Description
Summary:Senecio pterophorus DC. is an erect, semilignose shrub (fig. 1) which grows up to 2 m high. Is a chamaephyte basipetal branch-shedder (ORSHAN, Plant pheno-morphological studies in Mediterranean type ecosystems: 210-211. 1989) whose new branches appear below inflorescences but not from the lower parts of the plant. Leaves lanceolate. Stems are annual and develop at their apex a great number of small (up to 15 mm in diameter) yellow capitula which are grouped in a corymbose-paniculated inflorescence (HARVEY & SONDER, Flora Capensis: Cape Colony, Caffraria & Port Natal 3: 386.1865).
