610 SUMMARY OF CURRENT RESEARCHES RELATING TO 



cladus aduncus var. Wheldoni, from the Southport sand dunes, was 

 recently described by Renauld, and differs in its markedly dimorphous 

 leaves from var. falcatus. Another new form from the same place is 

 D. aduncus var. falcatus f. littoralis Ren. It is the ordinary form of 

 the sea-shore. A puzzling specimen from near St. Anne's has been 

 referred by G. Roth to D. aduncus var. pseudo-Sendtneri. 



Lancashire Hepatics.* — W. Gr. Travis announces that he was 

 fortunate enough to rediscover the rare Petalophyllum Ralfsii among the 

 sandhills at Freshfield. Years ago it used to occur near Birkdale, but 

 the site is now built over. It is distinguished from all other British 

 hepatics by the delicate dorsal lamellae on its thallus. 



He also | records the finding of Lejeunea cavifolia in Skillaw Clough, 

 near Parbold, south Lancashire, where it was sparingly associated with 

 Metzgeria furcata and Neckera complanata on Permian limestone. 



Additions to the Manx Sphagna.^ — J. A. Wheldon records some 

 additions to the Sphagnaceae of the Isle of Man. The Census Catalogue 

 of British Mosses gives a complete record of the Manx moss-flora up to 

 1907. Nine species and five varieties of Sphagnum are there recorded. 

 But the island is really rich in these plants in its moorlands and bogs. 

 And Wheldon now furnishes a list containing twenty-one species and 

 nineteen varieties. It is expected that another ten or twelve species, 

 such as occur in Lancashire and Westmorland, will lie found upon 

 further search. 



Moss-flora of the Jura.§ — C. Meylan gives a list of species gathered 

 by him in the Jura during 11)08-9, namely twenty-three mosses, four 

 sphagna, nineteen hepatics. Eleven of them are new to the range. 

 Special notes are added to Brachythecium Geheebii and to Galypogeia, 

 the relationship of G. Neesiana to G. Tricliomanis being discussed, and 

 a key appended to facilitate the better discrimination of G. suecica, 

 G. Neesiana, G. Tricliomanis, and their varieties. 



Moss-flora of the Haute-Saone.|| — A. Coppey begins a series of 

 phytogeographic studies on the mosses of the Haute-Sadne. In the 

 present instalment he makes an introductory statement and defines the 

 object of his work ; provides a bibliography extending from 1845 to 

 1909, and briefly criticises its contents ; describes the general characters 

 of the region, and explains the method adopted ; and makes some general 

 remarks on ecology. His work is based on the Catalogue raisonne of 

 Renauld (1873 and 1883), with additions to and corrections of its deter- 

 minations and its notes on distribution. 



Spanish Bryophytes.1T — A. Casares Gil gives a list of ten hepatics 

 and nine mosses which are new to the Spanish flora. Among them is 

 a description of the new Scapania Casaresana Steph.
