FORTY-THIRD ANNUAL REPORT, FOR I904. I7 



and successful one with mosses and hepatics. In the " Naturalist " 

 several valuable papers, beautifully illustrated, have appeared 

 on "The Biology of some Frondose Hepatics," by Mr. F. 

 Cavers, D.Sc, who, for his research in this department, has 

 been awarded the valuable degree of Doctor of Science of 

 London University. 



Papers have also appeared in the "Naturalist" by myself, 

 on the mosses and hepatics observed during the meetings of the 

 Y.N.U. at Harwood Dale, at Hebden Bridge, and at Buckden. 

 The most noteworthy plants recorded during the year are : — 



Scapania aspeva, mentioned as frequent on the limestone 

 rocks of West Yorkshire by Mr. W. West, and this fact 

 was confirmed by my own observations on the limestone 

 rocks in the neighbourhood of: Buckden. Scapania suhalpina, 

 recorded as frequent in Hebden Valley. Saccogyna Viticnlosa 

 also occurs here, as does the moss Weisia cvispata. At Harwood 

 Dale were found the beautiful Cephalozia ciivvifolia and the minute 

 Cephalozia lunulaefolia. At Buckden are Ditricimm tortile, new to 

 the West Riding, Seligevia tristicha, Bvachytheciiim salebrosum, and 

 many others mentioned in the October number of the 

 " Naturalist." A new variety of Kantia trichomanis on Buckden 

 Pike, the North Riding side, and on the moor above Deepdale 

 will be shortly described as var. aquatica, on the recommendation 

 of Drs. Arnell and Persson, of Sweden, and of Mr. Macvicar, 

 who call it a notable variety, deserving of such a name as the 

 above. Lepidozia trichoclados and Jungermania minuta grow in 

 association in a wood on Strensall Common. Campylopiis 

 atrovireus var. vinticiis grows on Skip worth Common, a great 

 extension of its southern range. Weisia calcarea var. muticnm 

 occurs sparingly in Jackdaw Crag Quarry, Tadcaster, and Nardia 

 minor in Hebden Valley.

 ports : — Since the last annual report was issued, the Myco- 

 logical Committee and their co-workers have been by no means 

 indifferent to their work. The three new things found at the 

 very successful Foray at Helmsley, were described in an
