2. Sea Stock. Matthiola sinuata, Br. (Fig. 48.) 

 {Cheiranthus, Eng. Bot. t. 462.) 



Like the last, a perennial of short du- 

 ration, and covered all over with a 

 short hoary down, which is however 

 much softer and more dense. Branches 

 very spreading. Lower leaves deeply 

 sinuate. Mowers nearly as in the com- 

 mon 8., but the pods more compressed, 

 usually more or less covered with glan- 

 dular protuberances, and the stigmas 

 very short, scarcely thickened at the 

 base. 



On sandy seashores, common all 

 round the Mediterranean, and up the 

 west coast of Europe to Ireland, and 

 many points of the south and west coasts 

 of England and Wales. Fl. summer.

II. WALLFLOWER. CHEIRANTHUS. 



Habit and character of the Stoch, except that the flowers are orange 

 or yellow, the pod more distinctly flattened, the very short stigmas 

 spreading horizontally, not erect, and usually borne on a distinct style, 

 and the seeds not winged. 



The genus is reduced by some to a single species, by others made to 

 include also a very few species from southern Europe and the Canary 

 Islands. 



1. Common "WaUflower. Cheiranthus Cheiri, Linn. (Eig. 49.) 



(C.fruticulosus, Eng. Bot. t. 1934. Wallflower. Gilliflower.) 



A perennial of longer duration and more woody than the common 

 Stock, more branched and less hoary, the hairs forked at the base, and 

 closely pressed on the surface, or often quite green and nearly glabrous. 

 Leaves narrow, pointed, quite entire. Elowers rather large, generally 

 of a rich orange yellow, and sweet-scented, but varying from pale yel- 

 low to a deep red. Pods 2 to 3 inches long, the valves marked by a 

 slightly prominent midrib.
