cultivated in our gardens ; among them the most common are the Honesty 
(Lunaria) and an Eastern species of Aubrietia, both belonging to the 
Alyssinee. 
I. MATTHIOLA. STOCK. 
Annuals or perennials, more or less hoary with stellate hairs, 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 surrounded 
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 Cheiranthus, from 
which they are chiefly cue Een by the erect stigmas, and the colour of 
the flowers.
