Betel-nut source (5)

Ross

I believe the answer is:

areca

'betel-nut source' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for areca that I've seen before include "palm-tree" , "Tall palm tree" , "Palm with red nuts" , "Sort of nut" , "Tropical palm" .)

I've seen this clue in the Thinks.com and the Universal.
