Serapias vomeracea, common name Long Lipped Serapias or the Plow-Share Serapias, is a species of orchid in the genus Serapias
Serapias

Etymology

The name Serapias of the genus derives from the Greek Sarapis, the Graeco-Egyptian god, already used in ancient times to name some orchids. The Latin name vomeracea of this species refers to the shape of the apical portion of the labellum (epichile) reminiscent of the ploughshare of a plough.

 perennial plant with two ovoidal underground tubers. This species is highly variable in color and shape. It reaches an height of 20–40 cm (7.9–15.7 ), with a maximum of 60 centimetres (23.6 in). The stem is green, with two membranous basal leaves and 6-8 upper leaves, lanceolate and glossy green or reddish.

The inflorescence is composed by a narrow and elongated spike, with three to ten flowers. The relevant bracts are lanceolate and much longer than the tepal

Reproduction

Serapias vomeracea is an entomophilous plant, but cannot offer floral rewards to pollinators, as it does not produce nectar. Therefore this orchid has a deceptive strategy, as pollinators are just attracted by the shape of the flower, forming a small tube used by insects to rest by night or as a refuge against the rain. In this process the pollen stuck to the pollinators bodies. Once they leave their shelter, they will deposit the pollen on other flowers and will fertilize them. These orchids are mainly pollinated by some beetles (Oedemeridae
