This very distinctive species normally produces one single stem up
to 8 m tall and only 10-15 cm thick. Sometimes, plants branch from the base and form large shrubs.
Each stem bears about 25 leaves, up to 90 cm long and grey-green on both sides; the sap is poisonous.
The inflorescences are much-branched, with carmine to reddish-orange flowers.
The species is found in more or less dense bushland and thickets along rivers in
southern Kenya and northern Tanzania at altitudes between 900 and 1500 m.
