508 TYPHACEAE 



First record of the aggregate sjjecies. .S. ramosum. Greater Burweed, 



Dr. Noehden, Maror's Agr. Berks, 1809. The restricted species is 



recorded here for the first time. 



The true S. erectum (S. ramosum, Huds.) is found in all the districts. 



I have not kept a complete list of localities, but have noted it at 



Wytham, Appleton, Lechlade, &c. in the Isis district ; at Abingdon, 



Kennington, Appleford, Radley, Marcham, Hagborne, &c. in the Ock 



district ; at Bradfield and Tidmarsh in the Pang district ; at Theale, 



&c. in the Kennet district ; and at ^Yinkfield, Wellington, Windsor, 



&c. in the Loddon district. 



S. erectum is recorded for all the boi-dering counties. 



S. neglectum, Beeby in Journ. Bot. xxiii. (1885) 26. 

 S. erection, var. neglectum, Richt. PI. Europeae, 10 (1890). 

 This plant is found in similar situations to the last, with which 

 I have seen it growing. 



First found in Berkshire by the author in 1885 and recorded in the 

 Flora of Orfordshire, 316, 1886. I have kept no exhaustive list of its 

 localities, but I have noticed it in all the districts. 



1. Isis. Cumnor. Buscot Park. Longworth. Wytham Wood. 



2. Ock. South Hinksey. Abingdon. Radley. In ditches on 



Abingdon Racecourse, very fine. By the canal at Uffington. 

 Wantage, Cothill, &c. 



3. Pang. Moulsford. 



4. Kennet. Sandleford, &c, 



5. Loddon. Hurst. Winkfield. Wokingham. Wargrave. Vir- 



ginia Water. Sandhurst, &c. 

 S. neglectum is found in all the bordering counties. 



S. simplex, Huds. Fl. Angl. ed. 2, 401 (1778). Bur-reed.

 First record. Sonning, Mr. S. Budge in Herb. Brit. Mus. 1800. S. simplex, 

 Dr. Noehden in Maiw's Agr. Berks, 1809. 



In our rivers and canals it is often barren. Occasionallj'" the form 

 v/ith floating leaves and stems bears flowers, and naturally the base of 

 the floating leaf is not so distinctly triangular ; this I have seen at Ferry 

 Hinksey, &c. ; it is the var. fluitans, Gren. & Godr. Fl. Fr. iii. 337. 



Sparganium simplex is found in all the bordering counties.
