Information
Upright, polycarpic plant to 7 m tall, with trunk to 35 cm in diameter; pith to 4 cm in diameter; stem with densely packed leaf-rosettes of 25–75 leaves, with no internode elongation, cloaked with marcescent foliage or at least covered with retained leaf-bases for 1–3 m below the leaf-rosettes. Infrequent reproduction yields sparsely branched, spreading plants that rarely exceed four reproductive cycles. Leaf lamina oblanceolate, to 78 cm long and 21 cm wide, hair cushion present on upper leaf-base, sometimes extending along upper midvein, lower surface glabrous or with a sparse to dense pubescence, villose along lower midvein. Inflorescence broadly pyramidal to 120 cm tall, 80 cm in diameter; capitula presented horizontally. Ray florets 6–17; to 20 mm long; disc florets 20–90.

Notes
USES. None recorded on specimens from our area CONSERVATION Protected in the National Park; least concern (LC) There is considerable variation in leaf morphology throughout the elevation range on Nyandarua/Aberdares, with plants from the lower elevations having smaller, less pubescent leaves. Additionally, the leaf of Schmitt 692 has a cordate lamina and is constricted below to form a pseudo-petiole, but otherwise conforms to D. battiscombei.
