Adenanthos obovatus- Basket flower

Adenanthos is a genus of Australian native shrubs in the family Proteaceae. Its centre of diversity is southwest Western Australia. Adenanthos obovatus is commonly known as basket flower or jugflower. Each flower consists of four united tepals and a single style. In the earlier flowering stage both the style-end and the anthers are trapped within the perianth tube, so that when the anthers release their pollen, the pollen adheres to the style-end. Shortly after pollen release, the tips of the tepals separate, causing the tube to break apart. When the style-end is released, the style springs erect, and the flower's pollen is thus held on the style-end from where it may be deposited on the face of pollinators like honeyeaters which can access the nectar with their long curved bills. The apex of the style, called the stigma in most flowering plants, is often referred to as the style-end in Proteaceae, since it performs two distinct functions: it performs the usual stigmatic role of pollen-collector, but also functions as a pollen-presenter. I was quite surprised to learn that.
