Notes on mosses from Ceylon and India, 8. Another moss with three names in three continents

Abstract

Entodon dregeanus (Hornsch.) C.M., from Africa arid E. plicatus C.M., from southern India and Ceylon, are reduced to the synonymy of E. macropodus (Hedw.) C.M., an American species.     

Some species ofCamposporium Harkn. from India

Camposporium indicum, C. hyderabadense andC. microsporum are described as new species. They were collected from dry leaves ofBorassus flabellifer L. A key to the Indian species of the genusCamposporium is given.     

Notes on the nomenclature of British mosses. II

Abstract

Paul Westmacott Richards (19 December 1908–4 October 1995) was for 75 years a member of ‘the Society’ (the Moss Exchange Club, MEC, later to become the British Bryological Society, BBS) and was, by some very considerable margin, its longest standing member (Figs 1–4). He was President of the BBS on two occasions (1950–51 and 1978–79), an office that no one else has held twice. He was elected an Honorary Member in 1970. From 1949 until 1976 he was Professor of Botany at the University College of North Wales (now University of Wales, Bangor).     

Notes on the nomenclature of British mosses. I

Abstract

Gemmae found on the protonema of Barbula trifaria are described. The protonemal gemmae of this species and of Gyroweisia tenuis and Eucladium verticillatum, in addition to those recently reported in Schistostega pennata, seem to be adaptations for survival and propagation at low light intensities.     

Notes on the mosses of Rhodes and Kos

Abstract

The habitat of glaciokarst plains in the Dolomites corresponds to ancient cirques carved by glaciers during the Pleistocene era and now determined by karstic processes. It has a rich bryological flora (eighty-seven species). Some of them proved to be statistically significant for indicating vegetation types. The latter are clearly correlated with different types of karstic landforms, each of which corresponding to a well-defined microenvironment.     

Some mosses of Rarotonga,Cook Island Group

Abstract

Approximately fifty mosses collected are reported from Rarotonga, the largest island of the Cook Archipelago. A very low level of endemism is apparent and the dominating phytogeographic component is Oceanic with secondary Austral and Indomalayan-Asian elements.     

Notes on Guayana mosses with new information of Sphagnum ornatum

Mosses restricted to tepui summits in the Guayana Highland are relatively few.Sphagnum ornatum Crum, though, only recently described from Brazil, has been found subsequently in a number of localities in nearby Venezuela and Guyana. These additional collections make for a better understanding of the diagnostic features of a species characteristically found on the tops of the sandstone mesas of southern Venezuela and adjacent areas.
