Although formerly included in A. glan- endemic taxa distributed in the Canary and Madeira dulosa Lam., the new species differs remarkably from archipelagos (Jardim & Menezes de Sequeira, 2008; Madeiran populations by its woolly stellate pubes- Acebes Ginove´s et al., 2010). The Madeira Archi cence, scattered glandular pubescence restricted to pelago hosts A. integrifolia (recently introduced), A. the peduncles and involucral bracts, peduncles crithmifolia Aiton (a rare endemic), and A. glandu flattened and enlarged at the base of the capitula, losa Lam.

Andryala perezii has a habit latter including A. glandulosa subsp. glandulosa and similar to that of the Canarian A. pinnatifida Aiton A. glandulosa subsp. cheiranthifolia (L’He´r.)

Santos and A. peduncles; and smaller cypselae with a ring of short pinnatifida Aiton, the latter including four subspe teeth at the apex equivalent to the height of the cies: A. pinnatifida subsp. pinnatifida, A. pinnatifida prolongation of the ribs.
