Diplolophium swynnertonii C.Norman

A very robust perennial herb 1-2 m high, often glaucous and sometimes sub-shrubby. Stems arising several together, relatively simple and unbranched, terete, rigid, solid and with distinct rather fine grooves, glabrous to slightly puberulous, often tinged purplish-brown. Leaves glabrous, 2-ternate to pinnate, the lateral leaflets consisting of 3-5 pinnules, while the central leaflets have 2-3 pairs of pinnules, with or without a terminal pinnule. Ultimate divisions 4-6-5 x 1-4 cm, broadly ovate or subrotund to narrowly elliptic, fleshy and somewhat coriaceous, entire with a short mucronate tip, or with the apex cleft into 3 or more teeth. Leaf bases sheathing and auriculate, rather membranous. Juvenile leaves deeply cut with narrow segments or large irregular teeth. Umbels with numerous ± regular rays 3-9 cm long, finely and densely pubescent. Bracts 1-4 x up to 7 mm, very well developed, linear, green with a membranous margin. Bracteoles similar to the bracts, sometimes withering and partially eroded in mature fruiting umbels. Flowers numerous in each partial umbel on finely pubescent, regular rays; petals greenish-white to creamy-yellow. Fruit narrowly elliptic with well-developed, obtuse ribs, densely bristly pubescent, especially before maturity. Stylopodium conical; styles clubbed at the apex, reflexed in fruit. Endosperm semi-circular in section, with blunt projections towards the broad ribs, commissural face flat. Vittae 1 in each interval and 2 in the commissural face. Carpophore entire or 2-cleft nearly to the base.
