Tropical creeper (5)
![Ross](/clue/static/ross-mug.min.png)
'tropical creeper' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for liana that I've seen before include "Woody climbing (usually tropical) plant" , "Climbing-plant" , "Woody climbing tropical plant -- a nail (anag)" , "Rainforest climber" , "Jungle climber" .)
(Another definition for lantana that I've seen is " Plant".)
