Persoonia myrtilloides Sieber ex Schult. & Schult.f., Mant. 3: 272 (1827)

Linkia myrtilloides (Sieber ex Schult. & Schult.f.) Kuntze, Revis. Gen. Pl. 2: 579 (1891). T: locality unknown, N.S.W., 1823, F.W.Sieber 52 ; lecto: M; isolecto: FI, K, L, M, MEL, NSW, NY, fide P.H.Weston & L.A.S.Johnson, Telopea 4: 273 (1991).

Erect to spreading shrubs 0.5–2.5 m tall. Bark smooth. Hairs greyish, appressed to patent. Young branchlets moderately hairy. Leaves narrowly to broadly elliptic to ovate, 1.2–5 cm long, 4–30 mm wide, flat, with slightly recurved margins, sometimes slightly incurved, spreading, straight, innocuous, concolorous to strongly discolorous, not glaucous, sparsely to moderately hairy when immature, glabrescent, smooth to moderately scabrous. Inflorescence auxotelic, 1–40-flowered; rachis 0–17 cm long. Flowers subtended by scale leaves and leaves; pedicels 2–10 mm long, spreading to recurved, sparsely to moderately hairy; tepals 9–12 mm long, prominently caudate with dorsal tails, sparsely to moderately hairy on outside. Ovary glabrous; ovules 2. 

Occurs from the upper Goulburn River through the Wollemi district to Wentworth Falls, N.S.W., in the upper Blue Mountains, eastern N.S.W. Flowers Dec.–Apr. 

Persoonia myrtilloides often occurs sympatrically, and occasionally hybridises, with P. recedens , P. acerosa and P. levis . It also sometimes grows with P. chamaepitys , P. linearis and P. laurina .

Morphological variation in P. myrtilloides is geographically correlated, ranging from populations with small, broadly elliptic leaves and with long, reflexed tepal tips in the north to those with larger, narrowly elliptic leaves and with shorter, slightly recurved tepal tips in the south. Geographical variation in leaf morphology seems to be clinal, but with regard to the morphology of tepal tips it seems to involve an abrupt transition in the Capertee area. Two subspecies are recognised.
