There are 40 to 70 disk flowers, each three to four millimeters in diameter.

The disk flowers are abruptly expanded at the top.

There are many flower heads (25-80) crowded at the top of the stem, and each head contains four to six yellow disk shaped flowers.

Both the ray and disk flowers are yellow, with one flower head on each flowering stalk.

So, even though they're prettier than the disk flowers, the ray flowers don't have any fun.

The plump yellow or greenish-yellow centers are made up of tiny disk flowers.

Their flowers are either ray flowers or disk flowers.

The disk flowers in the center of the pseudanthium look like the centre of a normal flower.

The radially symmetrical disk flowers are at the end of the branches.

In this genus the disk flowers are actually big enough to be seen as tiny flowers to the naked eye.
