Stout woody shrub 15 cm. to 1 m. tall, the branches c. 5 mm. diam., closely lfy towards tips. Branchlets with wide bifarious pubescent bands to almost glab., length of internodes us. < diam. except in sheltered places. Lvs ± deflexed, coriac., varying in size, toothing and shape on one stem and also according to habitat, e.g. in garden 5 cm. × 13 mm., narrow elliptic-oblong, on mountain 1·5-2 cm. × 7-9 mm., obovate-spathulate; bases broad and shortly connate, lf-bud without sinus; lamina ± bluntly toothed, sts entire, tip obtuse to quite flat; margin rounded and conspicuously white with tangled soft hairs, shorter hairs us. scattered over upper surface when young.
