Potamogeton marinus, L. Rescobie Loch, Forfar, v.-c. 89, Aug. 



1911. — McT. Cowan, jun. "Mr McTaggart Cowan here uses the 

 name marhius, L. There is no specimen of marinus (i.e. fill for mis, 

 Nolte) in the Linnean Herbarium, the one so named being a 

 pectinatus, L., form. In another place I hope to show why we must 

 now use Linnaeus' name, notwithstanding there being no specimen in 

 his herbarium." — A. Bennett. " P. filiformis ; which Mr Druce, like 

 Nyman, identifies with P. marinus, L." — E. S. Marshall. 



Potamogeton densus, L. Croxton-Keyrial, Leics., v.-c. 55, Aug. 22, 



1912. — A. R. HoRWOOD. "Such specimens are not worth drying 

 unless as a new record to a county. It is one of the easiest to preserve 

 in the genus." — A. Bennett. 



Zostera marina, L. Sea sands at low tide near the Princess Pier, 

 Torquay, S. Devon, April 11 and 16, 1912. — C. Waterfall. "As far 

 as leaf material goes, this appears to be var. stenophylla, Aschers. and 

 Graebn."— -E. S. Marshall. 



Scirpus caespitosus, L., var. [Ref. No. 4779.] Rannoch Moor, 

 Perth, Aug. 1912. — G. C. Druce. "A form with the slenderness of 

 var. nemorosus, Roth, but not that." — A. Bennett. " Is the var. 

 germanicus (Palla) Aschers. and Graebn. See Report 1912, p. 180."

 formis was found while searching for the rare S. nanus in its ' locus 

 classicus.' " — A. B. Jackson.

 1910. — L. Gumming. "Recorded by the Rev. A. Ley in 1886 from 

 the Dyfi-Estuary marshes (Record Club Report 1887, 148.). The

 Salop, v.-c. 40, July 3 ; edge of Llyn Helig, Flint, v.-c. 51, July 13,
