Characteristics

A compact, rounded shrub or small tree, 1.5-3 m in height (very rarely attaining 5 m) with a short main trunk 100-400 mm in diam. Stems 8-10 mm in diam., initially covered with a fine indumentum of densely crisped cinereous hairs becoming glabrescent to glabrous with age. Leaves oblanceolate to broadly oblanceolate, 120-250 mm long, 20-50 mm wide, tapering to a distinct petiolar region, 10-15 mm long, apices obtuse to rounded; very heavily coriaceous; covered with a fine crisped indumentum initially, soon glabrous, becoming glaucous or shiny olivaceous with age; margins horny, yellow to red, midrib prominent. Inflorescence broadly oblong-obconic, 70-130 mm long. Receptacle conic-depressed to convex 20-40 mm in diam. Involucral bracts 5-6 seriate; outer series ovate-acute, 10-30 mm long, outer surface sericeous, margins densely ciliate, apices broadly crinite with silvery or purple-brown pubescence; inner series narrowly oblong-obtuse to prominently spathulate, 60-100 mm long, 3-10 mm wide, outer surface sericeous, margins ciliate with silvery or purple-brown hairs, apices bearing a tufted beard of silvery or purple-brown hairs. Perianth straight, 65-90 mm long; tube 12 mm long, externally ridged, glabrous for the most part but sparsely sericeous distally and densely sericeous on outer lip; claws slender to filiform, 35-55 mm long, densely silvery velutinous; limbs linear 20-35 mm long, apices acuminate to prominently aristate, often coiled, thickly tomentose with white and purple-brown trichomes intermixed, particularly on the central flowers in the inflorescence. Anthers 3, on perianth sheath; anther on free perianth limb reduced to a staminode. Style 55-65 mm long, ancipitous, tapering terminally, puberulous in lower half becoming glabrescent to glabrous terminally. Pollen presenter 7-12 mm long, prominently geniculate at style junction, filiform-linear terminally. Ovary obconic 5 mm long, covered with long straight, tawny trichomes. Hypogynous scales narrowly ovate, acute, 2 mm long. Primarily an autumn and early winter flowering species, P. lorifolia is at its peak between mid-April and June although odd flower-heads continue to open up until October.
