MR. W. A. NICHOLSON ON BOTANY OF SUTTON. 
-75 
says, “ A very remarkable group of plants, growing on 
stones, etc., in swiftly flowing streams and rivers of the tropics.” 
It is obvious, the conditions required by this type, do not 
occur at Sutton. 
Some notes made in July, 1905, on Plant-associations 
amongst the aquatics may be of interest in helping to form 
a general idea of the aspect of the vegetation. The plants 
are arranged roughly, in comparative order of abundance. 
Sutton Broad, Stalham side. 
♦SciRPUS LACUSTRIS, L. 
Phragmites communis, Trin. 
♦Ranunculus Lingua, L. 
♦Castalia speciosa, Salisb. 
♦Nymphea lute a, L. 
♦Utricularia vulgaris, L. 
Menyanthes trifoliata, L. Thick under-growth of 
leaves, flowering being over. 
The surface of a dyke at Fenside, Catfield, was almost 
■entirely covered with Scirpus fluitans, L. This dyke formed 
a very interesting sight, as the following plants had grown 
through the thick mass of Scirpus and were flourishing. 
Nasturtium officinale, R. Br. 
POTENTII.LA PALUSTRIS, Scop. 
J UNCUS LAMPROCARPUS, Ehrh. 
A dyke (Border Dyke) at Sutton was also full of Scirpus 
fluitans, L., in this case associated with 
Stratiotes aloides, L. 
Sagittaria sagittifolia, L. 
POTAMOGETON NATANS, L. 
Osborne’s Dyke along the road-way leading to the 
Laboratory contained a luxuriant growth of 
Alisma Plantago-aquatica, L.. with 
Glyceria fluitans, R. Br., and 
Nasturtium officinale. R. Br. 
A dyke on the eastern boundary of Hand Marsh, Sutton, 
apparently very full of Elodea Canadensis, Michx, contained 
also Stratiotes, Hydrocharis, Nymphea lute a. 
* Those marked with an * were in flower.
