Adonis pyrenaica, common name Pyrenean pheasant's eye, is a species of plant in the family Ranunculaceae.
This very rare species is a native plant of the Pyrenees and the Cantabrian Mountains in southwestern Europe. One station is present in the Maritime Alps of southeast France.[1] [2] It is also cultivated as an ornamental plant.
These orophyte plants prefer rocky mountains, with calcareous or sometimes siliceous scree and stony lawns with discontinuous vegetation, at an elevation of 1300- above sea level.[3]
Adonis pyrenaica has an erect and a little pubescent stem, forming thick tufts measuring approximately 10-. Leaves of this plant are alternate, the lower ones have a long petiole. The plant produces inflorescences showing from one to three yellow flowers, with petals of about 1-. The yellow sepals may be glabrous or slightly hairy. Corolla can reach a width of 5- and it is composed of 10 to 15 obovate petals. Stamens have yellow anthers. The fruits are in the form of achenes of 6–7 mm, from glabrous to densely pubescent.[3] [4]
This perennial herbaceous plant is hermaphrodite. It blooms from June to July and it is pollinated by insects (entomophily), where as seeds are disseminated by the animals.[3]
