easily recognized but not easily defined, as all 

 the divisions with permanent root-L. contain 

 species in which the stem might be thought 

 scape-like. This is the only division in which 

 we find runners. The L. in most of the species 

 are fiu-nished with a stellate pubescence, which 

 does not extend to the upper surface, while the 

 strong rough hairs are more abundant on the 

 upper surface. The colour is greyish, and 

 some which are described as green are rather 

 comparatively than absolutely so.
