190 SUMMARY OF CUKKENT RESEAKCHES RELATING TO 



being in Ireland. (4) CepliaJoziella integerrima Warnst. was found by 

 Nicholson in Sussex at two stations. Macvicar shows how it differs 

 from C. Bryhnii, and resembles Cpiri flora Douin. 



Rhacomitrium ramulosum : a British Moss.* — W. Young gives 

 an account of a moss which he gathered on Craig Mohr, Perth, in July 

 1S98, and which, after being referred for some years to R. sudeticum 

 and R. hderostkham var. gracilescens, is now recognised to be R. ramu- 

 losum Lindb. — a moss long supposed to be a doubtful native, having 

 been recorded seventy years ago by Hooker from the Highlands, but 

 without special habittit. Recently, however, it was gathered by Stirton 

 in Lewis, and by Lillie in Caithness. A critical note by Dixon is 

 added. 



Bryological Work of William Mitten. t — W. E. Nicholson gives a 

 sketch of the life of William Mitten (b. ISll) ; d. I'.IOG), who devoted 

 the leisure hours of his long life to the study of the Muscineas of 

 Britain and of the whole world. In the appended bibliography fifty- 

 seven of his bryological contributions are cited, treating of bryological 

 collections from all parts. His most important work, the " Musci 

 Austro-Americani," occupies the twelfth volume of the Journal of the 

 Linnean Society. Of great importance also are his enumerations of the 

 mosses and hepatics of India, New Zealand, Tasmania, Samoa, Ceylon, 

 of the ' Challenger ' and Transit of Venus Expeditions. 



Census of Australian Mosses. | — "W. W. "Watts and T. Whitelegge 

 have compiled a classified catalogue of the acrocarpous mosses of Aus- 

 tralia and Tasmania, collated from available publications and herbaria. 

 The catalogue comprises 018 species, '.)0 of which appear to be new to 

 science, but are published without descriptions. Indeed, many of the 

 new species are known only by name in Australia, having been determined 

 in Europe. The compilation of the list was rendered the more difficult 

 by the inaccessibility of descriptions and specimens, and by the different 

 principles of -determination and classification adopted by specialists. 

 Hence the present census is intended as a working list. A bibliography 

 of papers on Australian mosses is appended. 



Mosses from Alaska.§ — J. Cardot and T. Theriot describe a small 

 but .very interesting collection of mosses made by W. A. Setchell and 

 others in the summer of 1899. It comprises 6;') species and several 

 varieties, of which 4 species are new to science and 6 new to Alaska. 

 The 4 new species are (1) Orthotrichum cancellatum, nearly related to 

 O.fenestratum, but differing in its smaller size, shorter stems, shorter 

 and more papillose leaves and immersed capsule, sulcate when dry ; (2) 

 Bryum pseudo-Grcefianum, which differs from B. Grmfianum SchKeph. 

 and B. Kaurmianum "Warnst. by its paler capsule and its shorter, 

 smaller, and more shortly acuminate leaves, with the costa not so longly
