The Phalaenopsis amabilis labellum or part of the flower that attracts insects, is white with yellow and reddish markings, and has a large callus at the base.
The labellum is white with yellow and reddish markings, about 25 millimetres (0.98 in) long with three lobes. There is a large yellow callus near the base of the labellum. In botany, the labellum (or lip) is the part of the flower of an orchid or Canna, or other less-known genera, that serves to attract insects, which pollinate the flower, and acts as a landing platform for them.
