Taxonomy and naming
Verticordia polytricha was first formally described by George Bentham in 1859 from a specimen collected by Augustus Oldfield and the description was published in Flora Australiensis. The specific epithet is derived from the Ancient Greek words poly meaning "many" and thrix meaning "hair" referring to the hairs on the sepals.In his review of the genus in 1991, Alex George placed this species in subgenus Verticordia, section Corymbiformis along with V. densiflora, V. brownii, V. eriocephala and V. capillaris.
