Flowering bush in HI

I need some help identifying this flowering bush in Hawaii.

 

Could you show how the flowers are attached to the branch of the shrub?

 

Does this help? Sorry I don’t have a picture of the original bush.

 

Freycinetia. Here are some names to check out:

Freycinetia cumingiana: Freycinetia cumingiana Gaudichaud-Beaupré

Freycinetia multiflora: Freycinetia multiflora {Pandanaceae} Climbing Pandanus

Freycinetia arborea: Hawaii's Flowers Are As Intricate And Alluring As Their Names | HuffPost
I see a Hawaiian name for this: 'Ie 'ie.

 

Looking at the Freycinetia photos posted by Forest and Kim Starr (Search: freycinetia | Flickr), I would guess it to be F. cumingiana.

 

Thank you so very much for the quick and thorough reply. It is people like you that help make the UBC forums such an excellent resource !!!
