Cross Church, Devon.” — T. 1C Archer Briggs. This is the first time 
that 1 have seeu British specimens of this sub-species of C. sativa. 
Sisymbrium pannonicum, Jacq. Railway banks, Crosby, Lancashire. 
“ This has become well established in the borders of fields, roadsides, 
waste places, etc., at Crosby, Lancashire. It was first observed (1858) 
here by Mr. II. S. Fisher, and is now almost the commonest Crucifer in 
the neighbourhood of Crosby Station. I do not think the plant has been 
introduced with ballast, or foreign hay, but am inclined to think it was 
sown, — this assumption, from seeing a specimen dated 1S16, in the herba- 
rium of the Liverpool Botanic Gardens, as having been grown in the garden ; 
and knowing that certain men in the botanic garden were good local 
botanists at about the year of the Sisymbrium being first found, they 
very likely sowed seeds which have now resulted in a common plant about 
Crosby.” — J. Harbord Lewis. 
Brassica Napus, L. and its allies. “ Very few examples of the Rape, the 
Swede, and the common Turnip, sent in order to show their dilferences 
when flowering in spring, or early summer, as the casual relicts from sown 
crops of the preceding year. These three plants appear to be sufficiently 
distinct species, although ill-distinguished and incorrectly described in 
books. Napus, or the Rape, is described as having all the leaves smooth ; 
but this is a mistake. The young leaves of the young plants are thinly 
covered with soft bristles, from petiole to marginal dentations. As the 
leaves expand, and also under pressure in the drying papers, many or 
most of these bristles fall off ; and all have disappeared, through the 
fading of the lower leaves, long before the plants come into flower. Once 
fairly known, however, there is no difficulty in distinguishing these three 
species, either as young plants the first season, or as flowering plants of 
the following year. The three gradations of size and the three varieties 
of tint in the flowers are perhaps the best practical distinctions in the 
living plants. The relative position of open flowers and unopened buds 
is somewhat uncertain ; and the forms of the stem leaves vary with the 
vigour of the plants.” — II. C. Watson. 
Polyyala oxyptera, Reich. Sandhills, Wallasey, Cheshire. “ In ‘ Eng- 
lish Botany,’ third edition, vol. ii., p. 36, this is said to grow at Sea- 
combe. As the Polygala is, with us, a sandhill plant, Wallasey must have 
been intended when Seacombe was quoted. On the Cheshire side the 
plant grows at Hoylake and Wallasey in great quantity. On the Lan- 
cashire side it grows at Waterloo and Formbv. If the sandhills round
