COUNTY LISTS OF MOSSES 269 



Hyjmum ripariuin L. ?/■' On a tree stump by the side of 

 a pond near Martinsell Hill, Marlborough, in fine fruit. — H. 

 achmciim group Kneijfii var. i:)olycarpon 131and. 8/'' In a very 

 wet place, semi- submerged, near Shalbourne, Hungerford. Mr. 

 J. A. Wheldon kindly sent me the following very interesting note 

 regarding this moss : "I think your plant comes without any 

 doubt under var. polycarjyon Bland, rather than under v. inter- 

 medium. The cells are short and often in the lower part very 

 short and parenchymatous, and the outline of the leaf is quite 

 that of V. polycarpon. In addition it shows the curious mortifica- 

 tion of the stem apices from wdiich issue slender surculi which 

 often occurs in this var. and are said to exist in Blandow's original 

 example. Renauld refers to frequent occurrence of this malfor- 

 mation or ' sport ' in this var. in Mosses of France (Boulay), 

 The var. intermedium is usually more robust and with longer cells, 

 the long cells continuing down nearer to the base, and the forma 

 laxifolium shows this character and differs only in its distant 

 leaves. It is sometimes nearly as robust as forms of group 

 pseudofluitans whereas v. polycarpon is rarely a fine tall plant and 

 always somewhat slender. In Lancashire the var. intermedium is 

 a much commoner plant than is var. j^olyccupon — and I think that 

 is the case throughout England." — H. aduncum group pseudo- 

 fluitans var. paternmn forma gracilis Ren. 8." Growling in dense 

 masses in a pool on London Clay at Dod's Dowm Brickworks 

 {teste Wheldo7i). — H. exannulatum \d.v. pinnatum^owX. 8. Grow- 

 ing by the side of the above pool on London Clay at Dod's Down 

 Brickworks {teste Wheldon) ; this is the typical form of TI. exan- 

 imlatum (jximh. — H. cupressiforme var. ericetorum B. & S. 7," 8.'' 

 C.fr. among heather near London Ride, Savernake Forest ; also 

 c.fr. among heather near Bedwyn Brails Wood, scarcely so 

 pinnate as typical ericetorum but would distinctly come under this 

 var. {teste Knight). — H. cordifoliimi Hedw^ 8. C.fr. in a very 

 wet rushy place in Bedwyn Brails Wood ; I recorded this moss in 

 my paper on East Wiltshire Mosses above mentioned, and w^as 

 pleased to find that at the end of May capsules were produced 

 freely ; the setae are very long in this species. 



Hyloconiium spleiidens B. & S. 8. C.fr. among heather near 

 Bedwyn Brails Wood, a new locality for the fruit. 



Dorset Mosses (c. 9). 

 The following mosses were collected in the neighbourhood of 

 Swanage, Dorset, in February, 1916. Perhaps the most interest- 

 ing species in the short list is the rare Campylopus subulatus 

 which occurs in various places on the maritime sands of Studland 

 Bay near Swanage and is a new county record for Dorset. It was 

 found by Mr. H. N. Dixon in the New Forest in South Hampshire 

 (v.c. 11) some years ago and also grows in South Somerset 

 (v.c. 5) ; according to the Census Catalogue to gather it elsewhere 

 in England one would have to go as far north as v.c. 69 (West- 

 morland with North Lancashire) though it has been found in 

 several of the Welsh counties and occurs in five of the Scottish
