180 ENGLISH BOTANY. 
scarcely in 2 rows, the narrowness of the pod bringing them into 
1 irregular row. Plant yellowish green, glabrous, or with a few 
hairs on the upper part of the stem. 
N. rivulare of Reichenbach, Tab. LIIT. Fig. 4365, and N. 
anceps (D. C. non Reich.), Billot’s exsice. No. 314, appear to me 
to be only states of the present plant, not even worthy of the 
name of varieties. I have seen the pods shorter than, equal to, 
and longer than the pedicels, all on the same plant.

No rootstock. Leaves deeply pinnatifid or sub-lyrate, with the 
segments irregularly toothed. Petals not longer than the sepals, 
yellow. Pods ovoid or oblong, about as long as the pedicels; 
valves without a dorsal nerve; style much shorter than the width 
of the pod. Seeds in 2 rows in each cell of the pod. 
In damp places, especially by the sides of ponds which partly 
dry up in summer. Not uncommon in England and the South of 
Scotland, where Aberdeenshire and Argyleshire appear to be its 
northern limit. 
England, Scotland, Ireland. Annual or Biennial. 
Summer, Autumn. 
Stem erect, 3 inches to 2 feet high, branched. Leaves deeply 
pinnatifid, sometimes almost pinnate, with the lateral segments 
oblong, and the terminal one usually ovate. Flowers about $ inch 
across, yellow, with a spreading calyx. Pedicels about + inch long, 
slightly deflexed. Pods + to $ inch long, much swollen, so that 
the length is not more than twice or thrice the breadth, the apex 
suddenly contracted into the extremely short style, which is usually 
little more than half the diameter of the pod. Seeds somewhat 
angular, roundish oblong, pale yellowish brown, finely punctured. 
Plant yellowish green, glabrous.
