  1. Androecium structure

  2. Flower arrangements

  3. Leaf morphology

  4. Plant habit
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Linnaeus’s artificial system of classification was based on the androecium structure. The significance of flower and fruit structures was first recognized by him. He emphasized the basic numerical characteristics of sexual parts i.e., stamens and carpels. Thus the Linnaeus system is also known as a sexual system.

So the answer is 'Androecium structure'.
