Consequences of hybridization processes in the intergenic spacer of ribosomal DNA in Armeria (Plumbaginaceae)

Poster presentado al International Conference on Polyploidy, Hybridization and Biodiversity, celebrado en Rovinj, Croacia del 11 al 14 de mayo de 2016The hybridizing genus Armeria. Armeria Willd. is a genus of flowering plants belonging to family Plumbaginaceae. The genus counts over a hundred species mostly native to the Mediterranean area, although there are some exceptions such as Armeria maritima Willd. (Figure 1), which is distributed along the coasts of the Northern Hemisphere, including the British Isles. Armeria pungens (Link) Hoffmanns. & Link (Figure 2), is a perennial shrub that grows on sandy maritime dunes (exceptionally on sandy soils over limestone maritime cliffs) with a main geographical distribution (Figure 3) along a 500 km coastal stripe in southwest Iberia, from the mouth of river Tajo to the Gibraltar strait. It also occurs on continental islands: in the Atlantic, on the Cíes Islands (offshore Galician coast, Northern Spain), and in the Mediterranean, on South Corsica and North Sardinia. Armeria pungens grows forming small shrubs, reaching heights of about 80 cm. The stems are lignified at the base, robust and highly branched. Leaves are glabrous, linear to lanceolate, pointed, about 60 - 150 mm long and about 1 - 3.5 mm wide. Flower heads are pale pink, gathered in globular inflorescences at the top of long pedicels. The flowering period extends from May through July.This work was supported by the Dirección General de Investigación Científica y Técnica, government of Spain (CGL2013-49097-C2-2- P), the Generalitat de Catalunya, government of Catalonia ("Ajuts a grups de recerca consolidats", 2014SGR514), the IRBI0 (“Institut de Recerca en Biodiversitat”) and the Czech Science Foundation (P501/12/G090).
