Senecio brasiliensis, known by the common name flor-das-almas,[1] (flower-of-souls), is a perennial species of the genus Senecio and family Asteraceae. It is native to fields and meadows of central South America.
Description
S. brasiliensis is a densely leafy perennial herb, 1 metre (3.3 ft) to 2 metres (6.6 ft) tall, with yellow flowers that prefers to make its home in degraded pasture lands and unploughed croplands in central South America.[3][4]
Leaves and stems: S. brasiliensis stands very upright with a branched hairless and grooved stem. The leaves are alternate, pinnate and deeply lobed[4] dark green on the top, whitish green on the underside.[5] The lower part of the plant is smooth, while the upper part is hairy and the leaves cluster at the highest point with the flower stalks (corymbs).[4]
Flowers: Yellow flowers dense on corymbs; two types of flowers (that look like [petal]s), disc florets with both male and female flowers and ray flowers which are simply female.[4]
Seeds: Small seed with white hairs that use the wind to get around with.[4]
