Etymology:
The genus “Pectis” (Pec'tis:) is from the Greek pecteo, “to comb,” the leaves of most species being pectinately ciliate, that is, fringed with hairs on the margin with narrowly close set divisions like the teeth of a comb.

The genus Pectis was published by Carl Linnaeus, (1707-1778) in 1753.

The species epithet filipes (fil'ipes:) from the prefix fili- meaning “threadlike” and pes, Latin for “foot,” hence “with threadlike stalks.”
