After sorting, name a certain plant genus (7)
I believe the answer is:
anemone
'plant genus' is the definition.
'anemone' can be an answer for 'plant' (I've seen this before). I am unsure of the 'genus' bit.
'after sorting name a certain' is the wordplay.
'after sorting' indicates anagramming the letters.
'a certain' becomes 'one' (ie one particular example of something).
'name' is an anagram of 'anem'.
'anem'+'one'='ANEMONE'
Can you help me to learn more?
(Other definitions for anemone that I've seen before include "Flower; marine creature" , "Pretty flower or sea animal" , "Bright flower or sea plant" , "Colourful plant of buttercup family" , "Plant of the buttercup family - one name (anag)" .)
