Pass on grand slips or bloomers (11)
I believe the answer is:
snapdragons
'bloomers' is the definition.
(I've seen this before)
'pass on grand slips' is the wordplay.
'slips' is an anagram indicator.
'pass'+'on'+'grand'='passongrand'
'passongrand' with letters rearranged gives 'SNAPDRAGONS'.
'or' is the link.
(Other definitions for snapdragons that I've seen before include "bloomers" , "Flowers" .)
