Description
This species is from Western Australia. Mainly in the Darling Range district with inland occurrences in the Wyalkatchem-Kellerberrin district. It is recorded as occurring in low scrubland, heathland with mallee, Jarrah woodland-forest, swamp flats, open shrubland, on lateritic clay over granite, and sand over granite with quartzite. The species epithet is from the Latin parvus, little, small, and -ceps, from caput, head, in reference to the small inflorescences in the type collection.

Botanical Description
It is a shrub from 0,3-1,2m tall. The branchlets are glabrescent, more or less sericeous.

The leaves are alternate, 7,5-25mm long, 0,7-1,2mm wide, 10-27 times as long as wide, subsessile to rarely short-petiolate. The blade is glabrescent, with more or less sericeous hairs overlaid with longer pubescent hairs, linear to linear-obovate. The base is parallel, the apex is acuminate or acute to obtuse. The 3 veins are longitudinal. The oil glands are moderately dense, obscure to distinct, scattered.

The inflorescences are capitate or shortly spicate, pseudoterminal and sometimes also upper axillary, with 2-8 triads, up to 25mm wide. The hypanthium is hairy, 1,5-2,5mm long. The calyx lobes are abaxially glabrous or very rarely hairy, 0,5-1,5mm long, scarious throughout. The petals are caducous, 1,7-3mm long. There are 6-10 stamens per bundle. The filaments are pink, mauve, purple, rose-pink, magenta or mauve-pink, 8-12,5mm long. The bundle claw is 3-5,2mm long, 0,3-0,5 times as long as the filaments. The style is 10-14,5mm long.

The infructescences are peg-fruited. The fruit is 2,5-3,5mm long. The calyx lobes are weathering away or rarely weakly developed sepaline teeth occur. The cotyledons are obvolute.

Medicinal plant
This species gives a predominantly monoterpenoid oil. The principal monoterpene encountered is linalool (41,2%). This is accompanied by lesser amounts of a-pinene (7%), ß-pinene (17%), limonene (1,6%) and a-terpineol (1,2%). The main sesquiterpenes encountered are globulol (5%), bicyclogermacrene (2%), viridiflorol (2%), spathulenol (4,3%) and cubeban-11-ol (1,3%).
