plant has intermediate characters between two species, it need not 
necessarily be a hybrid. 
2893. Polystichum acnleatmu Roth. var. lonchitioides Deakin. 
Christensen puts this as P. lobntum var. Plukenetii (Lois) l.c. 127, 
but I am not certain which name has priority: they are, I take it, 
synonymous. 
2923 (2). Azolla filiculoides Lam. We are indebted to Dr. 
Ostenfeld for determining the Azolla from Norfolk as this species, 
as I collected no specimens. This year, however, through the 
kindness of Mr. J. Cator, M.P., I have had specimens from Wood- 
bastwick, which prove the accuracy of Dr. Ostenfeld’s determi¬ 
nation. Our generous host, Mr. Beamish, also sent me specimens 
from the brackish waters near Queenstown Junction, which prove 
to be the same species (teste N. E. Brown) and additional to the 
Irish list. A. cavoliniana Willd., however, occurs in the Cherwell, 
near Oxford and in the Thames near Sonning and Henley, as well 
as in the Pang, near Suleham, Berks. 
As one practical outcome of the Excursion may be mentioned the 
acquisition of Blakeney Point with its interesting accumulation of 
shingle, which Professor Oliver has made the scene of his own patient 
and minute investigations, and which proved to our visitors an ex¬ 
tremely fascinating area both for its ecological and floristic value. It 
therefore appeared to be most desirable that it should be preserved 
for all time as a nature-reserve, since besides the points of 
interests alluded to it, has a rich bird fauna and many interests 
for the entomologist, as well as much scenic charm. Fortunately, 
through the generosity of the Fishmongers’ Company and some 
others interested in the matter, a sufficient sum of money was 
placed in my hands, and through the kind help of Professor Oliver 
and other persons the troublesome and lengthy negotiations for 
purchase were eventually successful. To the shingle bank has 
been added an additional area of “ saltings.” This makes the 
reserve more homogeneous, and brings the total area acquired to 
more than 1,000 acres. Under certain conditions, and with the 
appointment of special trustees, the property has now been handed 
over to the National Trust; an object lesson, which it is hoped will 
have its effect in securing many other spots of interest to the 
naturalist and preserving them, as far as possible, in their pristine 
condition for all time.
