Encalypta rhaptocarpa Schwägrichen and Schistidium rivulare (Bridel) Podpera new moss species from South Sinai, Egypt

South Sinai is the richest phytogeographical territory with mosses in Egypt, as it contains nearly half the number of recorded moss taxa. The topographic and climatic gradients of mountains and wadis develop unique microhabitats for plant biodiversity. These have led to the exceptional bryoflora of South Sinai where 36 moss taxa are restricted in it. Here, we propose a further investigation of the moss flora of South Sinai from the mountain near Saint Katherine Monastery and the surrounding road to the area of Shaq El-lozah. Ninteen taxa were recorded from the area under study. Two of them were new records to the moss flora of Egypt (Encalypta rhaptocarpa Schwägrichen and Schistidium rivulare (Bridel) Podpera). This increases the number of mosses known from Egypt to 201 taxa and from South Sinai to 97. The new recorded species are described and illustrated, with details on the collection sites and habitats. Additional notes are also given on their world distributions, along with some floristic remarks.
