A glasshouse study was undertaken to assess the competitive ability of A. lappacea in relation to that of Iseilema spp. and also that of the summer, annual forb Hibiscus trionum (Bladder ketmia). Astrebla lappacea was equally competitive with H. trionum but more competitive than Iseilema spp. However, it is concluded that, in the field, the recruitment of Astrebla spp. may be restricted by high densities of Iseilema spp. It is unlikely that the density of summer forb species are sufficient to restrict Astrebla spp.
