Protea roupelliae subsp. roupelliae flowerhead and leaves

The perianths of individual florets in a Protea roupelliae subsp. roupelliae flowerhead are straight or slightly incurved, the tubes quadrangular, ridged and about 15 mm long. There are only three stamens inside the segment tips of each perianth, the outer segment ending in a staminode.

The about cylindrical style curves in, up to 65 mm long. It can clearly only be housed in a perianth as long as it is quite underdeveloped. At the style tip the linear pollen presenter continues about straight but abruptly bent at its base. The pollen presenters are more colourful than the styles.

The fruit is a hairy nutlet.

The heads soon appear somewhat unkempt after the bud phase with styles escaping from perianths and related events. The spoon-shaped bracts of the upper rows, sparsely arranged, don't hold much private inside the heads due to their narrow lower parts.

The flat to incurving leaf blades in picture are silvery hairy, their tips pointed. They grow at stem-tips up to the flowerhead and may curve up but do not exceed the flowerheads. (Coates Palgrave, 2002; Rebelo, 1995; Pooley, 1993; Rourke, 1980; iNaturalist).
