Riella notarisii (Mont.) Mont.

SPECIMEN EXAMINED. — France. Haute-Corse, Barcaggio, temporary ponds d’A Cala, 30.IV.2017, 5 m a.s.l., V. Hugonnot s.n.

Remarks

It was found in great abundance in the Corsican locality in a brackish Mediterranean pond with mix water supply (sea water and meteoric water). Riella notarisi , as most of species of the genus, is a typical species of clean, shallow temporary ponds ( Segarra-Moragues et al. 2014). It is a halotolerant subneutrophilous-basiphilous species (Dierβen 2001).

The determination of the sexual condition may offer special difficulties since antheridia are difficult to locate; they are hidden in a profusion of vegetative appendages very close to the growing point at the margin of the developing wing. The accurate determination of Riella notarisi relies heavily on its monoecy ( Casas et al. 2009).

Riella notarisi is an European-Mediterranean species, which distribution includes Central Europe ( Bischler 2004). In the Mediterranean Region it is recorded from the Canary Islands in Macaronesia; the Balearic Islands, Crete, Croatia, France, Greece, Portugal, Sardinia, Sicily and Spain in southern Europe; Algeria, Morocco and Tunisia in northern Africa ( Bischler 2004; Ros et al. 2007). In Southern France, it is recorded patchily in Hérault, Bouche-du-Rhône, and Var Departments ( Crozals 1903; Skrzypczak 2001, erroneously sub Riella parisii Gottsche (specimen N° 1048 from French Groupe d’Échange des bryophytes, leg.
