Observations of a naturalized Gazania population & fruit morphology of a Baccharis species

Gazania linearis is reported to be naturalized in California (amongst a host of cultivated Gazania hybrids and species), and the fruits of Baccharis salicifolia ssp. salicifolia are reported to have 5 ribs. By carrying out a morphological study of a naturalized Gazania population, and fruits of a B . s . ssp. salicifolia individual, I was able to conclude that G. linearis may not be the only naturalized Gazania species in the population studied here (and perhaps across California), and that the number of ribs on the fruits of B . s . ssp. salicifolia are not restricted to 5, and in fact, vary in numbers.
