VIOLACE.E. 
That our knowledge of local violets has advanced so far 
during the last few years is mainly due to the initiative of 
Mrs. Gregory, who has very critically studied the plants of 
the neighbourhood of Weston-super-Mare. She was the first 
to recognize the odorata x hirta hybrids ( V. permixta Jord.) in 
the Worlebury Wood, and to point to the presence of V. cal- 
carea Bab. on the hmestone hills of N. Somerset. The latter 
fact is especially interesting because the plant can no longer 
be found at the original station near Cambridge. The char- 
acters of this variety are well marked and permanent in culti- 
vation, separating it distinctly from small states of V. hirta. 
Mrs. Gregory also detected the rosea form of this species, and 
the form villosa of V . Riviniana. The latter, however, is a 
very slight variation, and becomes glabrous in cultivation. 
A very beautiful violet is the form lactiflora of F. hirta, which 
grows in plenty on high ground between Brockley and Goblin 
Combes and on Cadbury Camp. Its flowers are large and 
almost pure white. The 2)ermixta hybrid first mentioned is 
well distributed in the districts on hmestone. In some of the 
plants the odorata element preponderates, while others are 
nearer hirta. 
CARYOPHYLLACE^. 
Dianthus Armeria occurs rarely and as a rule in very 
small quantity. A few plants have been found near Congres- 
bury, at Clevedon, Bourton and Brockley. Quite recently 
Mr. A. E. B. Gregory came upon a large colony of this pink 
at Cadbury Camp. D. prolifer grew sparingly at " Holly 
Gess," near Kingswood, 1883 to 1888, but then disappeared. 
D. deltoides was discovered (1886) by Mr. D. Fry, in a pasture 
between Keynsham and Brislington, whence no doubt the 
specimen in Herb. Jenyns (1867) was obtained, and probably
