TETRADYNAMIA. SILIQUOSA. 
THALAMIFLOR#. CRUCIFERZ. 
MATTHIOLA. (Srock.) 
Generic Character. Pod rounded, or flattened at the sides. 
Stigma of two erect lobes, convex or horned at the back. Calyx 
erect. 
Marrutiota iIncaNA. Stock. This well-known garden 
plant is found growing near the sea, but even then supposed 
not to be truly wild. It is seen on cliffs eastward of 
Hastings. I have little doubt that I saw it growing on the 
sea cliffs near Ventnor, in the Isle of Wight, but too high 
for examination. Stem shrubby, upright and branched ; 
leaves lanceolate, horny, entire; pods cylindrical. Another 
species, Matthiola sinuata, is found on the sandy shores of 
Cornwall and Wales. It has large purple flowers, which are 
fragrant at night. Stem herbaceous, spreading; leaves 
oblong, downy ; pods compressed.
