This is also an important family of herbs and undershrubs 

 characteristic chiefly of the outer marginal zone, but a few 

 occur in fairly dense shade under the trees. Though the 

 aerial branches are commonly herbaceous many of them have 

 a woody rootstock. They often mix with the numerous Acan- 

 thaccEe, but some of them can withstand drier conditions 

 and more exposure and tend to die back in winter.
