The first and second band of the upper series are called respectively ws and pwr.
Two jungle flowers now serve as pwr, one a kind of Ixora, but the botanical name of the other has not been identified.
The rule is that they are borrowed from a ws or pwr pattern, but the special characters must be omitted.
All the figures of the combs, except the ws, pwr, and tn-wg must be of the very simplest kind.
Ws and pwr are the protecting figures, whose charm keeps off the diseases.
The youths who copy the combs overlook this and insert in the neighbouring bands the complete ws and pwr patterns.
