YORKSHIRE NATURALISTS AT HARROGATE. 239 



On and about the cliffs on the north bank of the Nidd, between 

 'Eugene Aram's Cave' and Knaresborough, Viola hirta L., Patietaria 

 officinalis L., Asplenium ruta-muraria L., and A. trichomanes L., 

 all known to occur here, were gathered. As a fitting conclusion to 

 the work, and as a happy reminder of this very successful field-day, 

 the rarest plant met with, Sagina apdala L., was obtained on the 

 masonry-coping of a wall at Knaresborough Station as we waited for 

 the Harrogate train, being still another record for the Nidd drainage 

 district. 



Mr. Matthew B. Slater, F.L.S., of Malton, Cryptogamic Secre- 

 tary of the Section, reported as follows : — Of Mosses the only 

 Sphagnum seen was S. subsccundum Nees, wet place, Hookstone 

 Wood; Dicrandla hctcromalla Hedw., Hookstone Wood, tufts 

 coming into young fruit ; Dicranum scoparium L., Hookstone 

 Wood ; Eudadium veriirillatum L., a dwarf form growing abundantly 

 under the arches of the bridge at Plumpton Rocks ; it was without 

 fruit, but had female flowers; Encalypta streptocarpa Hedw., growing 

 in abundance in the joints of a wall by road-side near to Plumpton ; 

 sterile, however, and is very rarely found with fruit ; Webera nutans 

 Schreb., in old fruit on heathery banks in Hookstone Wood; 

 Polytrichum formosum Hedw., in similar ground with the Webera ; 

 Bryum pallens Swartz, by stream-side near Bleach Mills, Crimple 

 Valley ; Homalolherium sericeum Schpr., growing abundantly on 

 walls, sterile at this season; Brachythetium rutabidum L., on rocks by 

 stream in Crimple Valley; Plagiothedum denticulatum L. var. 

 aptychus Spruce, in old fruit; P. undulatum L., without fruit; 

 P. borrerianum Spruce, without fruit ; Hypnutn cupressiforme L., 

 without fruit; H. schreberi Ehrh. — all five gathered in shady places 

 in Hookstone Wood ; and Amblystegium fluviatile Swartz, gathered 

 from rocks by stream near Bleach Mills. Of Hepaticae were noted : 

 Mardiantia polymorpha L., Fegatella conica L., Pellia epiphylla L., 

 Scapania purpurascens Hook., male plants — all four from stones by 

 the stream in Crimple Valley; Lepidozia reptans L. with perianths, 

 on wet stones ; Cephalozia bicuspidata L., with perianths, on wet 

 stones, growing amongst Lepidozia ; Lophocolea heterophylla Schrad., 

 and Diplophyllum albicans L., with perianths, on heathery ground — 

 all in Hookstone Wood ; and Jungermania attenuata Lindenberg, 

 growing abundantly on Plumpton rocks. At this season, after such 

 prolonged dry weather, the cellular cryptogams were much dried up ; 

 some tufts were gathered in going along in their dry state, and have 

 been since moistened and examined. All the species obtained are 

 plants of fairly general distribution, but sufficient of the district was 

 seen to conclude that if the ground gone over was searched by 



Aug. 1889.
