The Small Cretan Orchid ( Ophrys cretensis ) belongs to the genus of Ragwurzen ( Ophrys ) in the family of orchids (Orchidaceae). The German trivial name may cause confusion with the Cretan Orchid ( Ophrys cretica ), the kleinwüchsigere but großblütigere of the "Cretan Ragwurzen" is.

features

The Little Cretan Ragwurz is a perennial tuberous geophyte that reaches heights of (15 to) 20 to 50 centimeters. The plant is (2- to) 6- to 11- flowered . The lip is pronounced with 6 to 9 (11) x 7 to 10 millimeter in size, circular to ovoid wide, unsplit, reddish brown to schwärzlichpurpurn and rounded at the base. It has shiny, H-shaped markings. The lateral petals (petals) are 1.5 to 2.5 millimeters wide and greenish in color. The sepals (sepals) are occasionally two-colored: green above, brownish below the middle.

The flowering period extends from February to April, a distinguishing feature from the later flowering Ophrys gortynia , whose lip base also tapers in a wedge shape.

Occurrence

The little Cretan ragwort occurs on Crete , Karpathos (a find with an unclear status ), Paros , Amorgos and possibly other Aegean islands. The species grows in bushes, olive groves, grass corridors and phrygana at altitudes from 0 to 900 meters above sea level.

biology

The pollinator of this ragwort is the sand bee Andrena vachali subsp. creticola .

Taxonomy

Ophrys cretensis was raised to the rank of a separate species by Paul due to the unique combination of characteristics and the specific pollinator . Other authors put it as a subspecies to the Great Spider-Ragwurz (as Ophrys sphegodes subsp. Cretensis H.Baumann & Künkele ). Delforge (2005) places the clan in the relationship of Ophrys mammosa because of the similar lip shape .
