England, but found also in some other parts, as well as in Wales and 

 Scotland. Fl. summer. A slight variety, with rather larger flowers, 

 has been distinguished as a species, under the name of T. virens. 



XIX. TEESDALIA. TEESDALIA. 



Dwarf annuals, with white flowers, two petals larger than the two 

 others, as in Candytuft; but the longer filaments have a scale-like ap- 

 pendage near their base, and the pod has 2 seeds in each cell. 



A genus confined to two European species. 



1. Common Teesdalia. Teesdalia nudicaulis, Br. (Fig. 97.) 

 (Iberis, Eng. Bot. t. 327.) 



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 

 \\ line in diameter, flat, with a narrow 

 wing round the edge, and a small notch at the top. 



On sandy and gravelly banks and waste places, in central and southern 

 Europe and western Asia. Bather 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.

XX. CANDYTUPT. IBEEIS. 



Glabrous or minutely downy annuals or branching perennials, with 

 narrow or pinnatifid leaves, and white or pink flowers ; two adjoining 

 exterior petals larger than the two others. Filaments without appen- 

 dages. 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.
