44 THE CRUCIFER FAMILY. [ Thlaspt. 
biennial or perennial, forming a shortly-branched or tufted stock, with 
obovate oval or oblong, stalked, radical leaves. Stems simple, erect or 
ascending, about 6 inches high; the leaves narrow, clasping the stem with 
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 between 
them. Style prominent. Seeds 6 or 8 in each cell. 
In mountain pastures, in limestone districts, in central and southern 
Europe, extending northward to southern Sweden, and eastward to the 
Russian frontier. In Britain, chiefly in the north of England, but found 
also in some other parts, as well as in Wales and Scotland. Fl. summer. 
[Slight varieties, depending on the depth of the noteh 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 Léeris; but the longer filaments have a scale-like appendage 
near their base, and the pod has 2 seeds in each cell, 
A genus confined to two European species. 
1, T.nudicaulis, Br, (Fig. 98). Common Teesdalia.—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 one or two small entire or pinnate leaves. 
Flowers very small. Pods in short racemes, nearly orbicular, about 13 
lines in diameter, flat, with a narrow wing round the edge, and a small 
noteh 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. 
Fl. 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. One seed only in each cell, the radicle accumbent 
on the edge of the cotyledons. 
A genus of several south European and western Asiatic species, some of 
which are cultivated in our flower-gardens under the name of Candytufts 
and all readily known by the unequal petals. 
1, Z.amara, Linn. (fig. 99), Bitter Candytuft.—An _ erect, rather 
stiff, very bitter annual, 6 inches to near a foot 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.
