First, the cell is the reference source for modelling at any level. Second, developmental signaling occurs between few cells, about 12. Third, rules are algorithmic and not simply physical forces as proposed by Thompson. Finally, it is desirable to propose a likely alternative model that can be discounted. The main value of modelling is selecting more objective data for purposes of modelling rather than that selected by a biased investigator. Keywords: structural hierarchy; plant anatomy; objective data
