14 mr. w. g. Clarke’s botanical notes from breckland. 
A grass found in St. Helen’s Well, Santon. was identified 
by Mr. F. Long and confirmed by Mr. A. Bennett, F.L.S., as 
Festuca ambigua, Le Gall. It was found in the same neigh- 
bourhood some years ago by Mr. Bennett. This is a decided 
sand-dune species in Kent and France. 
The best find, however, of Mr. Burrell and myself was one 
dwarfed plant of Phegopteris calcarea , F ee= Polypodium 
calcareum, Sw. = Polypodiitm Robertianum, Hoffm., a species 
which had not previously been recorded for East Anglia, 
nor from any county nearer than Northamptonshire. It 
was growing on the mortar between the bricks on the north 
side of a railway bridge, in the parish of Santon, Norfolk, with 
many specimens of Asplenium Adiantum-nigrum, L.. and 
Scolopendrium vulgare, Symons. This bridge is over a cut 
connecting the river Little Ouse with a huge chalkpit, and 
on many of the bricks there is a limestone incrustation. 
There are also limestone stalactites beneath the arch, probably 
(as Mr. Burrell suggests) due to calcareous water raised by 
capillary attraction. The single frond taken is just two inches 
long, the distance from the tip to the base of the lowest 
pinnae being in., while the breadth of these pinnae is 
ij inches, and of the next T ° F inch. With a good lens the 
glandular hairs on stalk and pinnae are very obvious. The 
plant was first identified by Air. W. H. Burrell, and con- 
firmed by Dr. L. Remington Pegler and Mr. Arthur Bennett, 
F.L.S. 
On August 23rd, Mr. A. Mayfield, M.C.S., and I visited the 
fens near the source of the Little Ouse at Hinderclay, 
Thelnetham, and Bio’ Norton, the last named in Norfolk. 
A considerable portion of the first named consists of light land, 
a few feet above the river, on which grows heather and furze, 
Solidago Virgaurea, L., Genista anglica, L., and other heath- 
land plants, while on the boggy portions grow Sagina nodosa, 
Fenzl., Poterium officinale, Hook., Epilobium hirsutum, L., 
E. montanum, L., E. palnstre, L., Parnassia palustris, L., 
Drosera rotundifolia, L., Anagallis tenella, L., Utricularia 
vulgaris, L., Menyantlies trifoliata, L., Pedicularis palustris, L., 
Alisma ranunculoides, L., Epipactis palustris, Crantz,
