YORKSHIRE NATURALISTS AT ROBIN HOOD'S BAY. 23 1 



Habenaria bifolia. Bromus mollis. 



Epipactis palustris. Melica uniflora. 



Luxula sylvatica. Anthoxanthum odoratuin. 



Scirpus pauciflorus. Alopecurus geniculatus. 



Eriophorum vaginatum. Polystichum angulare. 



Carex remota and C. glauca. Polypodium vulgare. 



Some good specimens of the rare Cornus suecica were brought to the 

 meeting, which had been gathered on the moors at Cross Cliff, where 

 it is still abundant. This locality is about ten miles or more west of 

 Robin Hood's Bay, and is the most southern station for this arctic 

 plant in the British Isles. 



With regard to the Cryptogamia, Mr. Slater remarked that in 

 open situations, at a low elevation, the sunny dry weather scorches 

 up the more delicate cryptogams at this season, and many of them 

 can only be got in good condition during the spring and autumnal 

 months. The searchers in this section confined themselves to the 

 moist shady places in Howdale Beck, where the stream had cut its 

 way in the softer parts into deepish gorges. The following were met 

 with, which are not included in the list given in The Naturalist, 

 August 1888. 



Of Mosses were noted the following : — Dicranella varia Hedw. (in 

 old fruit), Ceratodon purpureus L. (in old fruit), Grimmia apocarpa L., 

 Grimmia schultzii Brid. = G. decipiens Lind. (this moss is recorded 

 from Robin Hood's Bay, gathered by Mr. Massee, in Part n of 

 Braithwaite's ' British Moss Flora '), Funaria hygrometrica L. (growing 

 abundantly on damp banks, in fine fruit), Fissidens taxifolius , L., 

 Plagiothecium undulatum L., P. denticulatum L. (a large form of this 

 moss was got in fine fruit much resembling P. sylvaticum ; it proved, 

 however, to be monoecious, the latter being dioecious, and not fruiting 

 until September), P. borrerianum Spruce (a fine form of this was 

 gathered, having very distinct short two-nerved leaves ; it had no 

 fruit, but in the axils of the leaves some bundles of gemmiparous 

 buds, by which the plant increases, as it is rarely found in fruit), 

 Rhynchostegium ruscifolium Veck, Hypnum palustre L. (the normal 

 form, also a large variety, having a strong single nerve reaching to 

 the middle of the leaves, which are also very secund), Bryum 

 capillars L. (in good fruit), Atrichum undulatum L. (with male 

 flowers). 



Of Hepaticae were detected — Cephalozia lammersiana Hueb. 

 (some dense-growing patches seen, having the segments of the leaves 

 unusually broad), Lophocolea cuspidata Limp, (in good fruit), 

 Scapania purpurascens Hook., Diplophyllum albicans L., Nardia 

 obovata Nees (some fine tufts met with, having young perianths on 

 them), Jungermania inflata Huds., and Pellia calycina Tayl. 



Aug. 1889.
