Western Clematis

This plant climbs on bushes and trees for support. It belongs to the Crowfoot or Buttercup family. For some strange reason, I can never get a really sharp photo of the flowers :) It was seen at the Erlton/Roxborough Natural Area. A naturalist states that "This is the richest botanical area in the city, with over 380 species on about 3 hectares of land. However, 80 non-native species are now dominating the area."
