Characteristics

An erect spreading shrub or small gnarled tree, highly divaricate, 2-3 m tall (occasionally up to 8 m), 2-3 min diam. Trunk or basal branches 100-150 mm in diam., covered with thick, grey, corky to flaking bark. Stems 5-8 mm in diam., very sparsely puberulous to glabrous, soon becoming corky and flaking. Leaves sessile, elliptic to narrowly elliptic, narrowly oblong or sub-falcate, 80-170 mm long, 12-30 mm wide, apices acute; pale greenish-glaucous, glabrous when mature but very sparsely sericeous initially. Inflorescences depressed globose, 50-70 mm in diam., usually terminal and solitary, only very rarely clustered and axillary. Involucral receptacle very broadly conic-depressed, 15-20 mm in diam., 8 mm high. Involucral bracts 5-6 seriate, covered with a fine densely adpressed silvery sericeous indumentum, only very occasionally with rusty-brown margins; outer series very broadly ovate to deltate, 10-15 mm long, 10-20 mm wide, tightly imbricate; inner series widely splayed, oblong-incurved, 30-35 mm long, 5-10 mm wide, apices concave, rounded. Perianth 35-50 mm long, straight in bud glabrous at base of tube only, otherwise densely pubescent; tube inflated, very prominently ridged, glabrous proximally but sparsely fulvously-villous distally, 10-15 mm long; claws broad, prominently veined, fulvously villous, margins undulate; limbs linear, acute, straight, 10-20 mm long, very densely white-sericeous to tomentose, except on median adaxial limb which is glabrescent. Anthers 4, sessile. Style straight, terete, glabrous, 40-60 mm long. Pollen-presenter straight, filiform, swollen at junction with style, 10-12 mm long, minutely bilobed at apex. Ovary obconic, 5 mm long, covered with 10-15 mm long, straight tawny trichomes. Hypogynous scales 1-2 mm long, broadly ovate, fleshy. Flowering is often erratic, differing in time from locality to locality, apparently being very largely dependent on microclimatic factors, particularly the frequency and volume of rainfall. Open flower-heads can be found at almost any time between August and February, in different populations. Some populations seem to be predominantly winter and spring flowering. The almost leafless shrubs are most striking at the end of winter when covered with silvery-white flower-heads. Nevertheless, summer does seem to be the peak of the season, especially from late December until the end of February; corresponding with the rainy period, when P. gaguedi flowers in full foliage.
