peat-mosses of Europe and North America recently issued by the 

 eminent European bryologist. Prof. S. O. Lindberg. It is m pamph- 

 let form, without illustrations, and the first 38 pages are devoted to 

 an introduction treating of the various portions of the plants, fol- 

 lowed by 88 pages containing descriptions of 21 species, to each of 

 which is added a full synonymy. The introduction and foot-notes 

 are in Swedish. I briefly note the following changes in nomencla- 

 ture where the names in italics have been reduced to synonyms : 

 ' 5. Austini, Sull.,=S. imbricatum, Hornsch. 



S. cymbifolium, Hedw.,=S. palustre, L. 



S. molluscum, Bruch„=S. tenellum, Ehrh. 



S. acuti/olium, Ehrh.,=S. nemoreum (Jung.) Scop. 



S. macrophyllum, Bernh., var. Floridanum, Aust.,=S. crib- 



rosum, 71. sp., Lindbg. 

 S. mendocinum, S. & L., is referred to S. cuspidatum,_Ehrh. 



Prof Lindberg has based his diagnosis of the nevv species, S. 

 cribrosiim, upon specimens I recently sent him, and which were col- 

 lected in Florida by the late C. F. Austin. It appears that the typi- 

 cal S. macrophyllum, Bernh., was not collected m Florida either by 

 T D Smith or C. F. Austin. Specimens recently communicated by 

 t' D Smith, collected in Eastern Florida and along the Caloosa 

 River all prove to be ^. cribrosum, Lindbg. No inflorescence has 

 been detected on any of the specimens thus far collected.
