solanum morphology II

the leaf in the top photo is on an early blue plant and the second photo is a wild potato...even though the leaves cluster differently on the stem it is easy to see a physical resemblance between the two...at least some heritable characteristics at work here...the third photo is of a yema de huevo leaf and comparing it to the fourth photo of a wild potato the difference is as plain as the previous likeness...until recently yema de huevos were classified as soalnum phureja rather than solanum tuberosum and that may exalain part of the pronounced morphological differences.
