YORKSHIRE NATURALISTS AT SEDBERGH. 



281 



These are : Saxifraga aizoides (gill between Winder and Crook 

 Fells — J. Backhouse, jun.); Galium boreale (near the Lune bank); 

 Hieraciufn crocatum Fr. (banks at Howgill) ; Hieraciutn iimbellatutn L. 

 {Lune-side banks), and the little toad-flax (Linaria viscidd) already 

 alluded to, but this last is, properly regarded, adventive to the 

 district. The 'Rusty-back' fern {Ceferach officinariini) shown at the 

 meeting, was gathered by Mr. T. W. Edmondson on a farm-yard 

 wall near the railway viaduct between Sedbergh and Lowgill, to reach 

 which the Lune has to be crossed, so that was a few yards across 

 the boundary, and in Westmorland. At Cautley 'Spout' the 

 Film-fern {^Hymenophyllum uiiilaterale Willd.) was seen growing in 

 massed abundance (in shrivelled state) on rocks many yards away 

 from the much reduced stream at this time — evidence both of the 

 exceptional drought and the wide-spreading spray of the cascade 

 when in its normal volume. When in spate, the ' force ' must be 

 without a rival in Yorkshire for height and grandeur. 



With the assistance of the cryptogamic visitors, 89 Mosses, 

 2 \ Hepatics, and upwards of 50 Lichens were noticed — the majority, 

 of course, already on record, but the following are worth mention by 

 name as being hitherto unknown for the drainage district of the 

 Lune : Dichodotitium flavescens, Dicranum palustre^ Didymodon 

 ^yliiidricus Br., Grimmia trichophylla, G. commutata Hiibn. (G. 

 Stabler, ms.), Orthotrichtcm saxatile Brid.,and Plagiothecium sylvaticum. 

 Of these the Grimjnia commutata (Cautley) is not only new to the 

 West Riding, but has never been recorded before for any part of 

 Yorkshire. This is as yet, a name record only of Mr. Stabler's, set 

 down in manuscript, amongst the names of others got during the 

 excursion by him, but neither Mr. Slater nor Mr. West have seen 

 specimens. It may thus be held to require confirmation ; this taking 

 time, the result may not be stated here. Most of the other mosses 

 observed were species of wide distribution, in mountainous regions 

 especially, but mention may be made of some few of the rarities, 

 previously known for the Lune basin, a confirming record for which 

 can hardly be out of place : such were Gymnostomum commutatum 



Barbula curvirostris vdjr., Braith. Mon.), Trichostomum crispuluin 

 (M. B. Slater), Barbula revoluta, Orthotrichtwi rupestre^ Blindia acuta ^ 

 Bryum filiforme Dicks. { — B. Juiaceum), Mnium stellar Polytrichum 

 formosum, Hedwigia ciliata, Heterocladium hderopteru7?i, Neckera 

 pufnila^ and Hypnum eugyrium. Among Hepatics the best species 

 gathered were Lejeunea calcarea Lib. (in fruit), Madotheca Icevigata, 

 Jungermania barbata^J. riparia Tayl., J. bantrimsis Hook., Nardia 

 emarginata, Trichocolea tomentdla, Mylia taylori, Juiiger7nania 

 cordifolia^ and Mctzgeria conjugata.
