T: inter Cape Arid et Lucky Bay, Western Australia, [1824], W.Baxter s.n.; ?holo: BM.

Hakea roei Benth., Fl. Austral. 5: 499 (1870). T: int. S.W. Australia, without date, J.S.Roe s.n.; ?holo: K.


Small tree or shrub, rounded or erect, 1–4 m high, non-lignotuberous. Branchlets and young leaves appressed-pubescent, ferruginous. Leaves simple, narrowly elliptic or obovate, 3–12 cm long, 0.3–1.6 cm wide, attenuate, entire, rounded, rarely truncate.

Inflorescence a raceme with 4–14 flowers; rachis 3–10 mm long, tomentose; pedicels 5–7.5 mm long, densely appressed-pubescent with hairs ferruginous and white, extending onto perianth. Perianth 6–11 mm long, cream-white inside. Pistil 13–16 mm long; gland U-shaped.

Fruit obliquely obovate, 4.5–5.5 cm long, 3.7–4.5 cm wide, with corky tetrahedral protuberances of ±uneven size. Seed broadly ovate, elliptic or obovate, 25–36 mm long; wing encircling seed body.

Distribution and ecology

Occurs from Ravensthorpe to Israelite Bay, near the south coast of Western Australia.

Flowering time

Flowers Oct.–Nov.

Derivation of name

From pandanus, a genus of plants and carpa, Greek for fruit, a reference to the pandan-like fruits of this species.


How the infraspecific taxa differ

Subspecies pandanicarpa and subspecies crassifolia can be distinguished by the ornamentation of the fruit surface. Ssp. pandanicarpa has decidedly raised corky tetrahedral projections on the fruit from a young age, as can be seen in the photograph here, while ssp. crassifolia is more or less smooth at a young age, developing a rougher but still comparatively smooth corky layer with age. The pattern on the outer layer of the fruit of ssp. crassifolia resembles that of drying mud in a claypan.

Ssp. pandanicarpa also tends to have a more easterly distribution than ssp. crassifolia. It is found from Ravensthorpe to Isaelite Bay while ssp. crassifolia occurs in the Newdegate-Albany-Ravensthorpe area.


Part of Section Hakea of Bentham (as Euhakea) and characterised by a non-conical pollen presenter, leaves without obvious venation, perianths with or without hairs and fruits with or without horns. Barker et al. (1999) recognised a number of informal morphological groups within the section.

Within this section 6 species were assigned to the informal Ceratophylla group by Barker et al. (1999). The group is close to the Obliqua group, sharing the morphological characteristics of few-flowered inflorescences with pubescent flowers on an obscure rachis, oblique pollen presenters and distinctly woody fruits without horns and usually without beaks and seed in which the wing encircles the seed body or is broadly down one side; the groups differ in the flat leaves of this group compared with the terete leaves of the Obliqua group. 

Members of the group are H. baxteri, H. brownii, H. ceratophylla, H. flabellifolia, H. hookeriana  and H. pandanicarpa, all from south-west WA.

An image on the web at labelled as H. nitida is almost certainly H. pandanicarpa.
