THE FAUNA AND FLORA OF FLORDON COMMON. 179 
Plants of the Marsh. 
The largest and most interesting part of Flordon Common 
is undoubtedly the marsh, in which we have included an 
area of rough pasturage at the north-eastern end, as 
well as that where Carex- J uncus is dominant. The 
latter includes a small triangle on the western common. In 
the winter this part is tawny of aspect, becoming green in 
the spring, brownish-purple at the end of May, brown at 
the end of June, and gradually changing to tawny. This 
colouring is mainly due to species of J uncus — J uncus 
subnodulosus appears to be the dominant plant — and Carex, 
with Schcenus nigricans also very abundant. Apart from 
these, during the spring and summer months, various flowering 
plantsappear successively to preponderate, Cardamine pratensis , 
being followed in succession by Valeriana dioica. Orchis 
latifolia, Eriophorum angustifolium, Pinguicula vulgaris, 
Helleborine longifolia, Drosera anglica, Pedicularis palustris, 
Parnassia palustris and Scabiosa Succisa, with Potentilla 
procumbens as perhaps the most widely distributed plant in 
flower throughout the summer months. Drosera anglica 
is the only sundew that occurs, rotundijolia appearing to need 
a peaty soil. The local name for the sundew at Flordon is 
the “ murder-plant,” and particularly in August we noted 
many moths and butterflies caught thereon, a green- veined 
white butterfly fluttering from one leaf to another until the 
sixth permanently imprisoned it by the tip of one wing. There 
appears to be practically no grass growing on the marsh, 
save a few small areas of Molinia ccerulea, the foundation of 
the marsh floor being moss, principally Hypnurn cuspidatum and 
Hypnum molluscum. There are also a number of small 
hillocks, a foot or two higher than the bulk of the marsh, and 
of course considerably drier. On some of these there are 
closely-cropped portions consisting chiefly of sedges, hirta 
and glauca, the few grasses present being Holcus lanatus, 
Briza media and Festuca ovina. To these hillocks 
Ophioglossum vulgatum is apparently confined, while they 
also abound in Polygala vulgaris and Plantago media. Though
