Dryas octopetala, L. This plant has been found amongst the 

 Caernarvonshire hills, by one of the Snowdon guides, Williams 

 by name. Details relative to the station are given in the January 

 number of the ' Phytologist.' Por the specimen on the table we 

 are indebted to the courtesy of Mr. Irvine.* The species is dif- 

 fused throughout the Scotch Highlands, but southward has pre- 

 viously b;een noticed only in the two Yorkshire stations of Cronk- 

 ley Fell and Arncliffe Clouder. 



He exhibited specimens of Delphinium Consolida from various 

 Continental localities; of D. Ajacis, collected by Mr. Hort in 

 Cambridgeshire, and by Mr. Mudd and himself in Yorkshire ; of 

 D. orientate from a potato-field at Carlson Moor, near Thirsk ; 

 and of the Caernarvonshire Dryas. 



Mr. J. H. Davies read a notice from Dr. Carrington of the 

 occurrence of the following Mosses in the Isle of Man, which 

 were noticed in his list in the ' Phytologist :' — Orthotrichum 

 stramineum, 0. tenellum, Bryum pallescens, Grimmia patens (Glen 

 Laxey), Hypnum ochraceum (with fruit, near the water-wheel in 

 the Glen Laxey stream) ; and mentioned a new station for Schis- 

 tidium maritimum, observed by Dr. J. B. Wood, viz. rocks at the 

 Calf of Man. He also exhibited specimens of the following 

 Mosses : — 



Bryum cochlearifolium, Wils. MSS. This Moss was found by 

 Mr. J. P. Marrat, in 1855, in a quarry at Wavertree, near Liver- 

 pool. Mr. Wilson furnishes the following provisional diagnosis : 

 " Bryum atro-purpureo proximum, foliis patulis valde concavis 

 obtusis, apice incurvis, areolis laxioribus •/' and writes : '' The 

 fruit has not yet been found, and it still waits for establishment 

 as a genuine species. I have seen very little of it, but its very 

 concave leaves seem to separate it from any allied species.'^ 



Leptodon Smithii, Westmoreland. Found by Mr. Nowcll, in 

 1857, on trees in Borrowdale. This discovery extends consider- 

 ably the northern limit of the species in this country. 



Andrecea Grimsulana, Bryol. Eur., Aberdeenshire. Discovered 

 by Mr. Croall on Ben-na-rauic-dhui. Distinguished from A. ru- 

 pestris by its larger size, branched habit, and broader leaves. , 

 Near tq Britain ; but perhaps not a distinct species.
