THE CRUCIFER FAMILY. 



8. Lomentos^:. Pod lomentose. Genera : — 25. Woad ; 2G. Cakile ; 27. 

 Crambe ; 28. Radish. 



Several European and Asiatic Crucifers belonging to otlier genera 

 are cultivated in our gardens ; among them the most common are the 

 Honesty (Lunaria) and an Eastern species of Aubrietia, both belonging 

 to the Alyssinece. 



I. STOCK. MATTHIOLA. 



Annuals or perennials, more or less hoary, the leaves entire or sinuate, 

 the flowers rather large, usually purple, never yellow. Calyx erect, 

 distinctly bisaccate. Petals spreading, on long erect claws. Pod long 

 and narrow, compressed or nearly cylindrical. Stigmas sessile, short, 

 but erect, and parallel to each other, having sometimes a horizontal 

 horn at the base of each. Seeds more or less flattened, usually sur- 

 rounded by a narrow wing, forming one row. Radicle accumbent. 



Mostly seacoast plants from the shores of western Europe and the 

 Mediterranean. They formerly formed one genus with the Wall- 

 flowers, from which they are chiefly distinguished by the erect stigmas, 

 and the colour of the flowers. 



Stem erect, much branched. Leaves entire 1. Common S. 



Stem spreading. Lower leaves sinuate, or coarsely toothed . 2. Sea S. 



1. Common Stock. Matthiola incana, Br. (Fig. 47.) 



{Cheiranthus, Eng. Bot. t. 1935. Stock. Gilliflower.) 



An erect herb, usually perennial, and 

 almost woody at the base, but not of 

 long duration, 1 to 2 feet high, with hard, 

 slightly spreading branches. Leaves 

 oblong-linear, obtuse, quite entire, soft 

 and hoary on both sides with short 

 crisped hairs. Elowers purple or reddish, 

 rather large, the petals obovate. Pod 4 

 or 5 inches long, crowned by short 

 stigmas, which are rather thickened at 

 the base. 



On cliffs and stony places on the sea- 

 coast, round the Mediterranean, and up 

 western Europe, at least to Bayonne. 

 In Britain fully established as a wild 

 plant on cliffs in the Isle of Wight, and perhaps some other parts of 

 the south coast, although probably originally escaped from cultivation. 

 Fl. summer.
