Common name:                Bottlebrush

Conservation status:  some are poorly known

• Some species of Beaufortia are common within their range but several, including Beaufortia bicolor, are classified as "Priority Three" by the Western Australian Government Department of Parks and Wildlife, meaning that they are poorly known and known from only a few locations but are not under imminent threat

Etymology:   

• The genus was named for the English gardener and botanist Mary Somerset, Duchess of Beaufort, who possessed a flourishing botanical garden at her seat, at Badminton, in Gloucestershire

Flowers:                  

• Most are andromonoecious, meaning they have both male and bisexual flowers on one plant

• The flowers are in spikelike or headlike inflorescences

• The flower has five triangular sepals and five white, yellow, red, pink, or purple petals, which are sometimes hairy

• The petals usually fall off as the flower opens, or shortly after that

• The stamens are red or deep pink, arranged in five bundles and extend well beyond the petals, giving the inflorescence its colour

• Unlike other closely related genera such as Melaleuca, the anthers are attached to the filament at their base and release their pollen through two curved slits on the other end

• Flowering in most species occurs throughout the year but mostly between late spring and autumn

Fruit: 

• The fruit is a dehiscent capsule with three valves, each holding a winged seed                        

Leaves:         

Stem & branches: 

Roots:         

Habit:        

• Evergreen shrubs with very small, glandular, aromatic leaves usually oppositely arranged

• The tallest are up to 3 m in height

Habitat:   

• Beaufortias are often found in sand plain and in heath, although Beaufortia sparsa usually grows in marshy places and is known by the common name swamp bottlebrush

Distribution:                  

• All species of Beaufortia occur in the South West Botanical Province and about half the species also occur in the Eremaean province

Species:                     

• World:           22

• Australia:     22

Additional notes:   

• Taxonomy 

  • The first formal description of the genus Beaufortia was published in 1812 by Robert Brown in William Aiton's Hortus Kewensis

  • It was followed by a description of the first-named species, Beaufortia decussata

  • Some taxonomists have suggested that Beaufortia along with Calothamnus, Conothamnus, Eremaea, Lamarchea, Petraeomyrtus, Phymatocarpus and Regelia should be included in the genus Melaleuca but the change has not been adopted by most herbaria

• Ecology

  • Most beaufortias are serotinous, only reproducing from seed, released from the fruit after fire

  • Several species which occur in areas where fire is frequent, have a lignotuber which resprouts after fire. Honeyeaters (Family Meliphagidae) and the honey possum (Tarsipes rostratus) are thought to be the main pollinators but many kinds of insect have also been recorded on beaufortia flowers

• Use in cultivation

  • All the species of Beaufortia are worth trialling in the garden but few have been grown successfully in eastern Australia

  • They require full sun and excellent drainage and benefit from being grown over limestone

  • Grafting onto Kunzea ambigua may also improve the chance of success
