FAQ
Frequently Asked Questions

No. While it is the Latin word for 'book' (seen in 'library', 'libretto'), in English it is only used for the botanical/historical meaning of inner bark/phloem.
In strict botanical terms, they are synonyms. 'Phloem' is the more common modern scientific term, while 'liber' is sometimes used in a more descriptive or historical sense.
It would be very unusual and confusing. Use 'inner bark' for general descriptions or 'phloem' in a scientific context.
