M. sinuata, var. oyensis, Rouy et Foucaud, Fl. de France, vol. i. p. 193. 
This fragrant annual or biennial Stock has such a differ- 
ent appearance from typical M. sinwata, that one would at 
first sight pronounce it a distinct species, and it was de- 
scribed as such by Messrs. Ménier and Viaud-Grand-Marais, 
in the publication cited above, in 1877. Subsequent writers 
have taken a different and probably correct view of its 
status, and there is little doubt that it is a white-flowered 
variety of M. sinuata, differing from the typical or ordinary 
condition in the total absence of a dense, greyish tomen- 
tum. Several other species of plants exhibit the peculiarity 
of densely hairy and glabrous individuals growing inter- 
mixed. Borrichia arborescens, and B. frutescens, also sea- 
coast plants (Composite), inhabiting the West Indies, Florida, 
and Bermuda, are among the most remarkable instances. 
Usually their leaves are clothed all over with hairs or a 
dense, soft down; but side by side with plants thus 
clothed with hairs others occur, having perfectly glabrous, 
glossy foliage. Another species of Matthiola—M. incana, 
Br.—is represented by a variety analogous to the one under 
consideration. At least, that is the view taken by 
Marcu Ist, 1900, *
