plant of Trizeuxis in flower for a species that is only in bud. The miniature fan-shaped plants are immediately recognized the architecture of the inflorescences. The slender wiry panicles have extremely densely congested terminal segments.

Vegetative Morphology

Habit: Miniature caespitose epiphytes producing fan-shaped growths. Pseudobulbs minute, completely concealed by leaf sheaths.

Leaves: Leaves altenate, distichous, strongly bilaterally compressed, rigid-fleshy.
