Synonyms: Gymnanthemum myrianthum (Hook.f.) H. Rob.
Vernonia ampla O. Hoffm.
Vernonia podocoma Sch.Bip. ex Vatke
Vernonia stipulacea Klatt
Vernonia subuligera O. Hoffm.
Common names: Eared vernonia (English)
Frequency: Common
Status: Native
Description:
Large shrub or even small, soft wooded tree. Although it can be a "messy" shrub, I (BW) find it quite beautiful when in flower because the large inflorescences turn the whole shrub into a ball of colour varying from white to deep purple.
Notes:
  1. This is an abundantly common species in the Vumba, especially in degraded areas. In the Leopard Rock Game Reserve it has become one of the most dominant pioneers in the former coffee fields (together with Dodonaea angustifolia). It became so "weedy", that at one time it was thought to be an exotic (specifically Bugweed) and, unsuccessful attempts were made to eradicate it.
  2. This indigenous species, which can be a dominating pioneer in secondary vegetation, looks superficially like Solanum mauritianum (Bugweed) as both are tall shrubs with prominent false stipules.
  3. They may be distinguished as follows:
    • Firstly, the flowers and fruit are totally different and if these are present, the species are easily distinguished.
    • When not in flower or fruit, the main differences are:
    • Solanum mauritianum leaves, petioles and small branches are densely tomentose, especially when young. This gives the whole plant a light grey green appearance whereas Vernonia myriantha is a dark green colour.
    • the leaf margins are entire in Solanum mauritianum; serrated in Vernonia myriantha
    • the hairs on Vernonia myriantha (examine with a hand lens) are simple whereas the Solanum mauritianum hairs are stellate.
