Some prefix I attached to the plant (4)
I believe the answer is:
ixia
'the plant' is the definition.
The answer is an example.
'some prefix i attached' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'IXIA' is hidden in the letters of 'prefix i attached'.
'to' is the link.
(Other definitions for ixia that I've seen before include "Iris" , "SA plant" .)
