Persoonia hindii (a shrub) - endangered species listing
The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list Persoonia hindii P.H. Weston & L.A.S. Johnson, a shrub, as an ENDANGERED SPECIES on Part 1 of Schedule 1 of that Act. Listing of Endangered Species if provided for by Part 2 of the Act.
NSW Scientific Committee - final determination
The Scientific Committee has found that:
1. Persoonia hindii (Proteaceae) was first described by P.H. Weston and L.A.S. Johnson in 1997, from a 1989 collection from the Newnes Plateau, near Lithgow.
2. Persoonia hindii has been described in Telopea 7(3): 199-203, by Weston and Johnson (1997) as: "Erect to spreading, multistemmed, suckering shrub, with extensive, linear, stolon-like rhizomes, which lie about 5 cm below the soil surface, and from which aerial shoots arise at irregular intervals, 0.3-1.0 m high; bark smooth, grey, present only on substantially woody stems. Hairs 0.3-0.8 mm long, greyish, antrorsely appressed to antrorsely spreading. Immature stems moderately hairy, mostly dull red when fresh; internodes 0-6 mm long. Leaves alternate, linear-oblong, acuminate, (0.3-)1.5-2.7 cm long, (0.5-)1.0-2.0 mm wide, succulent, approximately semi-circular in cross-section when fresh, the flat to slightly concave surface being adaxial, rigid and deeply concave when dried, erect but strongly recurved at the base, the lamina spreading and usually slightly incurved, sometimes recurved at the tip, more or less laterally symmetrical, not twisted, sometimes pungent when dried, dull brownish green to mid-green when fresh, grey-green to brown when dried, slightly paler beneath, sparsely hairy when immature, retaining a few hairs towards the base but otherwise glabrescent when mature, smooth; venation obscure. Inflorescences growing from terminal or lateral buds, auxotelic, 1-13 flowered; rachis 0-2.0 cm long; flowers subtended by scale leaves and/or reduced leaves at the base of the inflorescence and by full-sized leaves more distally. Pedicels 2.5-5 mm long, spreading to suberect, moderately hairy, dull red when living. Perianth actinomorphic, the tepals 12-15 mm long, caudate, strongly keeled along the abaxial midrib so that the buds appear square in cross-section, glabrous on the abaxial surface, deep yellow. Anthers lacking appendages, held close to one another and to the gynoecium at their bases but recurved at the tips, deep yellow; loculi 5.5-7.5 mm long. Gynoecium straight, 9-13 mm long; ovary glabrous; ovule 1. Drupes dull green; pyrene broad-obovoid, 8-9.5 mm long, 5.5-6mm wide. Seed 1; cotyledons not known." Flowers from January to March with possible sporadic flowering in other months. Occurs on the Newnes Plateau in dry sclerophyll forests and woodlands dominated by a variety of eucalypts, including Eucalyptus sieberi, E. radiata, E. dives, E pauciflora, E. oreades and E. gullickii, on sandstone soils.
3. Persoonia hindii is restricted to the Newnes Plateau, north of Lithgow, New South Wales, where it is known from only 9 locations within Newnes State Forest. Each location occupies only a small geographic area (ie
4. Persoonia hindii is threatened by activities associated with forest management, and sand mining and frequent fire. Persoonia hindii is also at risk due to its extremely low population size.
5. In view of 3 and 4 above the Scientific Committee is of the opinion that Persoonia hindii P.H. Weston & L.A.S. Johnson is likely to become extinct in nature in New South Wales unless the circumstances and factors threatening its survival or evolutionary development cease to operate.
