Melaleuceae

 Pink bottlebrush Beaufortia schaueri, photographed by Brian Walters.

Belongs within: Myrtaceae.
Contains: Melaleuca.

The Melaleuceae are a group of trees and shrubs bearing clustered flowers and very woody capsular fruits. Members of the genus Callistemon are commonly known as ‘bottlebrushes’ in reference to the cylindrical form of the flower spikes. Callistemon differs from other genera in not having the stamens united into antipetalous fascicles.

Characters (from Wilson et al. 2005): Trees or shrubs; leaves mostly spiral. Inflorescence often a spike-like (an aggregation of solitary flowers or triads commonly called “bottlebrushes”) or head-like clusters of flowers; stamens often fasciculate, anthers fixed or versatile, dehiscing by longitudinal slits, pores or apical slits. Ovary inferior, 3-locular; ovules anatropous or hemitropous. Fruit a very woody capsule, often with delayed dehiscence; seeds linear.
