The character of the undergrowth and herbaceous vegetation 

 in the forests of the Wicomico Upland depends upon the surface 

 soil conditions, which are in turn dependent upon the stage of re- 

 forestation that has been reached. The subordinate vegetation is 

 divisible into a more xerophilous set characterising the earlier stages 

 of reforestation, in which the soil is more exposed to the sun's 

 rays, and a more hygrophilons set which characterise the shade of 

 the later stages of the forest. 



Among the commonest of the xerophilous set are:
