Related to screwpines, the climbing-pandanus (Freycinetia) lacks a rigid stem and uses trees and boulders for support. One species, the widespread F. excelsa, is common on my property.
I am hoping they will flower soon. So, I suspect, are the catbirds, which love the fruit that follows. (Not that there's a dearth of nosh at this place. I'm surprised the quandongs haven't fallen over under the weight of their fruit.)
