Barbula cylindrica, Wils. MSS. Common on trees and wood 

 subject to be inundated by the water ; in fruit on a tree 

 near Writtle Park. I can scarcely believe this to be a variety 

 of Cinclidotus riparius, as I have carefully sought for that 

 species around where the Barbula cylindrica grows, and in 

 water adjoining, but in vain. Mr. Thwaites also, makes the 

 same remark respecting the Bristol B. cylindrica. 



latifolia, Wils. MSS. In the same situations as the last, but 



not so common, and in spots that are more frequently sub- 

 mersed. 



Polytrichum undulatmn. 



piliferum. Abundant on Galleywood Common. 



juniper mum. Ditto and elsewhere. 



commune. 



formosum. On a piece of common at Little Baddow. 



aloides. Galleywood Common. 



nanum. Ditto. This, now considered a variety of P. aloides, 



has, when I have gathered it, grown in patches distinct 

 from the latter, and preserved its character of rounded cap- 

 sule unaltered. 



Funaria hygrometrica. 

 Orthotrichum affine. 



/3. pumilum. 



diaphanum. Pretty common. 



striatum. Trunks of trees, generally in woods, mostly in 



small patches. 



crispum. Ditto. 



Bryum androgynum. Barren or gemmiferous state ; frequent in the 

 neighbourhood of Little Baddow. I gathered a few immature 

 capsules on the 16th of May last. Mr. Mitten (Phytol. i. 616), 

 mentions finding the fiuit not quite mature in the early part 

 of April, so that his plants seem rather forwarder than mine. 

 The time of fruiting is not mentioned in ' English Flora.' 



palustre. In fruit in a wood near Galleywood Common, and 



sparingly upon Woodham Walter Common. 



carneum. By the side of a pond near Barn's mill, and by 



the side of the road between Chelmsford and Roxwell, along 

 with Dicranum varium, which it has always accompanied 

 when I have gathered it. 



argenteum. Mostly fruits upon gravel- walks, in gardens. 



capillare. Pretty common.
