Family:Asteraceae
Scientific Name:Quelchia
Discussion:Pollen grains of Quelchia are easily separable from the above genera by virtue of the greater exine thickness and somewhat more prominent spines. Quelchia barcteata (fig. 94 A, B) is typical for the genus, as indicated by the material available. As shown in table 1, exine thickness and spine length are appreciably greater in Quelchia; in shape, however, the grains are subprolate to prolate sphaeroidal, like those of Stenopadus.
