Extract

The preceding papers of this series have demonstrated (1) that there is a progressive increase of average Dp‐age in the subdivisions of Compositæ which can be correlated with geological age as determined from other data (Small and Johnston, 1937); (2) that these Dp‐ages, when placed on a time‐scale of years, follow a peculiar exponential curve, called the BAT curve (Small, 1937, Q.E. II); (3) that the measure of age in years which is given by the BAT curve can be used successfully for the Grasses (Small, 1937, Q.E. III).
