Hakea ulicina var. latifolia J.M.Black, Trans. & Proc. Roy. Soc. S. Australia 54: 59 (1930). T: Ninety Mile Desert, near the Coorong, S.A., E.Ashby s.n.; holo: AD98132246.
Erect shrub, 1.2–4 m tall, resprouting from lignotuber and often suckering from horizontal roots. Branchlets densely tomentose to glabrescent at flowering. Leaves narrowly obovate to linear, flat, twisted through 90° at base, 4–14 cm long, 3–12 mm wide, glabrous; marginal veins prominent; longitudinal veins prominent, with 3–5 (rarely 7) above and below; secondary venation obscure.
Inflorescence a solitary axillary umbelliform raceme, with 10–36 flowers; pedicels cream-white, glabrous or rarely ±sparsely appressed-pubescent. Perianth cream-white. Pistil 4–5.7 mm long; gland a small flap, 0.3–0.4 mm high.
Fruit subsessile, ±obliquely ovate, slightly curved towards apex, 1.5–2.6 cm long, 0.8–1.3 cm wide, scarcely beaked but shortly apiculate. Seed obliquely narrowly ovate-elliptic, 10–16 mm long; wing extending partly or fully down both sides of body, more broadly on adaxial side, blackish brown.
Distribution and ecology
Occurs from south-eastern S.A. to the Grampians and western mallee regions of Vic. and east to the Otway Ra. with an apparent outlier 250 km to the east, near Sale in South Gippsland. Found in sclerophyll forest and, frequently in scattered populations, in mallee-heath, in acidic sandy soil.

Derivation of name
From repullulans, Latin for sprouting again, a reference to the lignotuberous resprouting and the suckering of this species.
Part of the Conogynoides group recognised by Bentham and characterised by a conical pollen presenter, veined leaves, glabrous perianth and fruits without horns. Barker et al. (1999) recognised a number of informal morphological groups within the section.
One of these was the Ulicina group. This group of 21 Hakea species was combined morphologically because they all have simple flat leaves or leaves which are apparently terete but when looked at in cross section are clearly angled; these angled leaves are longitudinally furrowed and often referred to as sulcate. Furthermore the group has inflorescences with 6-80 small flowers (with 3-18 mm long pistils) and erect woody fruits.
Members of the group are H. aenigma, H. carinata, H. costata, H. cygna, H. dohertyi, H. erecta, H. gilbertii, H. invaginata, H. lehmanniana, H. marginata, H. meisneriana, H. mitchellii, H. myrtoides, H. pycnoneura, H. repullulans, H. rigida, H. scoparia, H. stenocarpa, H. sulcata, subsulcata and H. ulicina, mostly from southern WA but also from south-eastern Australia.
Hakea repullulans is close to and was previously confused with H. ulicina . The latter differs principally in being non-sprouting but also in the usually much narrower leaves (1.5–4 mm wide) and the usually fewer flowers in the inflorescence (6–18).
Further discussion of morphological and anatomical differences between H. ulicina and H. repullulans, including variation in adult and juvenile foliage can be found in Helen Lee (1984).

The Molyneux specimen from South Gippsland, cited in the representative specimens (Molyneux s.n.) is a significant disjunct occurrence for H. repullalans, but its identity does not seem in doubt as the plants are recorded as resprouters (root-suckering) and there are 24–26 flowers per inflorescence (compare with H. ulicina in this region, a nonsprouter, with only 6–18 flowers per inflorescence).
