494 SUMMARY OF CURRENT RESEARCHES RELATING TO 



Where iln archeironial inflorescence is carried down to the bottom of the 

 developing sac which is situated at right aDgles with the main axis of 

 the plant (Calypogeia type). 3. Where the archegonial inflorescence 

 I ii comes inclosed in a cylindric sac, a direct continuation of the axis of the 

 stem (Isotaxis type). These three types are connected by transitions. 

 Title-pages, preface, and index to the volume are supplied. 



New and Rare European Mosses.* — G. Roth gives descriptions and 

 drawings of some mosses which, for lack of authentic material, lie had 

 been compelled to omit from his book, Europiiische Laubmoose (1904-5). 

 Twelve species and varieties belonging to various genera are fully treated. 



British Bryophytes.t — W. Evans publishes a list of seventeen mosses 

 and two hepatics, collected by him on the Isle of May, and forming a 

 supplement to his previous list (1908). He found a curious Pottia, 

 which H. N. Dixon refers to P. asperula. 



Philonotis seriata with Fruit-! — E. A. Richards records the find- 

 ing of a fruit-bearing tuft of Philonotis seriata near Glen Isla and <!len 

 Doll, Forfarshire, at the end of July 1909, at an altitude of 3000 ft. 



Mosses of Spitzbergen.§ — H, N. Dixon gives a list of eight mosses 

 collected on Prince Charles Foreland, Spitzbergen, during W. S. Brace's 

 expedition in 1906-7. Their interest consists mainly in the fact that 

 three of them do not happen to occur in I. Hagen's account || of the 

 mosses gathered by the expedition. 



Muscinese of Bornholm.^l — W. Monkemeyer gives a list of the mosses 

 and hepatics of Bornholm, with a resume of the work of previous col- 

 lectors, and notes on the physical geography of the island. He adds 

 forty-five species and several varieties to the previous records of Jensen 

 and others, and brings the totals up to fourteen Sphagnacese, 288 mosses, 

 and fifty-eight hepatics. He figures a plant of Pohlia nutans with a 

 double capsule, the columella having proliferated, so that it terminates 

 in a subsidiary capsule. 



Moss-fiora of the Jura.**— L. Hillier has been studying the moss- 

 flora of the lower Jura on the French side, between the altitudes 800 ft. 

 and 2600 ft., his purpose being to do for the lower Jura what C. Meylan 

 is doing for the upper. His results are expressed in an enumeration of 

 mosses and hepatics, some of which have never previously been recorded 

 for the Jura ; some are new to, or rare in, the lower Jura, hut are known 

 or common in the upper Jura ; and some are common in the lower, but 

 rare or absent in the upper Jura. 



German Bryophytes.tt — V. Torka gives a list of the hepatics of the 

 north-east of the province of Posen. He and H. Miller collected forty- 

 one species. A larger number could not be expected in such flat country. 

 The most interesting record is Riciella Hubeneriana var. nutans, a new
