322 SUMMARY OF CURRENT RESEARCHES RELATING TO 



species and eight varieties as valid and, having arranged them in groups, 

 describes them in detail, giving the full distribution in Italy and adding 

 critical notes on the allied species that occur in the rest of Europe. An 

 analytical key and an index are supplied. 



Papillate Hepatics.* — I. Douin remarks upon the rarity of papilla 

 in hepatics, and distinguishes the different forms of papilla? met with 

 in the group. He discusses the specific value of three species of C&pha- 

 lozia with papillate leaves, and proposes a scheme of classification for 

 them, and adds critical notes upon some other species of Gephalozia and 

 Lepidozia, and upon Jungermannia exsectaformis as compared with 

 J. exsecta. 



The same author f gives a list of six mosses and nine hepatics hastily 

 gathered between the gushes of the intermittent spring of Fontestorbes 

 near Belesta (Ariege) on the north side of the Pyrenees. 



Fossombronia.J— L. Corbiere describes a new species, Fossombronia 

 Orozalsii, gathered by A. Crozals in the south of France, and distin- 

 guishes it from F. angulosa and F. Dumortieri to which it is allied in 

 the markings of its spores. And he adds some notes upon the dis- 

 tribution of the genus in France. 



German Hepatics and Sphagna. § — C. Warnstorf completes his 

 account of the hepatics and Sphagnacese of Mark Brandenburg, the 

 whole cryptogamic flora of which is in course of publication by several 

 specialists. He describes the species carefully and amply, distinguishes 

 the varieties, and adds critical notes. To the tribes and genera he 

 appends analytical keys. The numerous figures are a valuable feature 

 of the work. 



Italian Hepatics. || — E. Barsali publishes a list of the hepatics that 

 are found on Monte Pisano and in the neighbourhood of Pisa, giving 

 localities and the principal synonyms. There are 67 species in all, 

 eleven of which are new to the district. The introduction contains an 

 account of the geographical distribution in the district and of the 

 various substrata selected by several groups of species. 



C. Massalongo 1[ transcribes the descriptions of two European species 

 of Scapania which, as he has recently ascertained, occur also in Italy. 

 They had previously been found only in Scandinavia and the eastern 

 Alps. 



American Hepatics.** — C. C. Haynes records the discovery near 

 Prospect Harbour, Maine, of Gephalozia Francisci Dum., for the first 

 time in America. Originally described from Norfolk by Hooker, the 

 species is rare in Europe. At the same locality in Maine were found a 

 few other rare hepatics. 



Lejeunea in North America.ft — W. C. Barbour describes the ten 

 species of this genus that occur in the North-eastern United States,
