BRYOLOGICAL NOTES. 



By E. M. Holmes. 



The occurrence of the following new species in localities other 

 than those which have already been published may, perhaps, be 

 in t cresting to British bryologists : — 



Baibula sinuosa. — On a stone in a hedgebank in a limestone 

 district, near Totnes, Devon ; Leigh Woods, near Clifton, Bristol, 

 on limestone ; Buckingham, on the exposed roots of trees, and at 

 the base of their trunks, growing with Tortula latifolia, on oolitic 

 soil ; Hanwell, near Banbury, on a damp oolitic limestone wall ; 

 Oxford, on a tree stump by the side of the canal ; Dunton Green, 

 in a wood on the chalk. 



In the moist state it occurs generally in small dense tufts 

 which resemble T. vinealis in appearance, but have the peculiar 

 colour of Grimmia pulvinata. When growing in dry places, or on 

 the tops of limestone walls, as at Plymouth, it is of a somewhat 

 brownish-green colour. When dry it resembles Tortula nitida, but 

 the nerve is not glossy, and each stem appears separated from its 

 fellow, although united below by tomentum. 



Under the microscope it is readily known by the fragile tips of 

 the leaves, of which the young and more perfect ones are seen to 

 have two or three irregular teeth at the apex. 



Dicranum montanum.— Abbey Wood, Kent. On the stumps 

 of chestnut trees (Casianea vesca) which have been cut down, but 

 which have sent out a new growth ; the soil is sandy. It grows 

 intermixed with Tetraphis pellucida, and occurs in densely compacted 

 tufts of a deep green colour, in appearance resembling Weissia 

 cirrhata, but with the leaves rather more erect. It also resembles 

 that plant when dry. Under the microscope, however, it is readily 

 distinguished from it by the margins being serrated as well as the 

 back of the nerve towards the apex of the leaf. The leaves are 

 also distinctly papillose. 



Stereodon canariense.— Near Buxton (Mr. E. George). The 

 specimen I have received is a dense flat tuft in which the stems 

 are about ^ inch long, and erect ; it has a more rigid appearance 

 than //. cupressiforme. The district in which it occurs is lime- 

 stone. 



Fottia cavifolia. — I have only seen this plant growing on oolitic 

 soil, and believe it to be confined to that soil and magnesian lime- 

 stone. On the oolite it is extremely abundant, the mud-capped 

 walls being brown with its capsules. 



Amblystegium confexvoides.— On limestone rocks, in Leigh 

 Woods, near Clifton, Bristol. In fruit August, 1873. It grows 

 in thinner tufts than Hypnum sevens, and is of a darker, almost 

 blackish- green colour in old specimens, and is in young fruit in 

 July, and the beginning of August.
