These were flowering or had just finished flowering. The closer to the base of the plant (aka the older the leaves got), the more rounded the overall shape of the leaves got. I wonder why that is?

Description

for context, please see daily account for Carkeek Park on 4/8. the largeleaf avens was an extremely common plant in the understory of the areas i was walking around the park. there was also a lot of stinky bob and what i think was bracken fern (and maybe some lady fern) characterizing the understory as well. the largeleaf avens was not flowering at this time.

Description

Cute little flower that has a silky coated touch to it. I think it is interesting how some face straight up to the sky (like the one deep in the photo) and how others face sideways (like the one in the front).

Description

This forb was found along the trail in moderate occurrence. The western colt's foot was far more abundant, but of course, I don't know what this one is or if it's invasive. The flowers has rounded petals and also small round spiked orbs-i'm guessing this will turn into a flower. I made a sketch of the orb in my field notebook.

These were growing near the forest as well in a patch closer to the ground, and there were a few yellow flowers visible.
