48b. Daviesia mimosoides Brown (1811: 20) subsp. acris Crisp (1991a: 276) , Jeanes (1996: 760), Crisp (2002: 525). Type: Australian Capital Territory, Brindabella Range, summit of Mt Coree, 35°18’S, 148°48’E, 1420 m elev., M.D. Crisp 1909, 18 January 1976. Holotype: CBG; isotypes: AD, NSW

Phyllodes obovate or elliptic, scarcely narrow, rounded or obtuse at apex, occasionally acute, obscurely crenate, basally cuneate, glaucescent. ( Fig. 48D, E ).

Distribution:— Subsp. acris occurs in the Southern Tablelands of New South Wales, the Australian Capital Territory and the eastern highlands of Victoria.

Habitat:— This subspecies is restricted to rocky peaks and ridges above 1200 m elevation. Associated vegetation includes sclerophyll forest but is more usually sparse shrubberies. Although appearing to be an altitudinal cline-form of subsp. mimosoides (above), the rocky substrate and exposed topography seem to be equally important in delimiting the niche of subsp. acris . Populations of subsp. mimosoides occur at similar elevations on more favourable sites e.g. on the upper slopes of the Brindabella Range.

Conservation status:— National: Not listed. Vic.: Rare in Victoria but not considered otherwise threatened— the subspecies occurs more extensively in NSW.
