fine seasons — also leads me to think that Semidecandrum is the 
correct name. 
We now come to Oxalis acetosella, another woodland plant of 
the same habit as Anemone nemorosa. Paget particularises it as 
now lost, having at one time been found in a small wood at Lound. 
I still find it growing in abundance also in a small wood, and also 
in Lound. 
The Portulacaceas is a natural order to which another species 
must be added. Claytonia perfoliata is now, I believe, accepted as 
a well naturalised plant. It was introduced into this country 
about 1825, by a botanist named Clayton, who brought it from 
Virginia. Since that time it has slowly spread and seems to have 
reached Gorleston, where it now grows, about 1860. If the species 
can boast a Cecil Rhodes amongst its numbers, it has not brought 
him to Gorleston, for it seems to find colonising a difficult matter. 
At present I have only found this Virginian exile in a hedge-bank 
opposite Gorleston cemetery, with scattered individuals for a length 
of about | mile along the road. It then turns down a lane, 
where it grows fairly abundantly. The lane opens out on the 
Beccles Road, and on this road it has its only other locality, at the 
cross road leading to Belton. Manila fontana, characterised by 
Paget as rather rare, is plentiful enough about the damp places on 
the North Denes. 
Of the Crassulaceae, Sedum anr/licum, which grows fairly abund- 
antly on the North Denes, has gradually disappeared from the 
South Denes. This will be found to be not the only example of a 
flower apparently unable to exist in the isolation of the South Denes. 
Of the Saxifragaceie, Paget reports that Parnaasia palustris is 
common at Gorleston. I have not yet had the pleasure of recog- 
nising this elegant flower amongst our nearer neighbours. It grows 
quite plentifully around Barton Broad, but I know of it nowhere 
else. It is probable that draining operations have driven it from 
Gorleston. Gorleston Common in particular, seems in days gone 
by to have been quite a happy hunting-ground ; but since then the 
sanitary officer has arisen, by whom no flower is allowed to blush 
unseen unless it can give a satisfactory account of its why and 
wherefore. Tempora mutantur et flares midantur cum Hits. 
Saxifracja rjranulata is plentiful at Cromer, but is rare enough in 
my neighbourhood to have escaped me at present. Sax if rap a
