500 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 



Mr Pearsall's specimens are substerile, but it evidently is a shy fruiter, 

 and my specimens of the var. confertus Doell, from Jersey are also in 

 good fruit." — A. Bennett. 



Juncus bulbosus L., var. fluitans (Lam.). Errisbeg, near Round- 

 stone, Galway W., Aug. 13, 1913, alt. 600 ft.— W. C. Barton. " J: 

 bulbosus f. uliginosus.^' — R. S. Adamson. "No, this is the var. 

 uliginosus (Fries) Druce." — G. C. Druce. " A viviparous state not a 

 true variety." — E. S. Marshall. 



Juncus bulbosus L., var. fluitans Lam. [Ref. No. 382.] Tarn 

 Hows, Coniston, v.-c. 69 b., Aug. 6, 1913. This dominates the 

 muddy margins of many mountain tarns in N. Lanes, but has not 

 been previously recorded. It is abundant in Tarn Hows, Coniston ; 

 in Low Water (1786 ft.) on the side of Coniston Old Man; and in 

 High Dam and Bortree Tarn (600 ft.) to the S.-W. of Lake Winder- 

 mere. In many seasons it does not flower, through the water not 

 falling sufiiciently. — W. H. Pearsall. "J. bulbosus f. confervaceus 

 Buchenau. I consider these so-called varieties of J. bulbosus to be 

 merely states due to the habitat conditions, and scarcely worthy of 

 varietal names." — R. S. Adamson. " A submerged state, not a true 

 variety." — E. S. Marshall. " Yes, the var. c. of my List, but 

 comparative culture is needed to define the true status." — G. C. Druce. 



Juncus tenuis Willd. On waste ground by the side of the Bridge- 

 water Canal, Sale, near Manchester, v.-c. 58, Aug. 1913. G. A. 

 Holt. See Report 1912, p. 289. A supply from a station ten miles 

 further west on the same canal is also sent by the same collector, 

 growing between and upon the blocks of sandstone lining the canal at 

 Lymm, Cheshire. — C. Bailey. " An addition to the county, I 

 believe." — C. E. Salmon. "(1) Are typical specimens. (2) Is a 

 peculiar form, but hardly a variety ; it only differs in the crowding of 

 the flowers. According to Rouy Fl. Ft. xiii., 247 (1912), both would 

 come under var. a. secundus Engelm., but this is certainly not the 

 J. secundus Beauv. = J. tenuis v. secundus Engelm. of Buchenau 

 Pflanzenr. iv., 36, 1906, 120."— R. S. Adamson. 



Luzula multiflora DC, var. congesta (Lej.). Hinderclay Wood, 

 W. Sufl'olk, v.-c. 26, June 6, 1913. -W. C. Barton. " Yes."— G. C. 

 Druce. 



Sparganiiim ramosum Huds. A deep-water form. In the Glou- 

 cester and Berkeley Canal where crossed by the branch of the Mid- 

 land Railway Co., Gloucester, v.-c. 33, July 7, 1913. Collected in 

 company with the Rev. Walter Butt. The ordinary erect form of the 

 plant grows on the margins of the canal ; but a deep-water form, 

 wholly submersed, with branches 4 to 6 feet or more in length, grows
