Encelia densifolia is a species of perennial shrub in the sunflower family commonly known as the Vizcaino encelia. This species is endemic to the Vizcaino Peninsula of Baja California Sur, Mexico.[1]
Description
[edit]Multi−branched perennial shrub, reaching 1–3 feet (0.30–0.91 m) in height. The branches are lined with dentate, triangular leaves a few centimeters long, that are light green, hairless and smooth in texture.[2]
The inflorescence is a solitary daisylike flower head 1–2 inches (2.5–5.1 cm) in diameter, on a short, leaved peduncle. The head has a center of many yellow disc florets surrounded by up to 12 yellow ray florets. The involucre consists of canescent, obtuse phyllaries. It blooms in spring.[2]
The fruit is an achene about half a centimeter long, usually lacking a pappus. The fruits have ciliate margins[2]
Distribution
[edit]The plant is native to Baja California Sur, México, where it is known only from one small, remote arroyo in the Sierra Santa Clara on the Vizcaino Peninsula.[1]
