The drone Ragwurz ( Ophrys bombyliflora ), which also Hummelschweber orchid or brake Ragwurz is called, is a kind of the genus Ragwurzen ( Ophrys ) in the family of the Orchid Family (Orchidaceae).
description
This perennial herbaceous plant has between two and five spherical tubers as persistence organs and reaches heights of growth between 5 and 30 cm. At the base of the stem there are one or two egg-shaped scale leaves. Four to eight leaves are grouped together in a base rosette and in the lower half of the stem there are another one or two long-sheathed leaves.
The inflorescence comprises one to five flowers, most of which the bracts are shorter than the ovary . The broad, egg-shaped sepals are green in color, the middle one is slightly shorter and narrower than the lateral ones. The hairy, broadly triangular petals appear yellow-green. The deep three-lobed lip is dark brown in color. The middle lobe has downwardly curved edges, making it hemispherical in shape. At the front it has a backward-facing appendage, which, however, is not easy to see at first glance. The downwardly curved side lobes have a hairy hump at the base. The inconspicuous mark is brownish to pale purple in color.
The flowering period extends from February to May.
The number of chromosomes is 2n = 36.
Systematics
The drone ragwort is only slightly variable in shape and is usually isolated from other representatives of its genus. But one can distinguish between two varieties:
- Ophrys bombyliflora var. Bombyliflora : It occurs in the Mediterranean and the Canary Islands.
- Ophrys bombyliflora var. Parviflora (Mifsud) Mifsud : It occurs in Tunisia, Malta and Samos.
Distribution and site conditions
The distribution area extends over the Mediterranean area . To the east, the area ends in western Anatolia and Rhodes . This species is the only ragwort found in the Canary Islands . There you can find them on Gran Canaria and Tenerife .
This species prefers light forests, scrubland , poor grassland and little-used cultivated land with moderately dry to moderately moist, but always alkaline soils as a location. This type of orchid can be found in the mountains up to an altitude of 1020 meters.
ecology
Various Eucera species were observed as pollinators .
