Proteaceae

Leathery, often needle-like or deeply divided leaves on southern-hemisphere shrubs and trees; flowers lack separate petals, instead showing four tepals fused at the base with stamens attached directly to them, clustered into dense, showy heads or spikes often surrounded by colourful bracts.

Many species grow in nutrient-poor soils and compensate with dense mats of fine 'proteoid' roots that dramatically increase nutrient uptake, rather than relying on rich soil.
