Berula erecta (Huds.) Coville

Weak, glabrous, erect or decumbent rhizomatous perennial, rooting at the lower nodes with clusters of white rootlets, 0.2–1 m. tall, rather sparingly branched from the base upwards.. Stem and branches succulent, fistular, with raised lines and alternating grooves, stems sometimes reddish about the base.. Leaves simply pinnate; lowest leaves with the lamina linear-oblong in outline, ± 5–45 × 3–12 cm.; leaflets in (5–)7–11(–13) pairs, linear to broadly or oblong-lanceolate, 0.7–7.5 × 0.3–2 cm., acute to obtuse at the apex, occasionally incised at the base on the antical margin with a forwardly-directed lobule, margins with jaggedly acute to rather blunt, pale-or whitish-mucronate teeth; sheath oblong, occasionally ciliate, auriculate above, ± 0.6–4 cm.; petiole 2.5–11 cm.; upper leaves rapidly much reduced, sessile on the sheaths, leaflets often very small and sharply toothed, in 2–5 pairs.. Umbels on 1.5–8 cm. peduncles; rays 9–16, usually unequal, 0.7–4 cm.; involucre conspicuous, of ± 5–8 linear and simple to dentate, trisect or pinnatisect, pale-margined bracts; partial umbels ± 7–22-flowered, pedicels 2–4(–6) mm.; involucel similar to the involucre but smaller, entire or sparingly denticulate, subequalling the flowers at anthesis.. Sepals small but obvious, subulate.. Petals white, ± 1 mm.. Fruit broadly ovoid to almost round in outline, ± 2 mm., glabrous, primary ribs pale, narrow; stylopodia shortly conical, exceeded by the rather slender, ± 0.75–1 mm. styles.. Fig. 24.
