ments of the lower leaves subspathulate and. more divergent than is 
usual in F. officinalis ; the spikes furnished with numerous flowers, some 
of them, when the plant is in seed, being fully two inches in length ; 
the petals much paler than in ordinary F. officinalis ; the sepals ovate- 
lanceolate, slightly toothed, narrower than the corolla, and an eighth 
of an iuch in length ; the fruit rugulose as in F. officinalis and similar 
in shape, that is, decidedly broader than long and depressed at the 
apex." Perhaps another year Mr. Webb may be able to procure fur- 
ther specimens of the plant and seeds for cultivation. The characters 
which separate it from F: officinalis seem to be of trifling value; and 
Miss Gifford sends from: Somersetshire a plant with equally diffuse 
habit of growth and divergent leaf-segments, but with flowers almost 
or quite as deep in colour as in the usual forms of this latter. 
Camelina sativa, Angl.—In the last edition of the ‘ Manual,’ Profes- 
sor Babington states that he has not met with C. sativa, Fries, in this 
country. l have gathered it in numerous stations in North Yorkshire, 
and have distributed, at different, times, well-developed specimens 
through the Club; whilst, on the contrary, I have never gathered or 
seen British examples of C. fetida. Under these circumstances, it 
may be worth while, though the plants are mere interlopers, for our 
members to examine their specimens with a view to ascertain which of 
the two their herbaria contain, and what has been their relative and 
absolute dispersion through Britain. . C. fwtida, Fries, has inflated 
obovate-subglobose silicles, truncate at the apex ; comparatively short 
styles; comparatively short and loose spikes of flowers, with the lower 
pedicels subpendulous in the mature plant; and entire, or dentate, or 
sinuate-pinnatifid leaves with acute auricles. I have it from Belgium 
aud Germany. | C: sativa, Fries Mant., has obovate, ventricose, but not _ 
inflated silieles, rounded towards the apex, and harder in texture than 
im C. fætida ; elongated and branched spikes of flowers, with compa- 
ratively short, patent or erecto-patent pedicels; and usually entire 
leaves with short auricles. C. dentata of Persoonis C.fetida ; . C. den- 
tata of Hornemann and the “Summa Vegetabilium ” of Fries is C. sa- 
tiva; C. sylvestris, Wallr., is a more slender plant than the other two, 
More rigid and more hairy, with a firm, often unbranched. stem ; firm, 
hard, pyriform  silicles, rounded towards the apex, and with a more 
conspicuous margin than the other two; styles about half as long as 
the silicles ; erecto-patent pedicels, and almost entire leaves. ‘L have
