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 a ploughshare.
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, 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 pollen gets stuck to the pollinators' bodies. Once they leave their shelter, they will deposit the pollen on other flowers and fertilize them. These orchids are mainly pollinated by some beetles (families Oedemeridae and Lymexylidae) and by bees (genera Ceratina , Eucera and Osmia ). Seeds are dispersed by the wind (anemochory).
The species has a Mediterranean- Atlantic distribution from Charente in the north and is widespread from south-central Europe, the Mediterranean Basin to Cyprus. [1]
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.
Ophrys apifera, known in Europe as the bee orchid, is a perennial herbaceous plant of the family Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, as well as of a highly selective and highly evolved plant–pollinator relationship.
Anacamptis pyramidalis, the pyramidal orchid, is a perennial herbaceous plant belonging to the genus Anacamptis of the family Orchidaceae. The scientific name Anacamptis derives from Greek ανακάμτειν 'anakamptein' meaning 'bend forward', while the Latin name pyramidalis refers to the pyramidal form of the inflorescence.
Gymnadenia conopsea, commonly known as the fragrant orchid or chalk fragrant orchid, is a herbaceous plant of the family Orchidaceae native to northern Europe.
Dactylorhiza fuchsii, the common spotted orchid, is a species of flowering plant in the orchid family Orchidaceae.
Anacamptis morio, the green-winged orchid or green-veined orchid, is a flowering plant of the orchid family, Orchidaceae. It usually has purple flowers, and is found in Europe and the Middle East.
Coeloglossum is a genus of flowering plants in the orchid family Orchidaceae. It has long been considered to have only one species, Coeloglossum viride, the frog orchid. Some recent classifications regard Coeloglossum as part of the larger genus, Dactylorhiza, so that C. viride becomes Dactylorhiza viridis. Other sources continue to keep Coeloglossum viride separate.
Orchis mascula, the early-purple orchid, early spring orchis, is a species of flowering plant in the orchid family, Orchidaceae.
Antirrhinum majus, the common snapdragon, is a species of flowering plant belonging to the genus Antirrhinum. The plant was placed in the family Plantaginaceae following a revision of its prior classical family, Scrophulariaceae.
Dactylorhiza maculata, known as the heath spotted-orchid or moorland spotted orchid, is an herbaceous perennial plant of the family Orchidaceae. It is widespread in mountainous regions across much of Europe from Portugal and Iceland east to Russia. It is also found in Algeria, Morocco, and western Siberia.
Orchis patens is a species of orchid found from the central Mediterranean to northwestern Africa.
Orchis provincialis, the Provence orchid, is a species of orchid in the genus Orchis.
Oreocallis is a South American plant genus in the family Proteaceae. There is only one species, Oreocallis grandiflora, which is native to mountainous regions in Peru and Ecuador.
Stachys recta, commonly known as stiff hedgenettle or perennial yellow-woundwort, is herbaceous perennial plant of the family Lamiaceae.
Caladenia attingens, commonly known as mantis orchid, is a species of flowering plants in the orchid family Orchidaceae and are endemic to the south-west of Western Australia. There are three subspecies, each of which has a single hairy leaf and one or two brightly coloured flowers with upswept sepals and a labellum with long, comb-like fringes. The subspecies differ in size, distribution and habitat.
Caladenia huegelii, commonly known as the grand spider orchid is a species of orchid endemic to the south-west of Western Australia. It has a single, hairy leaf and up to three relatively large red, green and cream-coloured flowers which have "split-hairs" on the sides of the labellum.
Eriochilus dilatatus, commonly known as the white bunny orchid, is a plant in the orchid family Orchidaceae and is endemic to Western Australia. It is a common and widespread, slender ground orchid with a single leaf and up to fifteen small white and greenish flowers with reddish or brownish markings and a hairy labellum.
Caladenia lateritica, also known as white primrose orchid, is a plant in the orchid family Orchidaceae and is endemic to relatively inaccessible, high lateritic plateaux in a high rainfall area in south-western Western Australia. It is a ground orchid with a single hairy leaf and one or two white flowers on a thin, sparsely-hairy stem. It is similar to Caladenia flava but is distinguished by its fragrant white versus yellow flowers with prominent red stripes and spots on the dorsal sepal and lateral petals. Caladenia lateritica mimics Conostylis setosa (Haemodoraceae) in terms of flowering time, height, colour and fragrance. It also shares a native bee pollinator with Conostylis setosa, which provides pollen and nectar whereas the orchid is rewardless.
Caladenia rosea, also known as pink primrose orchid, is a plant in the orchid family Orchidaceae and is endemic to relatively inaccessible, high lateritic plateaux in a high rainfall area in south-western Western Australia. It is a terrestrial orchid with a single hairy leaf and up to three pink flowers on a thin, sparsely-hairy stem. It is similar to Caladenia flava but is distinguished by the perianth being pink to dark pink with prominent red striping and spotting on the dorsal sepal and lateral petals. Caladenia rosea mimics Hypocalymma robustum (Myrtaceae) in terms of flowering time, colour and scent.
The pollination of orchids is a complex chapter in the biology of this family of plants that are distinguished by the complexity of their flowers and by intricate ecological interactions with their pollinator agents. It has captured the attention of numerous scientists over time, including Charles Darwin, father of the theory of evolution by natural selection. Darwin published in 1862 the first observations of the fundamental role of insects in orchid pollination, in his book The Fertilization of Orchids. Darwin stated that the varied stratagems orchids use to attract their pollinators transcend the imagination of any human being.
In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
