524 CYPEEACEAE 



CYPEKACEAE, J. St. Hil. Exp. Earn. i. 62 (1805). 



[Cyperus fuscus, Linn. Sp. PI. 46 (1753). Syme, x. 41, t. 1577. 



Is found in Surrey and Hants, but doubts are expressed as to its being 

 a native plant.] 



[C. LONG us, Linn. Sp. PI. 45 (1753), not of Herb. English Galingale. 



Syme, E. B. x. 41, t. 1578. Is recorded for Hants and South Wilts.] 



ELEOCHARIS, E. Br. Prod. Nov. Holl. 224 (i8io\ 

 Heliocharis, Lestib. Ess. Cyp. 41 (1819'. 

 H. acicularis, R. Br. 1. c. Slender Club Rush. 



Scirpus acicularis, Linn. Sp. PI. 48 (1753). 

 Top. Bot. 442. Syme, E. B. x. 50, t. 1585. Nyman, 767. Fl. Oxf. 321. 

 Native. Paludal. IMuddy bottoms or margins of ponds, canals, 

 streams, &c. Local, but where it occurs it is usually abundant. 

 P. July-Avigust. 

 First record. Scirpus acicularis, Mr. Kudge and Mr. Gotobed in Bot. 

 Guide, 1805. 



1. Isis. Near Eynsham Bridge, Silth. Canal near Shrivenham. 



Margins of the Thames between Eynsham and Godstow. 



2. Oek. Canal near Utfington, and between Wantage and Abingdon. 



Sparingly on Berkshire side of the Thames between Folly 

 Bridge and Iffley in a barren state. 



4. Kennet. Rather plentiful in the canal between Reading and 



Hungerford, especially about Padworth and Hampstead Marshall. 

 The muddy bottom is in places covered with it, in the form 

 submersa, Hj. Nilss. ; see Norman Fl. Arct. Norv. 43 (1893) : in 

 this condition it does not flower. Portions brought up by the 

 tow-rope of canal barges are easily recognized by the rhizome. 

 Careful search along the banks will usually be successful in 

 finding it in a fertile state. 



5. Loddon. Bulmarsh Heath, Paidge. Banks of the Thames rare, 



Gotobed, Bot. Guide, 1805. Virginia Water, rather plentiful in 

 places both in Surrey and Berks. In the lake near Sandhurst 

 it also occurs in both counties. 

 The Binsey Common locality cited in Mr. Britten's Contributions is in 

 Oxfordshire. 



When the mud from the canal is dredged and scattered along the 

 banks the previously submerged plant soon flowers and assumes the 

 ordinary condition. 



E. acicularis is recorded for all the bordering counties. 



H. palustris, R. Br. 1. c. Club Rush. 



Scirpus palustris, Linn. Sp. PL 47 (1753). 

 Top. Bot. 443. Syme, E. B. x. 51, t. 1586. Nyman, 767. Fl. Oxf. 320.
