established itself in Herefordshire ; still less in the position in which it proves to 

 have done so, namely in the Lord's Wood of the Great Doward Hill. Here this 

 plant occupies some square yards of ground ; fruiting after its manner with capsules 

 by the hundreds and the thousands, and by this mark at once declaring itself 

 distinct from the other Campi/lopodes which are so shy in fruiting. 



Still in the same alliance, I have to announce 



92. Archidium phaSCOid.es, Brid. ; a little Moss which has puzzled 

 systematisers to determine its right position. It has no very near relatives in 

 Europe, though many in other quarters of the globe : and it seems best placed 

 under the Dicranal alliance, though among its imperfectly developed members. It 

 is itself scattered in fair abundance through middle and south Europe, becoming 

 rarer northwards. It is known in Britain from Cornwall to Aberdeen ; but had 

 been searched for in Herefordshire in vain, until thisSpring, when it was discovered 

 clothing a barren bank overhanging the Monnow valley in the p.arish of Llan- 

 rothal, D. 1. 



We now pass to the large family of Screw Mosses, of which we have more 

 than one new member to introduce to our lists. 



148. Barbula rigida, Schultz. The story of the discovery of this 

 Moss in Herefordshire shows that your lists might well be fuller than they are, 

 wore your observer a more knowing man behind a sharper pair of eyes. It was 

 pointed out to me by Mr. Boswell in a small tuft of B. ambigua which I had 

 gathered on Shucknell Hill, D. 6. Truly these little plants require what Sohimper 

 calls an " oculatissimus vir, a worthy man with an eye in his head," to detect 

 them ! The present species may, it is likely, be found in other stations, though it 

 can hardly be general, in Herefordshire, since its occurrence is improbable upon 

 any form of sandstone. 



The same locality has given us another member of this group. 



151. Barbula cavifolia, Schpr. This Moss, like the last, is a lover 

 of oolite and limestone clays, being on such soils common ; but it will no doubt, 

 for that very reason, remain a rarity in Herefordshire. It is a doubtful member 

 of the Barhxda family, and has been bandied about between this genus and Poitia, 

 to which it is now again relegated. I found it in small quantity at Shucknell 

 Hill during the present year ; it also occurs on the borders of Dean Forest, on 

 the Silverstone Farm in Hope Mansel parish, where I found it some years ago, 

 but supposed at the time that the station lay in Gloucestershire. 



Yet another fresh Scrciv Moss to be credited to Herefordshire is 



167. Barbula Hornschuchiana, Schultz. This is seemingly a far 

 scarcer plant everywhere. But it is not so particular in its habitats ; inhabiting 

 sandstone, clay, or limestone banks ; and it is likely to prove far more widely 

 distributed in Herefordshire. At present it has been found on a sandstone lane 

 bank in the parish of Llangarren, D. 1 ; on a turf wall on the limestone of the 

 Great Doward, and in a marly railway cutting at Fawley Station, in D. 2. The 

 Llangarren specimens were with fruit. 



The county of Hereford is thus well represented in the Screio Mosses ; 24 out 

 of the 35 species inhabiting Britain liavin,' now been detected within its limits.
