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.
Reproductive Morphology
Inflorescence: Inflorescences erect axillary pedunculate panicles. Flowers minute, barely opening, yellowish-white.
