Magarza azulada (Argyranthemum coronopifolium)

Small shrub, up to 1 m. Leaves are obovate, pinnatifid, totally glabrous, rather succulent and bluish-green. Inflorescences have 1-8 heads, with white ligules and a yellow centre, like many other species of the genus Argyranthemum. An endemic of Tenerife, it is relegated to the old massifs of Anaga and Teno. This halo-xerophytic thermophile seldom appears above 300-400 m. A rare, rather localized rupicolous species, it can be common in some places. One of the main threats is from hybridization with A. frutescens, which has been confirmed in Teno. Although all populations of the species grow within the protected areas of Anaga and Teno Rural Parks, the menace of hybridization may lead to its disappearance as an independent species.
