Serapias vomeracea, common name long-lipped serapias or the plow-share serapias, is a species of orchid in the genus Serapias[citation needed].


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.

Serapias vomeracea is an herbaceous perennial plant with two ovoidal underground tubers. This species is highly variable in color and shape. It reaches a height of 20–40 centimetres (7.9–15.7 in), with a maximum of 60 centimetres (24 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 tepals. Their color is red-purple, with darker longitudinal venation. The outer tepals are lanceolate and erect, forming an helmet-like structure. Their color is purple-red or pinkish, with veins of darker color. The internal lateral tepals are brownish-purple and almost entirely hidden by the helmet.

The labellum is brick red, trilobed and larger than the other tepals. The basal portion (hypochile) of the labellum is concave and enclosed in the helmet, with two raised and hairy lateral lobes. The apical portion of the labellum (epichile) is triangular-lanceolate, usually purple-red and quite hairy. The spur is missing. The flowering period extends from March to June.


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 (families Oedemeridae and Lymexylidae) and by bees (genera Ceratina, Eucera and Osmia). The dispersal of seeds is granted by the wind (anemochory).

The species is widespread from south-central Europe, the Mediterranean Basin to the Caucasus.


This orchid prefers dry and wet meadows, pastures, thickets, clearings and scrubland, frequently on clayey substrate, from full light to partial shade, at an altitude of 0–1,200 metres (0–3,937 ft) above sea level.
