Description

The species is varies in sizes up to 1.7 metres and 2.0 metres in diameter, with many branches on a single main stem. The habit of the shrub is dense and rounded. The plant displays pink to reddish purple flowers, during a period from October to January. These are crowded and erect, in a corymbose arrangement that cover the rounded shrub in blooms. Long cilia form a fringe on each flower, this gives the plant a wooly appearance.
The leaves are long and thin, coming to a point, and are sharply triangular and ridged in outline. The length is between 7 and 20 mm long. Floral leaves are similar to those found on the stem.

. The soil types preferred by this section also include red loam and grey sand.

George transferred the botanical name Verticordia callitricha of Meisner's description to a new taxon Verticordia monadelpha var. callitricha.
This variety is between 0.3 to 0.6 metres, or up to 1.7 metres, rounded, but greater in height than width. The plant sometimes attains a size over 1.3 metres tall and 1.2 metres in width.
The distribution is restricted to an area north of Geraldton. This range is bounded by the Emu Proof Fence in the north, and is found in the Kalbarri National Park
