Abstract. Qualitative and quantitative data reported from a 12-acre one year old field composed of two 6-acre strips of diverse history. Frequency and density of angiosperms were recorded from 70-1/2 X 1/4 meter quadrats during July, August, and September of 1965. Seventy-two species and varieties in 57 genera and 28 families are represented in collections from this field. Twenty-six species were recorded from the quadrats sampled, representing 36.1 per cent of the total number collected. Vegetation present during the first year following abondonment was composed primarily of and dominated by annual forbs; dominants included Ambrosia artemisiifolia, Chenapodium leptophyllum, Mollugo verticillata, Convolvulus, and Setaria glauca.
