GROUT, A. J., Th e Peristo me. II. (The Bryologist. V. July 



1902. p. 53—56. pl. 5, f. A.) 



Additional observations made upon the peristome oi Georgia 

 necessitate extentions oi the Statements made in The Bryologist, April 

 1901. The adaptation oi the peristome to the distribution of the spores is 

 discussed and a description of the conditions obtaining in some oi the 

 Polytrlchaceae is given. Plate 5, figs. 6, 7 and 8 shows diiferent posi- 

 tions of the peristome of Barbula amplexa. Moore. 



Hill, E. J., Fissidens grandlfrons, its habits and propa- 

 gation. (The Bryologist. V. July 1902. p. 56— 58. f. 1—6.) 



Plants growing on sandstone from „Starvec! Rock" near Utica, Jll. 

 Records the asexual propagation of F. grandifrons by means of axillary 

 buds which grow into rooting shoots. Moore. 



HOLZINGER, John M., Sellgeria Tristicholdes Kindb. (The Bry- 

 ologist. V. July 1902. p. 62—64.) 



A discussion oi the indentity of <S. tristicholdes and 5. tristicha. 

 A close comparison oi American material with the Swedish plant 

 seems to show a slight difference, the former having a shorter apical 

 cell and the costa runs clear up to it, — the latter having a longer 

 apical cell and the costa ceasing some little distance below, leaving the 

 apex of but one cell layer. Moore. 



RENAULD, F., Gallier gidium vice Pseudo-calliergon Ren. (The 



Bryologist. V. July 1902. p. 64.) 



Corrects the duplication of Pseudo-calliergon Limpr. Laubmoose 

 III., p. 547) in Bryologist IV., Oct. 1901, p. 63) by proposing the name 

 C alller gidium and transfers to this new subgenus Hypnum Tundrae 

 Arnell, Hypnum Bakeri Ren., Hypnum pseudostramlneum C. Muell. and 

 Hypnum pleslostramineum Ren. Moore. 



Britton, Elizabeth G., The genus Sematophyllum. (The Bry- 

 ologist. V. July 1902. p. 64—66.) 



A discussion of the views of various authors on the position of 

 this genus. The füll synonymy of the eight American species is given.

Bryologist. V. July 1902. p. 66—67.) 



In The Bryologist V. April 1902, Dr. A. J. Grout listed as a new 

 combination Raphldostegtum admistum (Süll.) but this had already been 

 used by both Kindberg and Renaul d and Cardot. Further exami- 

 nation of the specimen collected irom peaty soil near swamp at Jamaica 

 shows it to be referable to Isopterygium Micans (Sw.). Moore.
