4.1. OLM  Age or size classification for plants
 

It has been stressed in ChStruct that not even a thorough knowledge of the biology of a species makes it always apparent how to define the relevant i-states. We will take a closer look at this problem here, recalling details of the example already mentioned in the book of two semelparous plant species (Dipsacus sylvestris and Verbascum thapsus) – both classified as biennial but often showing a longer life span in their natural habitats. Individual plants both of these species – have been shown to be adequately qualified on the basis of rosette size in order to predict their fate and the growth of their populations (p. 50).
