Hedwigia ciliata Ehrh. l-\ Sarsen stones near Aldbourne ;

Phascwn Floerkeanum Web. & Mohr. 8'''. Common in a 

 chalky field at Northhill Barn, near Marten. 



Pottia recta Mitt. 8". Chalky field at Northhill Barn, near

P. minutula Fiirnr. 7, 8. Abundant in a chalky field at 

 Northhill Barn, near Marten. 



Tortula mutica hindh. 8. On a tree in the village of Burbage, 

 near Savernake ; it grows at the base of the trunk ; higher up the

T. laevijpila var. Icevipilceformis Limpr. 7*. On Elder, 

 Beckhampton, about seven miles west of Marlborough; c.fr. 

 Well marked and with the foliose gemmae {Dixon). 



T. intermedia Berk. 1^^\ 8. On a sarsen stone near Marl- 

 borough (H. N. Dixon) ; a form occurred on a roof at Shalbourne, 

 near Great Bewyn, v.c. 8, which Mr. Dixon considered showed an 

 approach to the South European arboreal moss, Tortula pulvinata 

 Jur. He wrote concerning it : "I have heard from Mr. W. E. 

 Nicholson about the Tortula : he finds the plant an abnormal one, 

 and while the weaker leaves show a nerve section very much like 

 T. ]julvinata, he thinks they do not quite agree, and as the better 

 developed ones distinctly approach T. iyitermedia Berk, in the 

 nerve structure, though not quite so fully developed in the stereid 

 band, he thinks it should be referred there, and I think that is the 

 correct view."
