Description
Dendrosenecio elgonensis can grow to 7 meters tall, with a trunk to 30 centimeters in diameter and pith 2.5 to 3 centimeters in diameter. D. elgonensis generally keeps its stem cloaked with its withered and decaying foliage (or with retained leaf-bases after fire) but eventually loses them as bark develops. "Periodic reproduction yields sparsely branched, spreading plants that rarely exceed five reproductive cycles."
Leaf surfaces are elliptic or heart-shaped, 97 centimeters long and 32 centimeters wide. The lower portion of the leaves are hairless except for along the mid-vein.
Flower heads are presented horizontally. 11 to 13, 24 millimeter long ray florets and 40 to 70 disc florets.
Distribution
Found on the slopes of Mount Elgon between 2750–4200 meters.
