Magnolia or sequoia (4)
I believe the answer is:
tree
I believe this clue is a double definition.
'magnolia' is the first definition.
(thesaurus)
'sequoia' is the second definition.

(Other definitions for tree that I've seen before include "famous actor" , "Chestnut or elm?" , "Plane perhaps" , "Genealogy chart" , "Care for shoes" .)
