Label in new seed bed (8)
I believe the answer is:
Here is my best explanation:
'label' is the definition.
'in new seed bed' is the wordplay.
'in' indicates putting letters inside.
'new' indicates an anagram.
'bed' becomes 'crib' (I've seen this before**).
'seed' anagrammed gives 'dese'.
'dese' enclosing 'crib' is 'DESCRIBE'.
(Other definitions for describe that I've seen before include "Depict", "Draw (figure); give account of", "Delineate", "Outline", "Paint in words", "Portray in words", "Represent in words", "Provide image", "Report in detail" and "style".)
