NSW Scientific Committee - final determination
The Scientific Committee has found that:
1. Pomaderris adnata N.G. Walsh & F. Coates was first described in 1997 (Walsh, N.G. and Coates, F., 1997, New taxa, new combinations and an infrageneric classification in Pomaderris (Rhamnaceae). Muelleria 10: 27-56).
2. The following description is taken from Harden and Murray (2000), Supplement to Flora of NSW Volume 1. Spreading shrub 1-2 m high, new growth pubescent with greyish stellate hairs. Leaves narrow-elliptic to elliptic, or oblanceolate, 1.5-3 cm long, 3-8 mm wide, margins recurved and entire to more or less sinuate; upper surface glabrous; lower surface pubescent with greyish stellate hairs, secondary veins apparent with sparse, appressed greyish or yellow to rusty simple hairs and greyish stellate hairs. Flowers pale yellow, in short axillary cymes forming narrow terminal or axillary panicles. Sepals not persistent in fruit. Petals usually present on most flowers. Capsule and ovary stellate hairy, capsule immersed for about half of its length in the tomentose hypanthium. Grows in heathy woodland and dry sclerophyll forest.
3. Pomaderris adnata may be distinguished from other similar Pomaderris species in the area by having petals, by the absence of simple hairs on the stems and by the short, sparse and appressed hairs on the midrib and larger lateral veins on the underside of the leaf surface.
4. The species is only known from one population of less than ten plants on the Illawarra escarpment, north of Wollongong. At this site P. adnata occurs in Eucalyptus sieberi / Corymbia gummifera forest with occasional Hakea salicifolia and an understorey of Acacia suaveolens, Hakea dactyloides, Lambertia formosa, Leptospermum trinervium, Banksia spinulosa var. spinulosa, Leucopogon lanceolatus, Lomatia silaifolia. Herbs include Lomandra longifolia, L. obliqua, L. sp., Entolasia stricta, Billardiera scandens, Smilax glyciphylla, Dianella sp, and Patersonia sp.
5. Despite searches in the area, no other locations have been found.
6. Possible threats include dumping, road verge maintenance activities, and weed invasion. Due to the small population size and very limited extent the species is susceptible to catastrophic events.
7. In view of 3, 4, 5 & 6 above the Scientific Committee is of the opinion that the species 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.
