“…Afro-American disjunct mosses have been compiled by Delgadillo (1993), but it is a list of all species that the Americas share with Africa, not species found exclusively on both continents and not recorded elsewhere. The tentative unpublished list of such mosses consists of over 80 species, which are common to both continents (Ochyra & Plášek, 2019). This paper reports two additional moss species that exhibit an Afro-American distribution pattern.…”

Two American species of moss, Ephemerum homomallum Müll. Hal. (Pottiaceae) and Torrentaria aquatica (A. Jaeger) Ochyra (Brachytheciaceae), are reported as new to Africa, based on collections from the Limpopo and Eastern Cape provinces of South Africa, respectively. These discoveries changed the phytogeographical status of both species, which now belong to the Afro-American distribution element. Global geographical ranges of these two species are reviewed and mapped, and the amphiatlantic distribution pattern of mosses is briefly summarized. A history of the muscological exploration of southern Africa is briefly considered and recent additions to the moss flora of this area are reviewed.

“…This is because I. ambiguum Cardot, another species of this genus reported from this archipelago, proved to be conspecific with I. tenerifolium Mitt. (Ochyra & Plášek, 2019), an Afro-American species, widespread in the Neotropics and once found in the Cape in South Africa (Ochyra & Ireland, 2016). In addition, there is another species of this genus, I. brownii Cardot, known from Gough Island in the southern group of the archipelago (Cardot, 1911(Cardot, , 1912.…”

The original material of Isopterygium tristaniense Dixon, an endemic species of the Tristan da Cunha archipelago in the central South Atlantic Ocean, is taxonomically evaluated and some details of its morphology are illustrated. The species is found to be conspecific with the Holarctic Pseudotaxiphyllum elegans (Brid.) Z.Iwats. and it is the third record of the species in the Southern Hemisphere. The global distribution of this species is reviewed and the distribution patterns of the South Atlantic mosses are briefly discussed.
