BRISTOL FIELD-BOTANY IN 1901. 
also Dr. Thwaites' record for N. Somerset in Topographical 
Botany. D.ccesius is not quite confined to Cheddar Cliffs. 
I have seen it on rocks two miles from the Gorge, and Mr. 
Read tells me that a small patch exists in Brockley Combe, 
where I hardly think it can be native. 
Sagina ciliata proves to be well distributed. I have seen 
it on the Downs between Pembroke Road and Sea Walls, on 
Brandon Hill, Rodway Hill, Siston Common, near Keynsham, 
on Mendip above Ebbor, and on Brean Down in plenty. S. 
maritima was abundant by the Avon at Lamphghters in 1894 
and subsequently. 
Arenaria tenuifolia is undoubtedly a Bristol plant. Besides 
Penpole Point, where it grows in quantity, this plant has 
several locahties on and about the local railways for which 
it shows a peculiar liking. A. leftocladus Guss. may not be 
a distinct species as is sometimes contended, but its slender 
habit and flexible capsules enable one to easily separate it 
from A. sphwrocarpa, than which it is often more abundant. 
Gerastium arvense. New to the district. Discovered in 
1894 by Mrs. Gregory on a hillside above Loxton, and near 
Portbury in 1900, by Miss Ida Roper. G. fwnilum is now 
known to be frequent on hmestone hills at Clevedon, Worle, 
Cheddar and elsewhere. G. quaternellum {Moenchia) has 
been found abundantly in Dr. Stephen's old locality near 
Keynsham, but cannot be rediscovered at Brandon Hill. 
Lepigonum ruhrum exists on Brandon Hill, Troopers' Hill, 
and by the side of the high road at Bitton. Plants answering 
to L. salinum Fries, and to L. neglectum Kindb. have been 
gathered on the sea-banks and shore of the Channel at Avon- 
mouth, Clevedon and Burnham. 
Scleranthus annuus. Plentiful in a rough pasture on pen- 
nant, N.W. of Keynsham. In the Bristol district this is one 
of the rarest of the Caryophyllaceae. Ahen plants of this order 
that occur in the district are Saponaria Vaccaria L., Silene 
noctiflora L., and S. dichotoma Ehrh.
