Shape ovate

A leaf is ovate if it is widest in the most basal third of the lamina (Figures BQ - BU). Figure BR shows a leaf on the boundary between ovate and elliptic. Often leaves will be close to category boundaries and personal judgement is used to categorise the leaf. This is not something to worry about as the numerous other characters across all the species ensures that only small "errors" arise from the occasional mis-categorisation.
