vi. chucifekyE : lepibineyE. [ Senebiera , 
typical form of the plant, with petals and six stamens, is as yet un- 
known, unless described as a distinct species. Stem sometimes a foot 
high, much branched. Seed-vessels numerous. Cotyledons incum- 
bent, as in most of this genus ; whereas those of its very near affinity, 
L. Virginicum, are accumbent. 
** Style as long as the pouch. 
3. L. * Drdba L. ( Whitlow P .) ; leaves amplexicaul broadly 
oblong or lanceolate entire or toothed, pouch cordate entire at 
the apex crowned with a style about its own length, valves 
turgid. E. B. S. t. 2683. 
Fields and hedges, rare. Swansea ; at St. Peter’s and Ramsgate, 
Isle of Thanet ; banks of the railway at Forest-hill, Surrey ; left 
bank of the Dee below Chester. Tf.. 5. 6. — Stem 8 — 10 inches to 
a foot high, branched, with large distant leaves and almost umbellate 
corymbs of numerous small flowers. Pedicels very long. 
*** Style filiform, much shorter than the pouch. 
4. L. campeslre Br. ( common Mithridate P .) ; pouch ovate 
emarginate winged rough with minute scales, style scarcely 
longer than the notch, cauline leaves sagittate toothed. Thlaspi 
L . : E. B.t. 1385. 
Corn-fields and dry gravelly soil ; not uncommon in England and 
Scotland. © or $ . 5 — 8. — Stems solitary, erect, 10 — 12 inches high, 
corymbosely branched above. Lower leaves almost spathulate, all 
slightly pubescent, as well as the racemes and pedicels. Pouch cu- 
riously scaly. 
5. L. Smithii Hook, (smooth Field P.) ; pouch ovate emar- 
ginate winged glabrous occasionally with a few minute scales 
on the back, style twice as long as the notch, cauline leaves 
sagittate toothed — Lepidium hirtum Sm. (partly). Thlaspi 
hirtum Sm. (not L.) : E. B. t. 1803. 
Borders of fields and hedges in Norfolk and Suffolk. Caernarvon- 
shire and Anglesea. Frequent, particularly in the west of Scotland. 
Belfast and Dublin, plentiful. It. 4 — 8. — Stems many from the 
same root, 6 inches to more than a foot high, diffuse, irregularly 
branched. Much resembling the last, but truly distinct. Pouch 
with a much longer style, quite glabrous, and smooth or even ; except 
that sometimes on the middle of the back there are a few minute 
scales. When glabrous it is the L. heterophyllum of Bentham, from 
the Pyrenees ; our common form is found, however, in the north- 
west of France. 
26. Senebiera Be Cand. Wart-Cress. 
Fruit broader than long, 2-celled, without valves or wings ; 
cells 1 -seeded. Cotyledons long, linear, curved. — Named in 
honour of M. Senebier , an eminent Genevese physiologist.
