32 THE CRUCIFER FAMILY. [ Cardamine. — 
In moist meadows, and along brooks and streams, common throughout 
Europe, Russian Asia, and arctic America. Abundant in Britain. 7. 
spring and early summer. ['There are two remarkable varieties, C. dentata, 
Schult., a tall plant with fewer larger angled and toothed leaflets; and 
C. Hayneana, Welw., with the habits of CO. hirsuta, many small leaflets, 
and small white flowers, and narrow petals; found at Mortlake by the 
Thames. ] 
3. C. impatiens, Linn. (fig. 65). Narrow-leaved Bittercress.—An 
annual, with a stiff, erect, leafy stem, a foot and a half high, simple, or with 
a few erect branches. Leaves pinnate, with numerous lanceolote or almost 
ovate segments, + to 34 inch long, and often deeply toothed or cut; the 
common leafstalk has, on each side, at its base, a curved linear appendage ~ 
embracing the stem, and resembling a stipule. Petals very minute, 
and sometimes wanting. Pods numerous, about an inch long, the valves 
rolling back at maturity, with much elasticity. 
On moist rock, and in shady waste places, over a great part of Europe 
and Russian Asia. In Britain, scattered over central and northern Eng- 
land, very rare in Ireland. 7. summer. 
4, C. hirsuta, Linn, (fig. 66). Hairy Bittercress.—An annual, of a 
deep green colour, often much branched at the base, with ascending or 
erect stems, sometimes a foot high, but usually not half so much, with a 
few scattered hairs, which, however, are often very inconspicuous. Leaves 
pinnate, the segments small, those of the lower leaves ovate or rounded, 
and angularly toothed, the upper ones narrower and more entire. Flowers 
small and white, the petals seldom twice the length of the very small sepals. 
Pods in a rather loose raceme, about 6 lines to 1 inch long. 
On moist or shady banks, waste and cultivated places, throughout the 
temperate regions of the globe. Abundant in Britain. FV. spring and all 
summer. It varies much, like other Cardamines, in the length and thick- 
ness of the style ; and in the common small form the stamens are usually 
reduced to 4. A large luxuriant variety, with 6 stamens and slender style, 
is sometimes distinguished as a species, under the name of C. flexuosa, 
or sylvatica, Link. 
5. C. bulbifera, Syme (fig. 67). Bulbiferous Bittercress, Coralroot.— 
Stem weak, 1 to 13 feet high, bearing several leaves, often with a small 
ovoid bulb in their axils, the lower ones pinnate, with 5 or 7 segmenis, the 
upper ones with fewer segments, or quite undivided; all the segments lan- 
ceolate, entire or toothed, tapering at the base, mostly 13 to 2 inches long. 
Flowers few, rather large. The pod is seldom formed, as the plant usually 
propagates by the axillary bulbs falling to the ground, and there growing. 
In damp woods, and shady places, chiefly in mountain districts, spread 
over Continental Europe from Scandinavia and Central France to the 
Caucasus. In Britain occurring from Stafford southwards to Kent and 
Sussex. Fl. spring. Dentaria bulbifera, Linn. 
This species, with a few exotic ones from the northern hemisphere formed 
the Linnean genus Dentaria, kept up in the first edition of this work 
under the name of Toothcress, but the supposed characters are so slight, 
resting on the rather broader pod, and the little seedstalks being usually, 
but not always, flat and broad.
