342 SUMMARY OF CURRENT RESEARCHES RELATING TO 



orbicularis Bruch and Pottia bryoides Mitt, in the Silverdale district, as 

 new additions to the West Lancashire flora. 



Yorkshire Mosses.* — C. A. Cheetharn, in his bryological contribution 

 to the forty-eighth annual report of the Yorkshire Naturalists" Union, 

 gives some notes on the more interesting species of mosses and hepatics 

 collected in the county during 1909. 



George Stabler (1839-1910).t— A brief obituary notice of George 

 Stabler of Levens, Westmorland, is given. Born at Welburn, near 

 YTalton, he became schoolmaster at Levens forty years ago, and is well 

 known as a collector of rare Bryophytes. He became blind a few years 

 before his death. 



New Hybrid Moss in Sussex.}— W. E. Nicholson describes a curious 

 moss which he found fruiting on the coast of Sussex, namely, Tricho- 

 stomum fiavovirens fruiting with subcleistocarpous or imperfectly 

 peristomate capsules. Intermixed in the tuft were several plants of 

 Weisia crispa ; and Nicholson is of opinion that the capsules were the 

 result of hybridisation between the two species. He carefully describes 

 the sporogonia, and points out that this is the third example from the 

 Sussex downs, where the male plant of Weisia crispa has formed hybrid 

 capsules with other mosses. In the other instances the female plants 

 were Weisia crispata and W. microstoma. 



Mosses found in Conservatories^— E. G. Britton gives an account 

 of a rare moss in the conservatories of the New York Botanical Garden, 

 namely, a Splachnobryum, probably the same as the species described by 

 H. N. Dixon in 1907. Three times previously have members of the 

 same genus been found in greenhouses. The New York specimen was 

 in fruit, and was growing on a pot of tropical orchids. In a cool palm- 

 house was a fine growth of Hypopterygium, and in other houses were 

 found the commoner species Catharinea angustata, Physcomitrium 

 turbiiiatum, L&ptobryum pyriforme, and the ubiquitous Marchantia. 



New European Frullania.fl — V. Schiffner gives a careful description 

 and figures of FruUaiiia cleistostoma, a new species discovered by him on 

 walls at Meran, in Tirol, in 1899, and found again in the same neigh- 

 bourhood last year by W. Wollny. It belongs to the subgenus 

 Trachycolea, and is remarkable as being autoicous. It is allied to 

 Frullania cesatiana, found in the same district. The principal distinc- 

 tive character of F. cleistostoma is the mouth of the perianth, which is 

 blocked by a lining of clavate papilla?, which can be seen under the 

 Microscope by transmitted light, and do not necessitate the cutting of 

 sections. 



New Species of Anastrophyllum.lf — Y. Schiffner gives a descriptive 

 account with figures of Anastrophyllum Joerye/isenii, a new species dis- 

 covered by E. Jorgensen in Eikef jord, in Western Norway. It is related 

 to A. Donianum, with which it is contrasted by the author.
