Characteristics

Slender, sparsely branched, woody shrub, 1-3 m high; mature parts green, not glaucous. Stems usually branched at the base, usually slender and leafless except for the upper parts of plant. Leaves relatively uniform; basal leaves biternate with toothed leaflets; upper leaves junciform, almost invariably totally reduced to the petiole and/or rachis, (59-)121-210(-325) mm long; petiole and rachis adaxially without a groove; lamina totally absent. Inflorescences apical on long shoots, sparse or congested, rarely with only primary racemes, mostly with secondary racemes; lateral racemes terminate in compound umbels, mostly with numerous condensed, sterile scale-leaves; scale-leaves 2-5 mm long; rays (10-)15-26(-46) mm long; involucre bracts (1.0-) 1.2-2.7 (-4.6) mm long; involucel bracts (0.8-)1.0-1.9(-3.1) mm long. Flowers with pedicels (2.5-)3.8-5.4(-6.3) mm long; calyx teeth (0.3-)0.4-0.5(-0.6) mm long; petals very widely ovate, (0.8-) 0.9-1.1(-1.7) x (0.7-)0.91.1(-1.2) mm, inflexed part 0.5-0.7(-0.9) mm long; resin ducts branched; filaments 0.9-1.4(-1.9) mm long, lhe uppermost 0.1(-0.2) mm inflexed in bud; anthers (0.6-1 0.7(-0.8) mm long; ovary (0.8-) 0.9-1.1(-1.4) mm long: stylopodium (0.9-) 1.0-1.5(-1.6) mm wide, (0.3-)0.5-0.7(-0.8) mm high; style (0.1-)0.2(-0.3) mm Fruit widely obovate, with pedicel somewhat intn at the base; mericarps usually tuberculate, (2.2-)3.4-4.8(-5.7) mm long, (1.1-)1.3-1.9(-2.4) mm broad; res'1 ducts (6-) 8-12. Chromosome number: 2n = 22! (voider: Van Wyk 2950).
