Orthotrichum vittii, a New Epiphytic Moss from Spain

Orthotrichum dagestanicum sp. nov. (Orthotrichaceae, Musci) – a new species from Dagestan (Eastern Caucasus)

“…Orthotrichum vittii, recently described from the Iberian Peninsula (Lara et al, 1999), is similar to O. dagestanicum in naked calyptra, and hyaline hair-point that sometimes is similar although being variable from short and coarsely dentate to long and finely denticulate, as in O. diaphanum. However, O. vittii differs in (1) weakly ribbed urns with only slightly darker ribs vs. strongly ribbed urn with deep furrows and reddish-brown ribs; (2) (Erdag et al, 2004), also shares with O. dagestanicum strongly ribbed urns, 8 paired exostome teeth, recurved and appressed to urn then dry, and naked calyptra.…”

New national and regional bryophyte records, 36

“…The new Russian record extends the range of O. vittii considerably eastward. Another species of Orthotrichum with hyaline leaf tips and strongly ribbed capsules, O. dagestanicum, was recently described from the southern part of the Dagestan Republic (Fedosov & Ignatova, 2010), but the specimen cited here demonstrates all the characters of O. vittii, including the possession of a long hyaline hair point (up to 350 mm, even longer than that described by Lara et al, 1999), and 16 appendiculate endostome segments. R. brunnea is oro-temperate in East Asia, sparsely distributed in Russia (Russian Far East: Sakhalin, South Kuril Islands) and Japan (Hokkaido, Honshu, Shikoku, Kyushu) (Bakalin, 2010;Konstantinova et al, 2009b;Yamada, 1979).…”

“…This is the first record of this species in Russia. It was described from the Iberian Peninsula (Lara et al, 1999) and further recorded in the Western Alps and Atlas Mountains (Medina et al, 2010). The new Russian record extends the range of O. vittii considerably eastward.…”

Orthotrichum pamiricum (Bryophyta), a new epiphytic moss species from Pamir Mountains in Central Asia

“…Orthotrichum pamiricum is similar to O. crenulatum in gametophytic characters, including an obtuse and crenulate leaf apex, but it can be easily distinguished from the latter by the 16 (papillate) endostome segments and a unistratose leaf (Lewinsky, 1992;Schäfer-Verwimp and Gruber, 2002), which is why both of them were found growing together in a few localities along the Tajik-Afghan border. (Lara et al, 1999), and it has not been reported in Central Asia to date.…”
