var. Hegii (later alluded to as Heegii), of Rircia sorocarpa. It is easily 

 distinjjfuished from typical R. sorocarpa by the presence of very large 

 thill-walled papilh\3 on the apper surface of the frond. 



The author then goes on to explain the mistake which caused E. 

 Levier to describe E. pseudopapillosa as monijucious, and he proves that 

 (1) R. pseudopapillosa is really a composite species, the description 

 having been partially compiled from specimens of R. sorocarpa var. 

 Beet/ii ; (2) R. pseudopapillosa is not mon(jecious, but probably difx'cious, 

 though the fructification is as yet unknown. The only known locality 

 for the species is now Rothenhof, near Stein. The author questions 

 whether R. pseudopapillosa can still retain its specific status, but for 

 lack of final proof he leaves the question open. 



European Hepatics.* — K. Miiller publishes another instalment of 

 his monograph of European hepatics in Rabenhorst's Kryptogamen-flora, 

 bringing to an end his treatment of the difficult genus CephaJoziella, 

 which comprises 23 species grouped under 3 subgenera — Schizophyllum 

 (3 species), Eucephaloziella (18), Prionolohus (7). A detailed description 

 of the structural characteristics of each species is given, illustrated by 

 figures. Critical notes, keys, tables, and other aids to the discrimination 

 of the species are supplied. 



Gymnocolea acutiloba in Britain.j — D. A. Jones describes the 

 characteristic structure of Gymnocolea acutiloba K. MiilL, a hepatic 

 recorded from Xorway, Tyrol, and Asia Minor, and now found to occur 

 near Harlech in North Wales. The specimens were submitted to 

 Kaalaas, author of the species, Schiffner, and other authorities. Some 

 critical remarks on allied species are added. 



Mosses of South Italy. | — G. Zodda publishes a bryogeographic 

 study of the province of Basilicata in southern Italy, and a catalogue 

 of all the Bryophyta known to occur in the province. The principal 

 chapters treat of the geographic conditions ; excursions afield (with 

 notes on the local distribution of the species, on moss associations and 

 habitats, etc.) ; the species considered in relation to altitude and in 

 relation to their habitats ; and to the chemical nature of the soil. 



North American Sphagnum. § — A. Le Roy Andrews publishes a 

 fourth note on Xorth American Sphagnum, and discusses the section 

 McUaco sphagnum, with its two species — S. compact um and S. strictum. 

 He treats of the characteristic structure of the group and the differences 

 between the two species, adding critical notes on synonyms, published 

 specimens, distribution, etc. 



Fontinalis in North America. ||— (I. E. Nichols, in publishing 

 notes on Connecticut mosses, treats of Sphagnum, Fontincdis, and a few 

 other genera. He calls attention to the polymorphic character of the 

 species of Fontinalis, and to the marked structural variations which
