BOTANICAL EXCHANGE CLUB REPORT 327 



5-10 ctm. alta. Radicibus plurimis ad perpendiculum directis. 

 Cormo robusto, vaginis veturum foliorum dense cooperto. Folia 

 capillis longis albis hirtis densius vestita, praecipue petiolis. 

 Pedunculi breviores 3-5 ctm. Flores magni 2-5-2-8 ctm. 



" Near to B. valdepuhens Jord., of which it may be a dune- 

 form. Differs from B. bidbosus by its shorter growth and larger 

 flowers, its corm being densely clothed, and the leaves and 

 petioles being covered with long shaggy hairs. Sand dunes, St. 

 Ouen's Bay, Jersey, April, 1910." 



" Crat^gus Oxyacantha L. var. quercifolia Druce. Styl. i. 

 Calyces et pedunculi densius hirsuti ; foliis pallide virentibus 

 pubescentibus, in textura molliter — papyraceis, rhomboidis ad 

 bases late cuneatis ; foliorum marginibus in 5-7 segmentis in- 

 equaliter divisis, segmentis obscure et diverse crenatis ; ramis 

 floriferis contortis. Kirkcudbright." 



" Galium palustre L. var. serrulatum. Planta 45 ctm. alta ; 

 caule glabro. Folia parva in verticillis 5-6 foliorum ipsa anguste 

 lanceolata 5-8 mm., margine minute serrulata. Ramis floriferis 

 divaricatis. Near Sandford Mill, Berks, 1910." 



" Galium palustre L. forma angustifolia. Planta 20-30 ctm. 

 alta, caule tenuo, verticillis 5 vel 6 foliorum. Folia parva 5-8 mm. 

 longa 1-2 mm. lata, anguste lanceolata, glabra, margine Integra. 

 Rami floriferi diffusi divergentes. Near Marsh Gibbon, Bucks, 1910." 



With regard to the first of these, it is to be noted that Mr. 

 Marshall, on p. 538 of the Report, has the following note : — " The 

 material sent to me is too young to base any valid opinion upon ; 

 as far as I can judge, it is nothing but a state due to the situation. 

 Cultivation may prove the characters to be permanent. Rev. 

 H. E. Fox has sent specimens to the Watson Exchange Club 

 which appear to be just the same thing." 



Viola Biviniana Reichenb. var. diversa Gregory is indicated 

 but not clearly defined. Mr. Druce's portion of the Report also 

 contains bibliographical and biographical notices. 



The second portion, edited by Dr. Moss, is more definitely 

 concerned with the actual work of the Club, and contains many 

 notes of considerable interest, to which most of our British 

 botanists contribute. It also afl'ords the usual evidence of differ- 

 ences of opinion between capable botanists — sometimes {e.g. the 

 Barbarea from a brickyard (p. 539)) the result of "poor material" 

 hardly worth wasting time upon. We hope later to quote 

 some of the more interesting notes at length ; meanwhile we see 

 that Campanula persicifolia, the occurrence of which in very 

 small quantity in Gloucestershire was recorded some time since — 

 we observe that Mr. Druce says that " the locality is destroyed," but 

 that can hardly l)e — has made its appearance on a common near 

 Newbury, where Eupliorbia Cyparissias is also found, although 

 not with the Gampaniila ; that Jwicus tenitis has occurred in 

 Ayrsliire (see Journ. Bot. 1910, 259); that Spartina Townscndi 

 has recently been found on the French coast opposite Hampshire; 

 that Hierochloe borealis has occurred on the Kirkcudbrightshire 

 coast, in very small quantity ; and that Glaytonia pcrfoliata is
