Constants for Shrubs 



1 Species are grouped primarily according to growth forms, as discussed 

 in the paper. For convenience of reference they are alphabetically arranged 

 under each growth form. The number in parentheses shows the number of 

 individual determinations averaged to obtain the species constant. Those 

 without numbers represent one determination only.
