l8o THE FAUNA AND FLORA OF FLORDON COMMON. 
the species found on the marsh are not numerous, for it 
offers little variation of habitat, the number of individual 
plants of certain species is amazing, especially of those 
mentioned as dominant. To these may be added the four 
Ranunculi, Lychnis Flos-cuculi, Hydrocotyle vulgaris, Galium 
palustre, G. uliginosum, Menyanthes trifoliata, Juncus inflexus, 
J . sylvaticus, Carex pulicaris, C. Goodenowii, C. flacca, C. flava, 
and C. hirta. 
Three bryophytes found on the marsh are specially note- 
worthy. Splachnum ampullaceum recorded from numerous 
localities in the older lists is now rare in the Eastern Counties ; 
this is the only recent record for Norfolk. A liver- 
wort belonging to the genus Morckia — probably Morckia 
Flotowiana — was detected in 1909. and has since been seen 
at Whitwell and Bio’ Norton. In Britain this species is 
almost confined to damp, sandy ground near the sea. As 
our marsh plant differs in habit from the tufted growth of 
the coastal sand dunes, it seems advisable to keep it under 
observation until mature spores are available. A liverwort 
belonging to the Mulleri group of the genus Lophozia was at 
first assumed to be Lophozia Mulleri; but doubt having 
arisen, it was sent to Professor Schiffner of Vienna, who 
detected the paroicous inflorescence and placed it under 
Lophozia Schultzii, as a new variety, for which he proposed 
the varietal name “ laxa.” The type occurs from Branden- 
burg — approximately in the same parallel of latitude as 
Norfolk— northwards to near the Arctic Circle in Lapland, 
Siberia, and Yukon ; it has been seen most frequently in 
Scandinavia, but has not been recorded for the British Isles. 
Although no attempt has been made to deal with the 
fungus flora of the common, a passing reference may be made 
to a species of Mycetozoa not previously recorded for Britain. 
It was identified by Miss Lister as Chondrioderma asteroides, 
first found in the South of France on fir-needles, &c., in 1902* 
and since recorded from Portugal, North Germany and 
Colorado on fir-needles, Eucalyptus, Alder twigs and wood.
