654 SUMMARY OF < URBBNT RESEARCHES RELATING TO 



Philonotis revised by Dismier.* — E. Gt. Britton makes some critical 

 remarks on ( '. Dismier'sf revision of the American species of Philonotis, 

 and riles sonic eleven American species which lie lias not included in his 

 work. <>ut of seventy-four species recorded for America, Dismier has 

 reduced forty to synonyms. Authors in the past have been too free in 

 the creation of species. 



E. B. Chamberlain % gives a translated resume of Dismier 's revision, 

 giving the key to the twenty-five species in full, and a synoptic account 

 of the twelve North American species, with the addition of synonyms 

 and descriptive notes. 



Hyophilopsis, a New Indian Moss-genus.§ — H. X. Dixon gives an 

 account of some thirty Indian mosses from the districts of Poona, 

 Mysore, the eastern Himalayas, and Assam. Among them is Hyo- 

 philapsis, a new genus of Pottiaceae, with fruiting characters very near 

 to those of Hyopliila, but with the leaf-areolation of a Pottia. The leaf- 

 cells, moreover, are seriately papillate. It contains one new species. 

 Critical notes are appended to several of the plants recorded ; and in all. 

 five new species are described and figured. 



Wollnya, a Genus of Bryacea3.|| — T. Herzog gives an account of 

 Wollnya, a recently published genus of mosses related to Leptobryum. 

 He enlarges the genus by including in it Bryum Wilsoni Mitt., an 

 Andine species. The type of the genus is W. stellata Herz. The author 

 figures both species, and now fixes definitely the position of Wollnya 

 among the Bryese. It differs from Leptobryum principally in leaf- 

 structure. 



Swartzia inclinata in Lancashire, f — J. A. Wheldon notes the 

 similarity of the Lancashire sand-dunes to those of Tent's Muir and 

 Barrie on the east coast of Scotland, and states that chance alone is 

 insufficient to account for the presence, in areas so widely separated, of 

 such rarities as Bryum Marrattii, B. calophyllum, B. Warneum, B. neo- 

 damense, Catoscopium nigritum, Hypnum Wilsoni, H. lycopodioides. To 

 these may now be added Sivartzia inclinata, recently found well estab- 

 lished near Freshfield. It had previously been recorded for an inland 

 situation in south Lancashire, and caused some speculation as to its 

 origin. 



Notes on Grimmia.** — P. Culmann publishes notes on some species 

 of Grimmia. He gives a description and figure of 67. teryestinoides, a 

 novelty which, if not a sub-species of G. teryestina, is a remarkable 

 variety, found in the Swiss Jura. The allied species 67. poecilostoma 

 Cardot, must, it is found, assume the prior name of 67. Cardoti Heribaud. 

 Culmann agrees with Breidler and Hagen that G. sessitana and 67. sub- 

 sulcata belong to one and the same species, but does not accept Hagen's
