Abstract
ABSTRACT Introduction During field studies in Argentina, we collected a specimen of Aloina Kindb. that did not match any of the known species of the genus. Here we present our arguments for recognising this moss as a new species. Methods The morphology of the new taxon was compared with that of the species of Aloina presently recognised. In addition, most of the type material of the taxa attributed to this genus in the world has been studied. Key results and conclusions Aloina scindulosa M.J.Cano, J.A.Jiménez & M.T.Gallego is described and illustrated as a new moss species from four localities in the Monte Desert area of Argentina. It is distinct from all other members of the genus in the combination of its lingulate leaves with unbordered margins, rectangular and slightly sheathing leaf bases, leaves ending in a long, hyaline, papillose hair-point near the leaf apex, the costa scarcely differentiated, in cross-section with no stereids, and the upper and middle laminal cells and costal surface dorsally prorate in the upper midleaf. Possible confusion with other species of the genus is discussed. A key to the South American species of Aloina is provided.
期刊介绍:
Journal of Bryology exists to promote the scientific study of bryophytes (mosses, peat-mosses, liverworts and hornworts) and to foster understanding of the wider aspects of bryology.
Journal of Bryology is an international botanical periodical which publishes original research papers in cell biology, anatomy, development, genetics, physiology, chemistry, ecology, paleobotany, evolution, taxonomy, molecular systematics, applied biology, conservation, biomonitoring and biogeography of bryophytes, and also significant new check-lists and descriptive floras of poorly known regions and studies on the role of bryophytes in human affairs, and the lives of notable bryologists.
