Position of a flower (5)
I believe the answer is:
lotus
I believe this clue is a double definition.
'position' is the first definition.
(lotus is a yoga position)
'flower?' is the second definition.
(I know that Lotus is a type of flower)
'of a' is the link.
(Other definitions for lotus that I've seen before include "Plant that mythically induces languor" , "Cross-legged position adopted in yoga" , "Sacred waterlily" , "In myth, a plant whose fruit induced forgetfulness" , "Exotic flower" .)
