ʻAhakea
'Ahakea is hard to tell from Kopiko because both look similar to one another. One way I can tell is that 'Ahakea flowers protrude from the middle of the stem and Kopiko flowers shoot out from the top. 'Ahakea flowers clusters in 2-3 while Kopiko flowers come in up to 12. But if there are no flowers, then it is hard to tell. Kopiko usually has a row of alternating dots under each leaf while 'Ahakea doesn't. One place to find 'Ahakea is on the Wiliwilinui trail.
Background Information
