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.
|Scientific classification |
This hardy plant reaches on average 10–25 centimetres (3.9–9.8 in) of height, with a maximum of 60 centimetres (24 in). The stem is erect and unbranched. The basal leaves are linear-lanceolate with parallel venation, up to 25 centimetres (9.8 in) long, the cauline ones are shorter and barely visible on the stem. The arrangement of hermaphroditic flowers in a compact pyramidal shape is very distinctive and gives the orchid its common name. The colour of the flower varies from pink to purple, or rarely white, and the scent is described as "foxy". The flowers have six tepals, being three small sepals and three petals. Two small petals are on the sides, while the third and lower (labellum) is large and trilobate. At the back of the flower there is a tubular spur of about 1.5 centimetres (0.59 in) long, while the labellum bears two lateral small flaps. The flowering period extends from April through July.
Habitat and Distribution
Anacamptis pyramidalis requires a sunny spot on diverse soils: loamy or clay. It can even grow on very alkaline soil. It can be found on meadows, in grassland, sand dunes, maquis as well as dry and well exposed slopes, to an altitude of 0–1,600 metres (0–5,249 ft) above sea level.
This orchid is native to southwestern Eurasia, from western Europe through the Mediterranean region eastwards to Iran. In Germany, it is rare and was declared Orchid of the Year in 1990 to heighten awareness of this plant. This orchid is especially common on the Isle of Wight in the South of England, and was designated the county plant in 2008. On the Isle of Wight, it favours growth in chalky or sandstone-rich soil, and thus can easily be found on the Downland and cliffs to the west and south of the island.
The flowers are pollinated by butterflies and moths. To ensure the fertilization, their morphology is well adapted to the proboscis of Lepidoptera, especially Euphydryas, Melanargia, Melitaea, Pieris and Zygaena species. The mechanism by which its pairs of pollinia attach themselves to an insect's proboscis was discovered by Charles Darwin and described in his book on the Fertilisation of Orchids.

The variety alba can be found anywhere in the Pyramidal Orchid's range; its flowers are white.
The dried and ground tuber gives a fine white powder, called salep. This is a very nutritious sweet starchlike substance. It is used in drinks, cereals and in making bread. It is also used medicinally in diets for children and convalescents.
