1. Common Teesdalia. Teesdalia nudicaulis, Br. 



(Iberis, Eiig. 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 or- 

 bicixlar, about 1^ lines 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. Kather 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. CANDYTUFT. IBEEIS. 



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 ex- 

 panded 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. Bitter Candytuft. Iberis amara, Linn. 

 (Eng. Bot. t. 52, the injloreseeiice too much elongated^ 



An erect, rather stiff annual, 6 inches to near a foot high, with a few 

 erect branches forming a terminal flat corymb. Leaves oblong-lanceolate 

 or broadly Unear, with a few coarse teeth, or slightly pinnatifid, seldom 

 quite entire. Flowers white. Pod nearly orbicular, the long style pro- 

 jecting from the notch at the top. 



Common as a weed of cultivation in western, central, and southern 

 Europe. Appears occasionally in cornfields in England, especially in lime- 

 stone districts. Fl. with the corn. 



XXI. HX7TCHINSIA. HUTCHINSIA. 



Dwarf annuals or perennials, with pinnate leaves and white flowers, 

 separated from Cress as having two seeds in each cell of the pod instead 

 of one. 



A genus limited by some to one species, by others extended to a few 

 alhed ones from southern Europe and Russian Asia, or also to two or three 

 perennials from the high mountain-ranges of central and southern Europe. 



1. Rock Hutcbinsia. Hutchinsia petrsea, Br. 



{Le2nditim, Eng. Bot. t. 111.)
