Grevillea epicroca Stajsic & Molyneux, Fl. Australia 17A: 502 (2000)

T: Merricumbene Fire Trail, 18.4 km S of Batemans Bay road, c. 19 km SW of Braidwood, N.S.W., 30 Mar. 1976, M.D.Crisp 2008 ; holo: CANB; iso: NSW.

Grevillea victoriae 'Unassigned 5', of D.J.McGillivray & R.O.Makinson, Grevillea 322 (1995). 

Regenerates probably from seed only.

Shrub 1–2.5 m tall. Branchlets subsericeous to almost glabrous, softly angular in cross-section. Leaves elliptic to narrowly so or lanceolate, (3.5–) 4–7 cm long, 8–12 (–20) mm wide, upper surface smooth, ?dull, with the lateral veins evident; margins shortly recurved; lower surface with an open to sparse indumentum of appressed hairs (ground tissue easily visible between hairs). Conflorescence terminal or subterminal-axillary, pedunculate, decurved to pendulous, simple or basally few-branched; unit conflorescence ovoid or a loose sometimes subsecund cluster, few- to many-flowered; floral rachis 10–25 mm long. Flower colour: perianth red with reddish hairs; style red or reddish pink. Perianth densely subsericeous outside (biramous hairs, with a few scattered very inconspicuous erect glandular hairs intermixed), bearded inside. Pistil 16–20 mm long; style with minute hairs towards apex; pollen-presenter lateral. Follicle 18–24 mm long, with faint longitudinal ridges. 

Occurs in south-eastern N.S.W., known only from a small area of the tablelands escarpment country W of Moruya (upper Deua R. and Bendethera Mtn area). Grows at 700–1000 m alt. in tall moist Eucalyptus forest, on steep rocky slopes on substrates variously reported as sandstone, quartzite, phyllite, or volcanic. Flowers Nov.–May. Map 235.

N.S.W.: 1 km NE along boundary fire trail from junction of River Forest Rd and Gollaribee Fire Trail, 14 km S of Monga, P.Ollerenshaw 1806 (CANB, MEL, NSW); Deua Natl Park, knoll c. 1.3 km directly N of Bendethera Mtn, N.Taws 329 (CANB, NSW); downstream on Deua R., 400 m from 'Alpine' property above junction of Deua R. and Curmullee Ck, T.Whaite 3008 & J.Whaite (NSW).

Grevillea epicroca has new vegetative growth green or briefly pink, and with a leaf length/width ratio of (3:1–) 4:1 to 6:1 or more, floral rachises apparently with mixed tan and rusty brown hairs, the limb of the bud obtuse but distinctly square in face view, and the pollen-presenter ventrally very concave in cross-section. The open appressed indumentum of the leaf lower surface is distinctive relative to G. victoriae , G. oxyantha , G. brevifolia and most populations of G. parvula (for exceptions, see notes under that species). Taxa with a similar lower leaf surface indumentum include G. monslacana , which differs in having thicker, more leathery leaves that are proportionately a little wider, the bud limb subglobose and obtuse and rounded in face view, and a pollen-presenter that is ventrally convex in cross-section. Grevillea rhyolitica may have an open indumentum on the leaf lower surface, but either (subsp. rhyolitica ) has the hairs spreading, or (subsp. semivestita ) appressed but very short and almost rhombic in shape, and in either case has the outer perianth surface tomentose (±spreading hairs).

A population in the Big Badja to Minuma Ra. area of the N.S.W. tablelands escarpment is here unassigned to species. It has some points of similarity to both G. epicroca and G. parvula and to 'G. aff victoriae (Bemboka)'; see also note under G. parvula.
