asp05 | Rivas-Martínez et al. (1999: 376) placed this unit into synonymy with the Cymbalario-Asplenion, typified it with the Crepido-Erinetum Br.-Bl. 1966 (Braun-Blanquet 1966: 138, Tab. 2) and then suggested to reject it as a nomen dubium (ICPN art. 38). Rivas-Martínez et al. (2011: 213) repeated this suggestion and declared the typus they assigned in 1999 to be a nomen dubium. There is little reason to follow this suggestion since the original diagnoses of both the Crepido-Erinetum and the Sedo albi-Seslerion hispanicae are clear and meet all the requirements of the ICPN. As the only validly described association classified by Braun-Blanquet (1966: 138−140) is the 'Crepis albida-Erinus alpinus Ass.', the latter association unit is automatically the holotypus of the alliance. The nomenclatural type (lectotypus) of the Crepido albidae-Erinetum alpinae Br.-Bl. 1966 is relevé 1 in Table 2 in Braun-Blanquet (1966: 139). (L. Mucina).
