Unadorned; steppe (5)
I believe the answer is:
plain
I believe this clue is a double definition.
'unadorned' is the first definition.
(associated in meaning)
'steppe' is the second definition.
(I've seen this in another clue)
(Other definitions for plain that I've seen before include "Simple, unadorned" , "Not complicated" , "Treeless expanse" , "lament" , "Basic" .)
