502 JUNCACEAE 



may be included under this name have been noticed at Sandhurst, 

 Finchampstead, &c. 



Var. KocHii (F. W. Scliultz, in Pollichia, 13 (1855) 32), which has 

 six stamens, and is the only variety of J. buWosus admitted by Buchenau, 

 I have only seen near Sandhurst. 



The distribution of J. hulhosus is exactly the reverse of J. glancus, as 

 it is almost absent from the Isis, and rare in the Ock district. 



J. bulbosus occurs in all the bordering counties. 



J. articulatiis, Linn. Sp. PI. 327 (1753) teste Beck, Fl. Nied.-Oesterr. 

 and Richter, PI. Europeae.

 Native. Uliginal. "Wet meadows, pond-sides, ditches, wet heaths, 



&c. Common in all the districts. P. June-September. 

 First record. J. ariicidatus, Dr. Noehden, Mavor's Agr. Berks, 1809. 

 (In an aggregate sense.) See also Mr. Baxter s MSS. 1823. Pub- 

 lished as J. lamprocarpus in Russell's Cat. 1839. 



It is common in all the districts and is occasionally viviparous, as 

 by the side of Virginia Water, at Sandhurst, Snelsmore, Wytham, 

 Burghfield Common, &c. 



Sometimes a floating state is found along the margins of ponds 

 which appears to be the var. fluitans (Koch, Syn. Fl. Germ, 730 (1837 . 

 as a var. of J. lamprocarpus) . 



On the gravelly soil at Theale near the railway it occurred in a more 

 erect form with darker and more prominent fruit, and approaches th«^ 

 var. nigritellus. 



J. articulatus is found in all the bordering counties.
