64 MOSSES. 



it as growing on scattered tufts on the walls of Jeru- 

 salem. 



The Weissia family have an oval erect urn, a lid with 

 a sloping beak, and a simple fringe of sixteen teeth. 

 They are small, with leaves in eight rows, and the stems 

 grow in clusters. 



Upon hedge banks all about in Swaledale we found 

 large patches of fine, close, fresh green moss. A plant 

 which we examined with a pocket lens, showed its leaves 

 turned in at the edge, the lower ones lance-shaped, the 

 upper narrower ; the little oval urn was brown and 

 shrivelled, for its fruit had been ripe two months before. 

 This was the green tufted Weissia (W. controversa, Plate 

 VI, Jig. 1). A species with taller stems and crisped leaves 

 proved to be the Bent-leaved Weissia (W. cirrhata, Plate 

 V., Jig. 2); and one with the edges plain was the Curly- 

 leaved (W. crispula). 



The Whorled Weissia (W. verticillata) grows on drip- 

 ping rocks ; we found it afterwards half encrusted with 

 lime. It is a larger species, growing in a thick cluster, 

 and with foliage of a vivid green. 



Some plants of the Bristle-leaved Weissia (Brachyodus 

 trichodes) were sent us from Castle Howard, they are as 

 small as those of the Earth mosses, and even more deli- 

 cate in structure, Don's Bristle mosses, (Anodus donianus, 

 Plate VI, Jig. 3) is the first member of the Bristle 

 moss group, the characteristics of which are a wide- 

 mouthed roundish urn, a large beaked lid, a small veil, 

 single fringe, and bristle-shaped leaves. Don's Bristle 

 moss vies with the Bristle-leaved Weissia in minuteness ; 

 it differs from all the other Bristle Mosses in having no
