Common name: Bottle Brush Species name: //Callistemon// //citrinus// Family: Myrtaceae Distribution: Most bottle brushes occur East and South of australia. Two species occur in the South West of WA and four species in New Caledonia.

Can be found growing from Australia's tropical North to the temperate South. They often grow in damp or wet conditions e.g. creek beds, areas which are prone to flooding Highly attractive to nectar feeding birds Source: www.anbg.gov.au/callistemon/index.html

Stamen length: approx. 15mm

Flowers: large and red. The petals are actually quite small, while the stamens and stigma are the main attraction part of the flower being overly excessive in length. This morphology is contrasted to flowers such as roses which have large petals and short stigma and stamens. This inverse in morphology allows a greater general access to pollen transmission vectors both biotic and abiotic since the pollen head is not shielded by petals.

Fruit: Each flower produces a small woody fruit containing hundreds of tiny seeds. These fruits form in clusters along the stem, and are usually held on the plant for many years. The seeds are usually not released from the fruits for several years, but in some species the fruits open after about a year. Fire also stimulates the opening of the fruits in some bottlebrushes.

Pollen: shape of a triangle, not very abundant

Ovaries are contained within the caylx tube. Right: Image showing the male parts of the flower consisting of the stamen and the anthers
