44 THE CRUCIFER FAMILY. 
small auricles. Flowers usually larger than in the last two. Pod about 
3 lines long, but not so broad as in 7. perfoliatum, especially at the base, 
the wings rounded at the top, leaving a broad but not a deep notch be- 
tween them. Style prominent. Seeds 6 or 8 in each cell. 
In mountain pastures, in limestone districts, in Europe, extending 
northward to southern Sweden, and eastward to the Himalaya. In 
Britain chiefly on the hilly mountains of England, in Wales and Scot- 
land. Fl. summer. [Slight varieties, depending on the depth of the 
notch of the pod and length of the style, have been regarded as species 
by some authors. |

XVIII. TEESDALIA. TEESDALIA. 
Dwarf annuals, with white flowers, two petals larger than the two 
others, as in Jberis; but the longer filaments have a scale-like appen- 
dage near their base, and the pod has 2 seeds in each cell. 
A genus confined to two European species. 7 
1. T. nudicaulis, Br. (fig. 99). Common T'.—Leaves radical and 
spreading, about half an inch long or but little more, usually pinnate, 
the terminal lobe larger, obovate or orbicular, glabrous or with a few 
stiff hairs. Flower-stems 2 or 3 inches high, erect and leafless, or the 
lateral ones rather longer, ascending, with 1 or 2 small entire or 
pinnate leaves. Flowers very small. Pods in short racemes, nearly 
orbicular, about 14 lines in diameter, flat, narrowly winged round the 
edge, and notched at the top. 
On sandy and gravelly banks and waste places, in central and southern 
Europe and western Asia. Rather generally distributed over England 
and southern Scotland, though not a very common plant, and not in 
Ireland. FV. at any time from spring to autumn. 
XIX. IBERIS. CANDYTUFT. 
Glabrous or minutely downy annuals or branching perennials, with 
narrow or pinnatifid leaves, and white or pink flowers ; two adjoining ex- 
terior petals larger than the two others. Filaments without appendages. 
Pod orbicular or oval, laterally flattened (at right angles to the narrow 
partition), notched at the top, the valves boat-shaped, the keel or midrib 
expanded into a wing; the cells 1-seeded, the radicle accumbent. 
A genus of several south European and western Asiatic species, some 
of which are cultivated in our flower-gardens under the name of Candy- 
tufts, and all readily known by the unequal petals. 
1. I. amara, Linn. (fig. 100). Bitter C_—An erect, rather stiff, very 
bitter annual, 6 to 12 inches high, with a few erect branches forming a 
terminal flat corymb. Leaves oblong-lanceolate or broadly linear, with 
a few coarse teeth, or slightly pinnatifid, seldom quite entire. Flowers 
white. Pod nearly orbicular, the long style projecting from the notch 
at the top. 
Common as a weed of cultivation in western, central, and southern 
Europe. Appears occasionally in cornfields in England and Scotland, 
especially in limestone districts. Fl. with the corn.
