Characteristics

A large, rounded shrub or tree 3.0-5.0 m in height, 3.0-6.0 m in diam.; crown rounded, rigid due to the very divaricate interlocking branchlets; trunk stout, 5.0-0.0 cm in diam., covered with thick (3.0-5.0 cm) bark, greyish reddish or black with reticulate, horizontal or longitudinal fissures. Flowering stems stout and rigid, 1.0-1.5 cm in diam., covered with a short, dense, whitish to cinereous indumentum of crisped hairs or with a shaggy, villous indumentum of patent, silky trichomes. Leaves sessile, oblong, oblanceolate, broadly elliptic or obovate, 6.0-1.5 cm long, 2.5-5.0 cm wide; apex rounded or acute, obtusely or deeply incised with 3-10 teeth; glabrous, or pubescent with a fine greyish indumentum of short, crisped hairs, margins occasionally fimbriate. Inflorescences globose to ovoid, 7.0-9.0 cm in diam.; pedunculate, peduncle to 1.5 cm long; occasionally solitary but usually in groups of up to 3; often partly enclosed by the uppermost leaves on the shoot. Involucral receptacle conic acute, 2.5-3.0 cm long, 1.0-1.5 cm wide. Involucral bracts ovate acuminate, 1.2-1.5 cm long, 1.0 cm wide, tightly imbricate, cartilaginous, villous to tomentose. Bracteoles obtrullate, apex sharply acuminate, 2.0 cm long, 1.0 cm wide, cartilaginous, clasping perianth; lanate proximally, sericeous distally. Perianth 3.5-5.0 cm long, yellow. Perianth tube 1.0 cm long, cylindric, glabrous. Perianth claws recurved at anthesis, beset with an erect sericeous to very densely sericeous indumentum, except the median adaxial claw which is puberulous to shortly villous. Perianth limbs lanceolate acute, 6.0-8.0 mm long; outer surface closely adpressed sericeous, the median adaxial limb puberulous. Style stout, 1.0-1.5 mm in diam., 4.5-5.5 cm long, adaxially curved at first, later straightening. Pollen presenter broadly conic acute, 4.0-5.0 mm long, 2.0 mm wide. Hypogynous scales lanceolate acute, 2.0 mm long.
