Coast Redwood Plants Part 2

I'm doing a project on coast redwood communities in Santa Cruz County, CA, but am having difficulty identifying a few of the plants I observed out in the field. Any help would be greatly appreciated!

 

Middle picture is Drymocallis glandulosa

 

# 1 The leaves remind me of Veratrum viride

 

I think #1 is probably not Veratrum given the habitat, but likely something similar.

Petioles look reddish and opposite on #3, likely a young Acer.

 

1. Epipactis sp.

 

*snap* Held back from suggesting Orchidaceae for the first, but yes, Epipactis is a likely culprit.

 

I agree.
