Two sets of paired flowers, the top one mature, and the lower one, having been pollinated, is starting to develop seeds, inside the hairy tufted ovaries. You can see where the ovary is located (deep withing the flower), in this comparison shot. What is less obvious is that the pollen grains (from another flower) must grow (literally) down the full length of a tube within the style (no longer called a pollen presenter, once it starts to function as the female organ). We tend not to think of pollen as a living organism. But when you see the journey the "germ" must make, (the pollen does not fall down an empty tube), you realise it must literally grow down the full length of the style, to reach the ovaries, within that bulbous bit at the base of the style. Quite a remarkable journey, really.
Two more comments to make. I mentioned when discussing Waratah flowers, that the botanists class them with the Grevilleas, because of the "paired flowers". This is what I mean. Within the composite flower head (truss of flowers), the flowers are arranged in pairs.
