Myurella apiculata, Hiib., distinguished from M.julacea 

 {Leskia moniliformis, Wils.) by its less imbricated leaves, 

 which terminate in a long apiculus. Ben Lawers, Perth- 

 shire. 



Brachythecium campestre, Br. On the ground, Mares- 

 iield, Sussex, Mr. Mitten. 



Brachythecium Mildeanum, Sch. This is the plant com- 

 monly known in Britain asHypnum salebrosum, occurring on 

 the sands at Southport, Fifeshire, Dublin, Cornwall. The 

 true H. salebrosum probably occurs on trees near Kirkham 

 Abbey, Yorkshire, Rd. Spruce; also in Sussex. 



Brachythecium rutabulum, var. plumulosum, Sch. Has 

 the aspect at first sight of a distinct species. Leaves usually 

 narrower than in Hypnum rutabulum, somewhat striate, 

 gradually tapering, acute, not acuminate ; and the plant has 

 a more glossy aspect. On the same stems, however, occur 

 leaves like those of typical rutabulum. Sands at South- 

 port. ' 



Eurhynchium Stokesii, Turn. {H. pralongum, var. Stoke- 

 sii, Wils. Bry. Brit.). Doubtless a common species, but 

 liable to be overlooked as H. pralongum. On the conti- 

 nent, on the other hand, where it is universally acknow- 

 ledged, H. Swartzii (a most distinct and beautiful spe- 

 cies, common throughout Britain) and prcdongum are 

 confounded, H. Swartzii being apparently much the more 

 common species there and usually distributed under the 

 name of H. pralongum. H. Stokesii is known on rocks 

 in England, Wales, and Ireland. H. pralongum has the 

 stem-leaves widely cordate below, lengthened out into 

 a long acumination, branch -leaves lanceolate; H. Stoke- 

 sii, stem-leaves more shortly acuminated, and the branch- 

 leaves ovate acuminate ; H. Swartzii, both stem- and 

 branch-leaves ovate, not acuminate. H. pralongum and 

 Stokesii have the capsule olive, suddenly bent at its junc- 

 tion with the setse; H. Sivartzii, capsule Yeddishhrown,
