Rashida ji, I have the booklet that you referred to. It is small enough to carry but the key branches are too long to follow from page to page, the number of families are too many to remember and the keys are often based on disseccted parts seen under microscope. This is yet the most useful key but can be used for herbarium specimens in a laboratory. We need to reduce number of families and have keys relating to field characters. Regards,
