Shrub 0-6-1-2 m tall, with branches spreading or pendulous, ± frondose ? Stems 4-lined and ancipitous when young, eventually unlined and compressed; internodes 1-3 • 5 mm long, shorter than leaves; bark greyish-brown. Leaves sessile or subsessile; lamina 10-14 x 3-5 mm, elliptic to elliptic-oblong, acute to subacute-apiculate, margin plane, base cuneate, discolorous, glaucous beneath, coriaceous; venation: 2-3 pairs of looping main laterals without other midrib branches or tertiary reticu- lum; laminar glands short streaks and dots; ventral glands dense. Inflorescence 1-flowered; pedicels 5-6 mm long; bracts deciduous. Flowers not seen. Sepals 5-8 x 1-5-2 mm, free, not imbricate ?, subequal, spreading in fruit, linear-elliptic, acute, with margin entire or minutely denticulate below apex; midrib visible, veins not prominent; laminar glands 4-6, linear, punctiform and ± numerous distally. Petals, stamen fascicles and ovary not seen; styles (in fruit) 3-5^ mm long; stigmas small. Capsule 8-11 x 5-5-5 mm, ellipsoid-ovoid. Seeds dark reddish-brown, c. 0-8 mm long, narrowly cylindric, very narrowly carinate or not, very shallowly linear- foveolate. 2n = ? On cliff faces and steep rocky slopes; 2100 m.

Despite the absence as yet of flowering specimens, it is possible to see H. sherriffii as a relative of H. podocarpoides, smaller in all its parts and with cuneate leaf-bases, narrower sepals and solitary flowers.
