General classfication

I think a general classification based on the following characteristics will be more helpful and easier for those new to botany: 

1. Oshadhis – annual plants.

2. Vanaspatis – trees bearing fruits without evident flowers.

3. Vrikshas – trees bearing flowers and fruits. 

4. Guccha – bushy or shrubby plants.

5. Gulmas – succulent shrubs.

6. Trinas – grasses.

7. Pratnas – procumbent and decumbent herbs.

8. Vallis – twiners.
