Clematis viridiflora Bertol.

A tall climbing shrubby plant; younger stems with short curved hairs but becoming glabrous or nearly so, longitudinally ribbed and furrowed.. Leaves pinnate, with usually 5 leaflets, reduced in association with the inflorescences; leaflets ovate to broadly ovate in general outline, obliquely asymmetric with acuminate lobes with relatively few and large asymmetric (curved) acute teeth, slightly cordate to broadly cuneate, with scattered hairs on lower surface, upper surface nearly glabrous, well formed leaflets 7–12 cm. long and 5–10 cm. broad.. Inflorescences many flowered; pedicels 1–5 cm. long; flower buds broadly ovoid.. Sepals 1.2–1.8 cm. long, cream.. It is possible that several specimens from the coastal region of Tanganyika should be placed in this species. We have, however, not seen material sufficiently well collected for definite determination.
