Gelmi and Schulz, in the South Tyrol, observed a purely female form with partly or completely degenerate pollen : the central flowers. Fig. 1(12.

Gelmi states that the styles are always shorter than the ovary in the hermaphrodite flowers, but longer in the purely female ones. The same is true for P. saxifraga. At Ruppin, according 10 Warnstorf, the umbellules of primary umbels bear hermaphrodite flowers; those of secondary umbels
