Hando's Wattle, or Percy Grant Wattle, is a resinous, slender shrub growing 1-2 m high and 1-2 m wide with sticky bright yellow globular flower heads (Orchard & Wilson 2001).

This species is known from only one population in Barakula SF, N of Chinchilla, Darling Downs District, SE Qld (Halford 1995r; Orchard & Wilson 2001). The site occurs within the Condamine R. catchment and the Brigalow Belt South Biogeographical Region. The single locality encompasses 28 ha, 5 km east of Chinchilla Auburn Rd, on the main fire-break south of Little Hellhole Creek (Halford 1995r; Lithgow 1997). Over the last twenty years, the species has spread over a greater area (Lithgow 1997).

In Dec. 1994, the species was estimated to be represented by 10 080 individuals comprised of 4200 mature and 5880 juvenile plants. No seedlings were observed. The population was distributed over three separate stands. The density of plants varied considerably (Halford 1995r).

This species does not occur in a conservation reserve (Halford 1995r; Briggs & Leigh 1996).

The species grows in lateritic soil of grey sand or clayey silt with ironstone gravel, in gently undulating country. Often on stony ridges (Orchard & Wilson 2001), in eucalypt woodland and open forest (Simmons 1988; Orchard & Wilson 2001).

It occurs near the crests of low rounded hills with gentle slopes, consisting of remnant sandstone, at 420 m asl. The soils are generally infertile, shallow (<40 cm deep), brownish black and stony, with low water holding capacity. The area has a subhumid subtropical climate, with warm to hot, moist summers and cool to cold, dry winters (Halford 1995r).

The species occurs in an open forest with a sparse to dense shrub layer. Dominant trees are Eucalyptus fibrosa subsp. nubila and E. watsoniana subsp. watsoniana. E. tenuipes may be present, especially on hillcrests. Smaller trees include Allocasuarina inophloia and Lysicarpus angustifolius. The lower stratum varies greatly in density and composition but includes Acacia complanata, Dodonaea filifolia, Boronia bipinnata, B. glabra, Cleistochloa subjuncea, Entolasia stricta, Schoenus kennyi, Triodia scariosa subsp. yelarbonensis and Lomandra multiflora subsp. multiflora. No introduced weed species were present in the population (Halford 1995r).

Flowers are borne Jun.-Sept. (Simmons 1988; Lithgow 1997; Orchard & Wilson 2001). Fruit has been observed to mature in Nov. (Halford 1995r).

Seed germination is promoted by heat from fire. Anecdotal evidence suggests the species is usually killed by fire, but some plants will reshoot from the base (Pedley 1981; Halford 1995r). It is a short-lived species that regenerates well from seed (Lithgow 1997).

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.
