This character refers to the structure or appearance of the margins of the labellum.
 |
 |
Wavy: the labellum margins are not divided but curve up and down (undulate). |
|
 |
Convolute/crisped: the labellum margins are extremely wavy, appearing crumpled. |
 |
Toothed: the labellum margins are divided into sharply pointed segments (dentate). |
 |
Lacerate: the labellum margin is irregularly cut, jagged or notched, as if chewed (erose). |
 |
Irregular: the labellum margins are not smooth but have tiny bumps or minute tooth-like structures. |
 |
Incurved: the labellum margins curve inwards rather than being flat. |
 |
Warty: the labellum margins have irregular lumps resembling warts (verrucose). |
 |
Hairy/fringed: the margins have hairs or are cut into slender lobes (fimbriate); the hairs can be simple, cylindrical or tapered structures and can end in a rounded gland. |
 |
Resembling calli/glandular: the labellum margins have lobes that resemble calli found on the upper surface of the labellum or specialised structures that resemble glands. |
