Protea derive from the name of the Greek god
ProteusIn Greek mythology, Proteus is an early sea-god, one of several deities whom Homer calls the "Old Man of the Sea", whose name suggests the "first" , as protogonos is the "primordial" or the "firstborn". He became the son of Poseidon in the Olympian theogony In Greek mythology, Proteus (Πρωτεύς)...

s are fused to the tepals, in such a way that the anthers are enclosed within the cup. The pistil initially passes along the inside of the perianth tube, so that the stigma too is enclosed within the cup. As the flower develops, the pistil grows rapidly. Since the stigma is trapped, the style must bend to elongate, and eventually it bends so far that it splits the perianth along one seam. The style continues to grow until

, when the nectaries begin to produce nectar. At this time, the perianth splits into its component tepals, the cup splits apart, and the pistil is released to spring more or less upright.

s. Proteoid roots are masses of lateral roots and hairs forming a radial absorptive suface, produced in the leaf litter layer during seasonal growth, and usually shriveling at the end of the growth season. They are an adaptation to growth in poor phosphorus deficient soils, greatly increasing the plants access to scarce water and nutrients by exuding carboxylates that mobilise previously unavailable phosphorus. They also increasing the root's absorption surface but this is a minor feature as it also increases competition for nutrients against its own root clusters. However, this adaptation leaves them highly vulnerable to dieback caused by the
