Leather flower clematis. Clematis pitcheri, perhaps?
On margins of coastal forest
Flowering in coastal scrub on hillside
I'm getting confused by Clematis: this one has large leaves. Is it foetida?
Eagle's T&S came to the rescue and all is clear now.
On floor of willow swamp-forest that is in the process of being restored. Trees being killed- so patchy light rather than a complete closed canopy. Also near young carex secta, geminate and some blechnum fluviatale.
