Experiments were performed to evaluate the effects of air pollution on two groups of plants of the genus Lupinus. One group was used as controls and were grown under conditions approximating those in nature. The other group was given variations of temperature and daylength and was treated with filtered smog. The number of plants that survived under each of the different growth conditions was tabulated. The types of damage observed in Lupinus which have been considered as being due to smog varies from mild damage to death. No apparent vegetative damage could be observed on some of the plants, but complete blocking of the floral development, during periods of smog could be detected. On other plants both vegetative damage and the blocking of floral development was observed. It is evident that susceptibility and resistance to smog, within the subspecific taxa of a single species, suggests that the heredity of the plants is involved, giving some of the plants a marked advantage in survival in the Los Angeles area.
