Locally frequent on the northern side of La Gomera.
Restricted distribution on Fuerteventura but locally common.
Occurs on La Palma where recent forest fires have almost certainly affected all the main populations of this species.
As previous species, this local La Palma endemic is seriously threatened by the effects of forest fires which recently destroyed almost 50% of the forests of the island.
Occurs on Tenerife, Gran Canaria, La Palma, La Gomera and El Hierro, very common.
A rare species with individual endemic island subspecies which form part of the diversity of the species and should be protected. The species is probably not monophyletic, each subspecies probably being of independent origin and so it is an important taxon from an evolutionary point of view.
Common on La Palma but declining along with its forest habitats.
Occurs on Tenerife, Gran Canaria, La Palma, La Gomera and El Hierro, common and colonising walls.
Sometimes confused with the previous species, seems to be in an expansion phase in the north of Gran Canaria.
Occurs on Tenerife, Gran Canaria, La Palma, La Gomera and El Hierro, very common but polymorphic and its genetic diversity should be taken into account for conservation.
About 17 species but in need of a good revision; recent attempts have only added to the problems and the basis provided by Praeger in the 1930s is still valid.
A few scattered populations in the south of Tenerife, over-collected.
Common on the north side of La Gomera.
Still locally quite common but confined to the Anaga hills at the eastern end of Tenerife.
Occurs on Tenerife and Gran Canaria, common but polymorphic and conservation measures should take the possible genetic diversity into consideration.
Tenerife, restricted distribution but locally very abundant.
Occurs on all the islands; any conservation plan for this species should, however, take into account its extreme polymorphism.
May be the same as M. adenoscepes but needs revising.
Occurs on Tenerife, La Palma and La Gomera, locally common.
High mountain species, over-collected but now in Teide National Park and protected.
Occurs on Tenerife, locally common.
Occurs on Tenerife, very common.
Single locality on the north coast of Tenerife.
Occurs on Gran Canaria; this is probably one of the many local forms of M. brachycaulon.
Occurs on Tenerife and La Gomera; needs taxonomic revision, appears to be common but confused with M. muralis.
Tenerife, single locality, recently described species.
Locally abundant on the Famara cliffs of Lanzarote and not threatened. Main habitat is in a protected area.
This genus of four species has no threatened taxa even though two species are restricted in distribution, G. dodrentalis (its western Tenerife localities are in protected areas) and G. aizoon. protected in the Guimar natural park.
Tenerife, La Gomera, Gran Canaria, protected at Teno, Tenerife and the largest populations on Gran Canaria will come within the proposed Roque Nublo National Park.
Abundant in the west and south of Tenerife where many populations are within the protected areas network.
Widespread colonizing species abundant on all the islands in coastal regions.
Endemic to La Gomera but locally common especially in the east and southeast.
Remains, this species should be brought into cultivation and restocking used to augment the natural population.
Two main localities, Riscos de Agulo with few plants but in a protected area and Majona which is a Natural Park with a relatively large population. A recovery plan should be included in the Park management programme.
Tenerife, La Palma, La Gomera, El Hierro, the comment under the previous species also applies here.
Common on most islands but rather rarer on La Gomera and with only a few localities on Lanzarotc (Malpais de la Corona) and Fuerteventura (mainly Jandia).
Declining species threatened by tourist development and over-collecting, its main remaining populations arc protected in theory but are still declining especially due to the removal of young plants. The species should be strictly protected in its natural habitat.
A local segregate of the previous species Gomera where three main populations occur; two of these arc within the National Park and if correctly managed this species should survive without too many problems.
Extremely rare species of Tenerife, La Palma and La Gomera. It is almost extinct in all its known localities where populations are reduced to single figures with 1-5 individuals only. All localities should be protected and reintroduction considered.
