excurrent ; (:^)) Bryum SetcheUii, closely allied to B. agattimise Phil., 

 from which it is distinguished by its less obtuse leaves, its numerous 

 slender, brittle branches, and more evolute peristome ; (4) Hypnum 

 pseudo-sarmentosum, distinguished from H. sarmentosum Wahl. by its 

 acuminate-acute leaves. 



North American Muscineae. — A. J, Grout * publishes some notes 

 on Vermont Bryophytes, chiefly collected on and near Mt. Mansfield. 

 Among the species recorded are TayJoria tenuis, Schistostega, Swartzia 

 moatana, Amphidmm Japponicum, RhaMoiveisia denticulata, Cynodontium 

 gracilesc67is, Amblystegium racillans, Plagiothecium eUgam, Pohlia cruda, 

 and remarkably varying forms of Pohlia nutans. 



E. G. Britton f makes her seventh contribution of notes on nomen- 

 clature, treating of the North American genera of Xeckeraceffi, included 

 in Engler and Prantl's " Pflanzenfamilien." 



C. C. Haynes % gives figures of ten species of Lophozia, to illustrate 

 descriptions borrowed from A. W. Evans's " Notes on New England 

 Hepaticas." 



J. M. Holzinger§ has for twelve years studied the natural growth of 

 Physcomitriuni immersum,, and has never succeeded in finding more than 

 a few plants of it in a tuft. It usually occurs isolated among the fol- 

 lowing hepatics — terrestrial forms of Ricciocarpus nutans and R.fluitans, 

 associated with Anthoceros JIacounii: and with it often occurs Bphe- 

 merum crasiilnervium., with abundant protonemata. 



Vancouver Hepatic8e.|| — A. W. Evans gives a list of 71 hepaticas 

 of Vancouver Island. In an historical survey he shows that the 

 first records were three species reported by Mitten in lK5i) ; in 1890 

 55 species were recorded by Pearson, which total was raised to 66 by 

 Underwood in 1902. Of the 71 species reported from the island by 

 Evans, 54 are common to Europe, 43 to New England, and 14 are con- 

 fined to the Pacific Coast of North America. 



South American Mosses.lF — I. Theriot gives a list of ten mosses 

 collected near Bogota, in New Granada, by Pere ApoUinaire-Marie. 

 There are two new species of Leptodontium, which are described by 

 Brotherus and figured by Theriot. 



Bryophyta of Ascension.** — R. N. Rudmose Brown gives a list of 

 five mosses and five hepatics collected by him on Elliott's Pass, at an 

 altitude of 2000 ft., on Green Mountain, in the Island of Ascension. 

 One of the hepatics is a new record for the island. 



Moss-flora of Leipzig.tf — W. Monkemeyer has studied the moss-flora 

 of the district round Leipzig. Until quite recently there was a flora of 

 about 100 Muscineae in a small area on and about an outcrop of clay at 

 Gautzsch. Four new species of Bryum from that place were described 

 by Hagen in 1904, and a wealth of forms of Drepanocladus and other
