4d: Headmaster's put in order for this plant shed (6).
The answer is Retama
Headmaster put in order could be retama shed.
My problem is, I thought the Ximenean rule, to ensure fair play was you could break up a clue into
clue definition OR definition clue
Which would mean you were looking for a word meaning headmaster, shed or possibly plant shed.
I easily got the answer because the barred grid format left R?TAMA, but I think the clue is unfair.
Any thoughts?
