Juncus ranarius^ Nees. [Ref. No. 4919.] Teste Prof. Graebner. 

 See Report 1911, p. 35. Dr Graebner tells me that Buchenau became 

 convinced that it was a good species. In the sandy hollows on the 

 golf course, Pyrford, Surrey, July 1912. — Lady Davy and G. C. Druce. 

 " Opinions in this will differ; to me it is only a variety of hufoniusy — 

 A. Bennett. 



Luzula Forsteri, DC. Bank near Tidenham Railway Station, 

 v.-c. 34, May 6, 1911. — ^H. J. Riddelsdell. "Yes; but I call it 

 Juncoides." — G. C. Druce. 



Sjmr(/a7iium 7ieglectum, Beeby. [Ref. No 904.] Rescobie Loch, 

 v.-c. 90, N.C.R., Sept. 11, 1912.— R. and M. Corstorphine. "Yes; 

 Dr Ostenfeld and I gathered it in this locality on the Brit. Ass. 

 Excursion last September. It is a new county record." — G C. Druce. 

 " Only one specimen sent." — J. Cryer. 



Scheuchzeria palustris, li. On the Moor of Rannoch, associated 

 with Car ex limosa, Drosera anglica, etc. From Mr Scarth's locality, 

 where he discovered it in 1910. In some quantity over a limited area, 

 and fruiting freely. I collected this in somewhat trying climatic 

 conditions in August last, and with all care on account of its rarity ; 

 thus, with the exception of Sayina Boydii, I have gathered all the 

 Scottish plants.— G. C. Druce. "For the discovery of the plant in 

 Argyll, see Notes from the Royal Bot. Garden Edinh.^ p. 57, t. 60, 

 Jan. 1912." — A. Bennett. 



Fotamogeton nata7is, L., forma. [Ref. No. 3006.] Between the 

 Middle and Lower Lakes, Killarney, Aug. 1911. This plant, which 

 appears always to be barren, was considered by the foreign botanists 

 on the International Phytogeographical Excursion to be a form of the 

 above species. — G. C. Druce. " No form ! simply the plant coming 

 on to maturity, and of which Fryer possessed a remarkable series."— 

 A. Bennett. " Apparently a deep-water form, or state, of P. poly- 

 gonifolius.'' — E. S. Marshall. 



Potamogeton natans, J^., forma. [Ref. No. 4799.] Great Bedwyn, 

 Wilts. The bright reddish coloured young barren form sent me, in 

 May 1912, by C. P. Hurst ; comm. — G. C Druce. " Simply an early 

 state of the species in the form that Syme named P. j^olygonifolius, 

 var linearis, from the Killarney Lakes, etc." — A. Bennett. "Is not 

 this P. polygo7iifolius1 I cannot see the joint below the lamina, 

 characteristic of P. 7iatans.^' — E. S. Marshall. 



Potamogeto7i alpinus, Balb. Lunan Burn, near Loch Cluny, v.-c. 89, 

 Aug. 1911.— McT. CowAN, jun. — "Yes; an ordinary form of the 

 species." — A. Bennett.
