Nodding Thistle Carduus nutans
Order: Asterales. Family: Asteraceae

© nan
Addo Elephant National Park

Description
Mature plants range in height from 1–1.5 m tall and have multi-branched stems. This thistle has sharply spiny stems and leaves. The stem is cottony/hairy. The plants develop a rosette, with large leaves 30–60 cm long. The leaves are dark green, coarsely bipinnately lobed, with a smooth, waxy surface and sharp yellow-brown to whitish spines at the tips of the lobes.They are more or less hairy on top, and wooly on the veins below. The plant bears showy red-purple flowers. The large globose flower heads, containing hundreds of tiny individual flowers, are 3–5 cm diameter and occur at the tips of stems. The flower heads commonly droop to a 90° to 120° angle from the stem when mature, hence the name of "Nodding thistle". Each plant may produce thousands of straw-colored seeds adorned with plume-like bristles. They are 4 to 6 cm across, with purple-red bracts.

Distribution
Native to Europe and Asia. Invasive plant in the Eastern Cape, NEMBA Category 1b. It is now widespread in areas like Grahamstown, Cradock, Kenton-on-Sea, Paterson and Addo.

Habitat
The nodding thistle grows from sea level to an elevation of about 2 500 m. It is found in neutral to acidic soils. It typically grows in meadows and grasslands, heavily grazed areas such as pastures and in disturbed soil such as roadsides and building sites. It spreads rapidly in areas subjected to frequent natural disturbances such as landslides and flooding, but does not grow well in excessively wet, dry or shady conditions.

Rough Ragwort Senecio rigidus
Order: Asterales. Family: Asteraceae

© arks
Along Ou Kaapse Weg, near the entrance to the Silvermine area of TMNP

Description
Robust shrub with roughly hairy stems and leaves. It grows branched stems with rough, hairy and longitudinally lined surfaces, reaching heights around 1.5 m.
The small flowerheads are borne in large branched clusters called corymbs, flattish or shallowly rounded in shape. Flowerheads comprise both disc and ray florets, all yellow. The rays, only five or six in number on each flowerhead, are short, elliptic in shape with longitudinal undulations. The small yellow disc protrudes above the ring of ray florets. The individual flowerhead stalks or pedicels have surface scales; so do the involucres.
Distribution
South African endemic to the Eastern Cape and Western Cape, mainly along the coastal strip, inland in the west to Clanwilliam.

Habitat
