Botany picture #131: Acacia verticillata

Acacia verticillata (Fabaceae), Tasmania, 2013. Like many Australian Acacias, this one has reduced its ancestrally bipinnate leaves to phyllodes which are merely flattened and expanded petioles. While the diversity in phyllode morphology is stunning, the diversity in flowers and inflorescences in this large genus surely isn't. Basically, they come in yellow and (more rarely) white and in round heads or (more rarely, as in the present case) elongated spikes.
