Ophrys omegaifera subsp. dyris - Omega Ophrys

Phylum: Magnoliophyta - Class: Liliopsida - Order: Orchidales - Family: Orchidaceae

Ophrys dyris

This orchid is often simply referred to as Ophrys dyris and it is reminiscent of a host of other similar-looking but highly variable ophrys species found throughout the Mediterranean region.

Description

Although superficially similar to Ophrys fusca, this orchid has several features which clearly set it apart. It grows up to 50cm in height (generally taller than Ophrys fusca) and the flowers are noticeably convex and coated with a thick layer of white hairs. The shape of the flower is often described as resembling a boxing glove. The lip displays the Greek omega, a W-shaped speculum which gives it the common English name of Omega Ophrys. Each lax inflorescence can carry up to 10 flowers.
