In the last years, the studyof unstable bottoms occupied by pebbles or rocks without perennial vegetation due to theabrasion by sand, it has allowed to discover a rich and diverse ephemeral flora, that wasoverlooked. This flora is constituted by species of Ganonema, Helminthocladia, Helminthora, Naccaria, Reticulocaulis, Acrosymphyton, Schimmelmannia, Calosiphonia, Dudresnaya,Thuretella and Predaea; genera with gelatinous gametophytes, heteromorphic life histories,and primitive structures and reproduction. In this paper we review the knowledge on this surprising flora, emphasizing the high diversity that it is to catalogue in many sulittoral habitatsof the Canary Islands not yet sufficiently explored YR 2009 FD 2009 LK http://riull.ull.es/xmlui/handle/915/26155 UL http://riull.ull.es/xmlui/handle/915/26155 DS Repositorio institucional de la Universidad de La Laguna RD 04-jun-2024
