Q. On which type of Basis you classify the plants?

Linnaeus mainly employed the characters of stamens and carpels and that is why the system is called as Sexual system of classification. Further- he took into account the number of stamens for classification and so the system is also named as numerical classification. The basis of classification proposed by Linnaeus are as under:

i) Number of Stamens                                                     (I-XI1 classes)

ii) Size of Stamen                                                          (XIV-XV classes)

iii) Cohesion of filaments into bundles                                (XVI-XVIII)

iv)  Cohesion of anthers                                                  (XIx)

v) Stamens adnate to ovary                                            (xx)

vi) Distribution of sex in plants                                         (XXI-XXIII)

vii) Plant without flower                                                 (XxIv)
