What is the major disadvantage of using indented key?

Dear Student,

The major disadvantages of Indented keys are:


Indented keys have the two leads of each couplets separated by the couplets following the first lead that makes it difficult to compare with the alternatives.

There is wastage of paper because the keys utilize the right size of the page and so they are expensive to print.

They are called Yoked keys and do not print taxa.
