Form of lacy cross often found on a tomato (5)
I believe the answer is:
calyx
'a tomato' is the definition.
The definition and answer can be both plants as well as being singular nouns.
Maybe there's a link between them I don't understand?
'form of lacy cross often found on' is the wordplay.
'form of' indicates anagramming the letters (the letters need to be in another 'form').
'cross often' becomes 'x' (X is cross-shaped. I am not sure about the 'often' bit.).
'found on' means one lot of letters go next to another.
'lacy' with letters rearranged gives 'caly'.
'caly'+'x'='CALYX'
Can you help me to learn more?
(Other definitions for calyx that I've seen before include "Group of sepals" , "Sepals of a flower" , "buddy protection" , "Sepals collectively" , "Protective layer around flower bud" .)
