Here are some more images of pressed flowers. They probably come from the Prince George / Summit Lake area in BC.
Daniel please write here what you think - Plant 1 - maybe the original collector found some Ocean Spray which isn’t Prince George but maybe fr a trip to Vanc Island east coast? Or the Charlottes ? Plant 2 - I first thought some sort of lady slipper / orchid because of the dried white petal and its shape .... but the leaves? There is a leaf shape (and distinct edge serration) like that on a pink wild orchid Plant 3 - I call Vetch (pea family) - i’d normally think of it along the driftwood beaches of Georgia Strait ocean - and I think I’ve seen it on Haida Gwaii (Queen Charlottes)
PLANT 1 - Yes I agree - grass ... I’m not good at ident native grasses One I really like in Okanagan is “needle and thread grass” Of course we like the native bunched fescue w its grey blue color
In addition to the classic old Lewis Clark native plant books (now avail thru venerable Harbour Publishing in Pender Harbour BC) I’d also look for the good paperback books by Lone Pine - often these books are in museum / national park gift shops or on B.C. Ferries I think (newsstand ) There is a whole list of Lone Pine books so look for THE one specific to your interest and zone (I’m not connected to any of the book companies)
