Phenology Exercise

The three observations attached to this journal show the differences between flowering and bare plants in the wild. On one hand we have an Oak (needs clear ID though) that has it's leaves yet the California Black Oak is bare. Also included in the bare category is the Cirsium Arvense, a common weed, which is usually found to have little white flowers.
