ABSTRACT
A phytosociological study of a weed community dominated by Hydrocotyle mannii and Centella asiatica was carried out in
Kampala, the capital city of Uganda from 2000 to 2002. The Zurich-Montpellier
School of Phytosociology method was used with special emphasis on floristic and
synecological structure as well as on dynamic aspects. This community was found
to grow on shady moist roadsides and is about 15 cm high. In total, 54 species
were recorded; most of them are annual, anemochorous
and widespread. The Hydrocotyle mannii and Centella asiatica community is
described as a new weed association: Hydocotylo-Centelletum
asiaticae Mosango ass. nova.. Hydrocotyle mannii, Centella asiatica, Dichondra repens and Sida veronicifolia have been recognized
as the character species of this association. The Hydrocotylo-Centelletum is a pioneer association. It has been ascribed to the alliance Eleusinion
indicae Leonard 1950 which includes plant
communities growing on shady roadsides. In terms of ecological succession, it appears to be
evolving to the Asystasia gangetica herbaceous fallow association which belongs to the alliance Panicion maximi. It belongs to the order Ruderali-Euphorbietalia Schmitz 1971 and the class Ruderali-Manihotetea Leonard in Taton 1949.
