# 10 is a Sprinthes Spp. Ladies Tresses Orchid.

6 is skunk cabbage

5 looks like I. sanguineum.
11 Thalictrum (possibly T. occidentale) and Ranunculus.

5 Iris setosa

The leaves of 2 look like Circaea.
#3 could be Lathyrus japonicus or Lathyrus venosus.

#3 is a Vicia, but I don't know which one. Vicia americana looks like that, but I'm sure there are other Vicia in Alaska that I'm not familiar with.

#1 is Geum canadense, White Avens

#9 could be a Potentilla but the picture isn't sharp enough for a positive ID.

#1 - Tiarella trifoliata, I think, you can see the seed pods.
#2 - Circaea alpina
#3 - checked USDA Plants and agree with paalexan, Vicia americana
#4 - Ligusticum sp.
#5 - Iris setosa
#6 - Lysichiton americanus
#7 - Ranunculus sp.
#8 - fungi
#9 - Geum, I think, or maybe Potentilla?
#10 - could very well be a Spiranthes, if so it's S. romanzoffiana.
#11 - impossible to positively identify from the picture, but going by the number of seeds I'd say T. sparsiflorum.

8. Dog Lichen (Peltigera sp.)
