This genus has been distinguished by a name 
founded on dens, a tooth, in allusion to the tooth- 
like scales of its roots. 
About twenty species of Dentaria are known to 
botanists, chiefly natives of Europe and North 
America ; one only belonging to England, and 
that one more nearly related to the present species 
than to any other; but differing from all in a 
remarkable circumstance, namely, that it is bulb- 
bearing at the axils of its leaves, hence it is ealled 
Dentaria bulbiferum. From these bulbs it may be 
propagated, and as a curious and scarce English 
plant, we hope ere long to give a figure of it. Mr. 
Baxter mentions it as perfectly naturalized in the 
Oxford Botanic Garden. 
Dentaria pinnata is found plentifully in shady 
places, in some parts of France, of Italy, and Swit- 
zerland, but not in the more northern parts of 
Europe. 
The habit of this plant is very similar to that of 
our English species, and will succeed under the 
same treatment. A light soil, in a shady situation, 
will not fail to encourage its growth
