 high with a spreading top; branches light brown thickly covered with small lenticles; 

 leaves ovate-lanceolate, acuminate, 7 cm long, 3 — 5 cm wide, glabrous, biglandular on 

 the nerves near the base or on the 6 — 10 mm long, pubescent petiole; fruiting calyx 

 8-glandular; fruit in terminal or axillary panicles with brown-pubescent peduncles and

 base, the bracts short, ovate, thick and coriaceous. Pedicels 1,5 — 2 cm long, stout, 

 striate, thickened at the summit. Calyx 8-glandular, the glands concave, the sepals
