Orthotrichum mazimpakanum sp. nov. and O. anodon (Orthotrichaceae), two similar species from California

Abstract Studies of herbarium samples and field surveys in Southern California during the fall of 2008 led to the discovery of several new collections of mosses lacking exostome teeth belonging to Orthotrichum Hedw. subgenus Pulchella (Schimp.) Vitt. Some of them are ascribable to O. anodon F. Lara, Garilleti & Mazimpaka even though they display a set of characters not noticed before, considerably broadening the morphological variability of this species and making necessary an updated description. Other materials, from scattered localities along a wide latitudinal range, correspond to a here described new species, Orthotrichum mazimpakanum Garilleti & F. Lara, differentiated by a set of una…

Orthotrichum pilosissimum (Orthotrichaceae), a new moss from arid areas of Nevada with unique axillary hairs

Abstract Orthotrichum pilosissimum is described from herbarium material and recently collected specimens in the state of Nevada. Its specific epithet refers to the diagnostic hyper-developed axillary hairs, which are frequently longer than 1 mm, multiseriate and branched, covering most of the stems surface and sometimes protruding from the foliose shoots. These hairs are not only unique in the genus but also among mosses, providing a reliable diagnostic character for the new taxon. Additional gametophytic and sporophytic characters that contribute to its taxonomic delimitation are also given.

The long journey of Orthotrichum shevockii (Orthotrichaceae, Bryopsida): From California to Macaronesia

Biogeography, systematics and taxonomy are complementary scientific disciplines. To understand a species' origin, migration routes, distribution and evolutionary history, it is first necessary to establish its taxonomic boundaries. Here, we use an integrative approach that takes advantage of complementary disciplines to resolve an intriguing scientific question. Populations of an unknown moss found in the Canary Islands (Tenerife Island) resembled two different Californian endemic species: Orthotrichum shevockii and O. kellmanii. To determine whether this moss belongs to either of these species and, if so, to explain its presence on this distant oceanic island, we combined the evaluation of…
