ALOPECURUS 557 



Jotim. Bot. (1875) 1-5, t. 157 (not very good). Nyman, 790. Fl. Oxf. 332-3. 

 Casual. Cultivated fields. Eare, and not permanent. A. Jvine- August. 

 First recorded by Mr. F. Tufnail, 1883, in Rep. of Bot. Bee. Club. 



5. Loddon. Sonning, in sandy field with clover, &c., Tufnail. See 

 Dr. F. A. Lees in Bei). of Bot. Bee. Club (188$), 52. I found it in a wild-looking 

 spot, on a grassy bank in the heathy country near Wellington College, 

 perhaps introduced with pheasant food, but I saw no Buckwheat near. It 

 also was seen in a clover field near Clewer.

Dr. Noehden, Mavor's Agr. Berks, 1809. 

 This is the troublesome weed, Mr. Tufnail tells me, known as the 

 Black Switch or Black Grass, which is common in all the bordering 

 counties.

A. paludosus, Beauv. ex Mert. et Koch in Roehl. Deutsch. Fl. i. 481. 

 Top. Bot. 474. Syme, E. B. xi. 23, t. 1700. Nyman, 794. Fl. Oxf. 334. 

 Paludal. Native. Margins of ponds. Very local and confined to a few 

 localities on the London Clay. It prefers wetter situations than 

 the next species, with which it is sometimes confounded. P. 

 June-August. 

 First record. A. fulvus, Mr. H. C. Watson in Britten's Contr. 1871. 



5. Loddon. Brickfield by Embrook Mill near Wokingham, Watson. 

 Seen there, but very sparingly, in 1889 by the Bev. V. C. Craivley ; 

 it was more plentiful in 1892 when I sent specimens to the Bot. 

 Exch. Club ; see Bep. p. 390. I was very glad to find this local 

 species in great abundance and luxuriance in two ponds, nearly 

 opposite Shottesbrooke Church (not the pond which is close to 

 the church, but the one nearer to Waltham), on the road to 

 Twyford. Here it was a conspicuous object from its bright 

 orange- scarlet anthers and glaucous foliage. It also occurs in 

 a marshy field near Twyford and in a marsh near Ruscombe.
