168 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 



Eleocharis uniglumis Schultes. Slacks in dunes, Freshfield, S. 

 Lanes, v.-e. 59, July 19, 1914.— W. G. Travis. 



Eleocharis multicaulis Sm. Name confirmed by Arthur Bennett. 

 [Ref. No. 227.] Marsh 30 feet above sea level, Valley Burn, 

 Rackwick, Hoy, Orkney, June 23 and September 9, 1914. Native. 

 Common in several small marshes. — H. H. Johnston. 



Scirpis filiformis Savi, var. monostachys Hook. Freshfield, S. 

 Lanes, v.-c. 59, July 17, 1914. — VV. G. Travis. Also sent from damp 

 ground, sea cliffs, Milford-on-Sea, S. Hants, v.-c. 11, August 1914. — 

 J. Comber. " Yes." — E. S. Marshall. 



Scirpus fluitans L. Near Yarn ton, Oxon, June 1914. Sent in 

 order to put on record a curious instance of plant occurrence. 

 aS*. fluitans is one of our rarest species, being only known from two 

 localities, neither of which has recently yielded it. The place where 

 I found it last year was well known to me in the eighties, as it was 

 then a shallow piece of water, rich in Charas. Since 1 900 the water 

 level of one area has sunk, and vegetation — Carex, Sparganitmi, Iris, 

 ikc, have asserted themselves. In the dry period when I visited it 

 there was but little water, but the surface of the wet ground was 

 covered with masses of this Scirpus, which must have been brought, 

 probably by aquatic birds, and finding a congenial home, with little 

 competition, was thus enabled to make in a few years this remarkable 

 increase. — G. C. Druce. 



Eriophorum angustifolium Roth, var. alpinum Gaudin =var. 

 minus Koch = E. gracile Smith, non Roth. [Ref. No. 3943]. 

 Plentiful in bogs, north-east corrie of Ben Chaluim, Mid Perth, v.-c. 

 88, from 2300 to 2500 feet, July 20, 1914.— E S. Marshall. " Yes, 

 and as usual with Mr Marshall's gatherings beautifully preserved ; 

 strictly speaking I suppose the spikes should be pedunculate." -G. C. 

 Druce. 



♦ 



Carex vesicaria L. Marshy places, Naseby reservoir, Northants, 

 v.-c. 32, June 20, 1914. Spikelets appear to be much more cl(>sely 

 sessile than usual. — G. Chester. "Spikelets appear more closely 

 sessile than usual. Yes, this is so, but it varies greatly in this, the 

 other extreme (f . pendulina) has the lowest spikes drooping with stalks 

 three inches long." — A. Bennett. "Very fine. In Scotland and 

 Ireland it usually has similar short, stout, sub-sessile female spikelets." 

 — E. S. Marshall. 



X Carex csomadensis Simonkai in Enum. PL Transs. 556, 1887, 

 = C. riparia x vesicaria. [Ref. No. 4919]. Marshy meadow, Gren- 

 don Underwood, Bucks, July 1911. In considerable abundance.
