Do you see...?
Flowers or flower buds
One or more fresh open or unopened flowers or flower buds are visible on the plant. Include flower buds or inflorescences that are swelling or expanding, but do not include those that are tightly closed and not actively growing (dormant). Also do not include wilted or dried flowers. For Quercus agrifolia, the male inflorescence is a catkin which is initially compact and stiff, but eventually unfolds to become longer and hang loosely from the branch. Female flowers are very small and petal-less, emerging from the growing stem at the point where a new leaf is attached.
How many flowers and flower buds are present? For species in which individual flowers are clustered in flower heads, spikes or catkins (inflorescences), simply estimate the number of flower heads, spikes or catkins and not the number of individual flowers.
Less than 3;3 to 10;11 to 100;101 to 1,000;1,001 to 10,000;More than 10,000 More...
One or more open, fresh flowers are visible on the plant. Flowers are considered "open" when the reproductive parts (male stamens or female pistils) are visible between or within unfolded or open flower parts (petals, floral tubes or sepals). Do not include wilted or dried flowers. For Quercus agrifolia, the male flowers will open once the initially compact catkin has unfolded and is hanging loosely. Female flowers are open when the pistils are visible, but will be very difficult to see where they are out of reach.
What percentage of all fresh flowers (buds plus unopened plus open) on the plant are open? For species in which individual flowers are clustered in flower heads, spikes or catkins (inflorescences), estimate the percentage of all individual flowers that are open.
Less than 5%;5-24%;25-49%;50-74%;75-94%;95% or more More...
One or more flowers on the plant release visible pollen grains when gently shaken or blown into your palm or onto a dark surface.
How much pollen is released?
Little: Only a few grains are released.;Some: Many grains are released.;Lots: A layer of pollen covers your palm, or a cloud of pollen can be seen in the air when the wind blows
