The Small-flowered Conostylis is a rhizomatous perennial grass-like herb, low growing to 20 cm high, forming tufts to 30 cm in diameter (Hopper et al. 1987).

This species occurs in the Dongara/Irwin/Strawberry area of western WA. It is mainly confined to the southern part of the Geraldton CALM District, with one population also known from the Moora District (Patrick 2001). In the Geraldton District it is found over a range of c. 30 km in an area NE of Dongara, extending S to the boundary of the Geraldton and Moora CALM Districts. Only one population occurs on a nature reserve (Patrick 2001).

In 1997, Holland et al. reported six populations comprising 65 plants (Holland et al. 1997). Patrick (2001) and Patrick & Brown (2001) reported seven populations, most likely including the six populations referred to by Holland et al. (1997) though different locality descriptions and widely different population sizes cited in the different documents make direct correlation impossible.

In 2001 seven populations were reported, comprising over 619 plants, though over 550 of these occur in a single population(Patrick 2001; Patrick & Brown 2001). All populations occurred on narrow road or railway reserves in fragmented, remnant heath vegetation (Holland et al. 1997b).

This species is related to Conostylis teretifolia but has longer leaf hairs, which are confined to the base of the leaf. It flowers earlier and has smaller flowers, arranged in a bifurcate, flattened, many-flowered head, not in a few-flowered simple head (Patrick 2001).

Grows in white or grey sand, usually high in the landscape in heath or low heath. Associated species include Allocasuarina humilis, Eremaea sp., Hakea trifurcata, Hibbertia hypericoides, Dryandra fraseri and Hakea erinacea (Hopper et al. 1987; Holland et al. 1997b; Patrick & Brown 2001; Brown et al. 1998).

The flowers are pale yellowish-cream ageing to brick red (Patrick 2001). Flowering time is July to Aug. (Hopper et al. 1987). The genus consists of a mixture of insect and bird pollinated species, but little is known about the pollination of C. micrantha (Holland et al. 1997b).

The response of this species to fire is unknown, however, it is predicted that, like other species of Conostylis, it will regenerate from subterranean regenerative buds emerging from horizontal rhizomes (Gill 1981 in Holland et al. 1997b) and soil stored seed will germinate following summer fire (Holland et al. 1997b). Germination of soil stored seed may be an important part of this species' lifecycle and be necessary for regeneration. However, inappropriate fire regime may lead to either nil or low seedling recruitment, and high frequency fire may lead to a depletion of the soil seed banks and a temporary increase in the availability of nutrients for weed establishment (Holland et al.1997b).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
