1) The author shows by various citations from Mitten's papers 

 that Mitten always considered his Meteorium lanosum as conspe- 

 cific with the wide-spread and highly variable M. longissirnum Doz. 

 et Molk. Subsequent authors have endeavoured to make two spe- 

 cies, and thereby have caused confusion. The plant appears under 

 both specific names under Aerobryum and under the still more 

 recent Aerobryopsis. 2) The author corrects the names of some New 

 Zealand mosses published by H. Boswell in Journ. Bot. 1898 p. 

 78. 3) Lepidopilum sumatranum v. d. Bosch et Lac. Bry. Java. t. 

 165 is proved to be not distinct from, but identical with, Hookeria 

 utacamundiana Mont. (Lepidopilum Mitt.; Hookeriopsis Br oth. ). 4) Bar- 

 bida rubella (Hoffm.) — the first authority for this combination is 

 S. O. Lindberg, Muse. Scand. p. 22 (1879). 5) Dicranum dichoto- 

 mum (P. Beauv.) Brid. from Bourbon, D. Bülardieri Schwaegr. 

 wide spread in Subantarctic, D. commutatum Hampe and D. tubu- 

 läre Rehm. from the Cape of Good Hope, D. scopareolum C. 

 Müll, and D. patentifolium Ren. et Card, frem Madagascar, are 

 all conspeeific. And though D. Bülardieri is the oldest (1798), yet 

 under the rules of nomenclature (Brüssels, 1910) D. dichotomum 

 (Cecalyphum dichotomum P. Beauv. 1805) takes precedence — Di- 

 cranoloma dichotomum (P. Beauv.) Paris. 6) In revising some Austra- 

 lian species of Cryphidium, the author sbows that C. ovalifolium 

 Broth. has the following Synonyms: Pilotrichum ovalifolium C. Müll. t 

 Cymphaea ovalifolia Jaeg., Cryphaea squarrulosa Hampe, Cryphaea 

 crenulata Mitt. Also that Cryphidium dilatatum Broth. has the syno- 

 nymy: Cryphaea düatata Hk. f. et Wils., Dendropogon Mülleri 

 Hampe, Cryphidium Mülleri Broth. A. Gepp. 



Dixon, H. N., On a collection of Bornean Mosses made 

 by the Rev. C. H. Binstead. i' Journ. Linn. Soc. Bot. XLIII. p. 

 291—323. 2 pl. London, July 1916.) 



The species enumerated were chiefly collected by the Rev. 

 C. H. Binstead in British North Borneo during April— May 

 1913 partly on the north-east coast and partly around Tenom, a few 

 miles from the west coast; to these are added a number of gathe- 

 rings by Crauston and others. A striking feature that is manifest 

 is the peculiar ecological distribution of the genera Syrrhopodon 

 and Calymperes; some twenty or more species of each oeeur in 

 Borneo. They are coastal, without being maritime; they are not 

 hygrophytic; and they usually oeeur on the bark of living or more 

 often of rotting tree-trunk. In all, some 130 species are enumerated; 

 and to several of them critical notes are appended. The following 

 novelties are described: Fissidens (Semüimbidium) autoieus Ther. et 

 Dix., Syrrhopodon trachyphyllus Mont. subsp. albifrons Ther. et Dix., 

 5 (Eu- syrrhopodon § Cavifolii) Ledruanus C. Müll, and var. involu-
