Grevillea manglesii (Graham) Planch., Hort. Donat. 96 (1858)

Anadenia manglesii Graham, Edinburgh New Philos. J. 27(53): 189 (1839); Grevillea manglesii (Graham) McGill., in D.J.McGillivray & R.O.Makinson, Grevillea 427 (1993), comb. superfl . T: 'Anadenia manglesii 25 July 1839. Under this name I have somewhere published it ...' [cultivated from Clapton Nursery; R.Graham script; protologue]; neo: E, fide D.J.McGillivray & R.O.Makinson, Grevillea 427 (1993).

Shrub 1.5–3 (–5) m high. Branchlets glabrous, sometimes glaucous. Leaves 2–8 cm long, 10–50 mm wide, trifid to tripartite with ascending to spreading primary lobes and often with shallow secondary division (subsp. manglesii ), or basally long-cuneate and apically 2- or 3-lobed (subsp. ornithopoda ), or biternate with spreading primary lobes and deep secondary division (subsp. dissectifolia ); ultimate lobes triangular or sometimes rounded; apices scarcely to moderately pungent; margins flat to recurved; lower surface exposed, glabrous. Unit conflorescence acropetal, shortly subconical to subglobose or shortly cylindrical; floral rachis glabrous. Perianth glabrous outside. Pistil 3.3–5.5 mm long; stylar swelling ovoid; pollen-presenter conical with base broader than apex of style. Follicle obloid-ovoid to slightly obovoid, 7–10.5 mm long, rugose-tuberculate. 

Occurs in south-western W.A. 

Note: many loan specimens were determined by McGillivray between c. 1976 and 1986 as subspecies within G. glabrata (Lindl.) Meisn., a name since superseded by G. manglesii (Graham) Planch. The correspondence of these subspecific taxa with the subspecies here recognised is exact.

There are three subspecies.

(R.O.Makinson)

1 Most leaves 4–8 cm long, basally narrowly long-cuneate and apically trifid or bifid, with primary division only

subsp. ornithopoda

1: Most leaves 2–5 cm long, basally cuneate to broadly so to almost truncate, 3–7-fid or -partite; primary leaf lobes often divided

2

2 Leaves with primary lobes coarsely dentate or shallowly 3-fid; ultimate teeth or lobes triangular to broadly triangular, 2–8 mm wide

subsp. manglesii

2: Leaves with primary lobes deeply 3-partite (sinuses extending almost to midvein of primary lobe); ultimate leaf lobes sublinear to narrowly triangular, c. 1.5–2.5 mm wide

subsp. dissectifolia
