When I am out in the field with plant folks I try to learn a new plant per day. A picture and writing the name helps set the plant in memory. Drawings would be even better.
From a recent outing in Ross Lake National Recreation Area:
Acer glabrum (Douglas maple)
Adenocaulon bicolor (Pathfinder)
Goodyera pubesceus (Rattlesnake plantain). This is a native orchid.
Salix scouleriana (Scouler willow)
The last one has some uncertainty as I did the identification myself.
