PLANTS ON A BRADFORD WASTE HEAP. 



JOHN CRYER. 



Last year on a waste heap near Bradford a very interesting 

 series of plants was found growing luxuriantly. Most were 

 casuals ; a few were aliens. Amongst the former were Lepi- 

 ditim niderale L., Coronopiis didymtis Sm., Medicago denticulata 

 Willd., Medicago arahica Huds., Carum carvi L., Solanum 

 nigrum L., Marnihiiim vidgare, L. Of the last there were two 

 very fine plants, the principal shoot of each being two feet in 

 height, and the lower lateral branches sixteen inches in length. 



The Chenopods were well represented. In addition to 

 Chenopodiiim album L. and its varieties, C. viride L. and C. 

 pagamim Reichb., there were fine examples of C. opulifolium 

 Schrad, C. serotinum L., C. Vidvaria L., and two large beds of 

 C. murale L. The grasses were also well represented by 

 Panicum crus-galli T.., Setaria viridis Beauv., Setaria glauca 

 Beauv., Polypogon monspeliensis Desf. (in abundance), Gas- 

 tridiiim lendigerum Beauv., Festuca myuros L. (in abundance), 

 and Bromus madritensis L. 



Amongst the aliens were Carthamus tinctorius L., with its 

 large head of richly coloured orange-red flowers, and Trigonella 

 caerulea Ser., with its rich, silky lilac flowers. Three alien 

 grasses were Bromus tectorum L., Bromus unioloides H. B. and 

 K., and Deyeuxia forsthii Kunth. = Agrostis retro-pacta 

 Willd. Agrostis retro-pacta Willd. is not recorded in Dunn's 

 ' Alien Flora of Britain,' nor in Druce's ' List of British Plants.' 



Mr. A. Bay don Jackson, Secretary of the Linnean Society, 

 to whom I sent a specimen, writes : — ' An interesting find, as it 

 has not been noted as an alien before in England, so far as I 

 am aware.' 



It is, I understand, a common Australian grass, and must 

 have been brought over with wool. 



Erratum. — On page 253 of the July issue omit the 4th line from the 

 bottom and read : — ' This explains the scar of leaf (F^) encircling,' etc. 



A ' fine specimen of the bony sunfish ' was caught at Filey on July 

 2 1 St. It measured ' about 2 ft. 6 in. in length, and was almost as much 

 across.' 



We are pleased to find that Dr. A. R'. Dwerryhouse, F.G.S., the Presi- 

 dent of the Geological Section of the Yorkshire Naturalists' Union, has 

 been appointed lecturer in geology at the Queen's University, Belfast. 

 At the same time we are sorry that this promotion means that Dr. Dwerry- 

 house leaves Yorkshire.
