[edit] Description
An upright plant that can grow to 5 meters (16 feet) tall, with trunk to 20 centimeters (8 inches) in diameter; quite pithy (compared to other Dendrosenecio) with pith 6 centimeters (2.4 inches) in diameter. Stem with a single, densely packed leaf-rosette of 40 to 110 leaves and cloaked with the withered foliage. The leaf-rosette secretes large quantities of a mucilaginous fluid, with the dried mucilage visible on the base of the upper leaf surfaces. Lateral branching starts below the developing inflorescence, but the plants almost never survive the first reproductive cycle. Leaf surfaces are oval with straight tips and can be 58 centimeters (2 feet) long and 20 centimeters (8 inches) wide. Inflorescence narrowly flat topped and can be 220 centimeters (94 inches) tall and 100 centimeters (42 inches) wide. Flower heads are held horizontal each with sixteen to seventeen ray florets and fifty to eighty disc florets.[2]
[edit] Distribution
Dendrosenecio brassiciformis lives on the Aberdare Range between the altitudes of 2,950 and 3,950 meters (9,700 and 13,000 feet).[2]
