Question

According to Bentham and Hooker's classification the total number of families of non flowering plants are​

Answer 1

Answer:

Bentham and Hooker proposed the natural classification system for seed plants and divide them into three groups, dicotyledons, gymnospermae and monocotyledons. These plants were further divided into three subclasses comprising of 21 series, 25 cohorts, 202 families (including 165 dicots, 34 monocots, and 3 gymnosperm families). He considered gymnosperms as a separate group characterized by the presence of naked ovule and so the gymnosperm families are not included in the real families. So after removal of the 3 gymnosperm families from the total of 202, the real families are 199.
