      Berries in dense terminal clusters. Globose, densely covered with star-shaped hairs. Become yellow on ripening. They are 

poisonous to man and act as a host for the fruit-fly. Eagerly eaten by birds which disperse the seeds widely (Photo by R. P. Ellis available from - Click for full size   Leaves dull green and velvety above, up to 250 mm long x 100 mm wide; emit a strong smell when bruised (Photo by R. Botha available from - Click for full size   Flowers in compact terminal clusters. The inflorescences are very showy and although declared weeds, these plants are 

sometimes cultivated as ornamentals (Photo by R. Botha available from - Click for full size   Leaves white-felty below, midrib thick and very conspicious (Photo by R. Botha available from - Click for full size   Fruit in compact, branched, terminal clusters (Photo by R. Botha available from - Click for full size   Corolla 5-lobed, lobes spreading and deep purple with a whitish central line. Stamens 5, inserted in corolla-tube; 

filaments much shorter than anthers; anthers large, oblong, dehiscing by longitudinal slits. Style long, terete, with 

capitate stigma (Photo by R. Botha available from - Click for full size   Inflorescence a dense, many flowered, terminal cluster. Note the dense woolly felt covering the sepals and bracts. This 

greyish velvety covering occurs on most parts of the plant and consists of star-shaped hairs. The hairs are easily 

dislodged, toxic and cause respiratory problems in humans (Photo by R. P. Ellis available from - Click for full size   Much-branched and unarmed with relatively large, woolly leaves (Photo by R. Botha available from - Click for full size   Soft wooded perennial shrub or small tree up to 4m high. Large leaves stalked, lower surface densely covered in whitish 

felt, margins smooth. Widespread weed in South Africa, particularly of disturbed wooded areas and along streams, here from 

Pretoria (Photo by R. P. Ellis available from - Click for full size   Typical fruit (a relatively large number of fruit, each containing many seeds, per plant as can be seen from this image) of 

the bugweed plants that provide food for fruit eating birds over a period of time in the summer months, Munster, 

KwaZulu-Natal, South Africa. This allows the for easy dissemination of the seed by the birds and for the rapid 

establishement and spread of this invasive species (Photo by D. C. Nowell available from - Click for full size

    Solanum mauritianum est une mauvaise herbe envahissante largement répandue qui appartient à la famille des solanacées. En peuplements denses, elle peut exclure des plantes indigènes, mais si les peuplements sont clairsemés, elle peut aider des jeunes plantes indigènes à se développer. Toutes les parties de cette plante sont toxiques pour l'homme en particulier les baies. Cette plante est dispersée par les oiseaux, les fruits étant particulièrement appréciés par certaines espèces. Le contrôle biologique de cette espèce a été entrepris en Afrique du Sud.
