Hakea cygna subsp. needlei Lamont in B.Lamont et al., J. Linn. Soc., Bot. 94: 440 (1987).

T: 23 km S of Lake King, then 5 km W, W.A., 29 Sept. 1972, B.Lamont s.n.; holo: PERTH.


Erect shrub, 0.4–2 m tall, non-sprouting. Branchlets densely sericeous at flowering. Leaves terete or trigonous, narrowly linear, 2–7.5 cm long, 1.2–2 mm wide, glabrous; marginal veins prominent; longitudinal veins 1–3, obscure above, faintly visible below.

Inflorescences a solitary axillary umbelliform raceme, with 6–14 flowers; pedicels cream white, glabrous, rarely appressed-pubescent. Perianth cream-white. Pistil 5.5–7 mm long; gland a small flap, c. 0.5 mm high.

Fruit shortly stalked, with supporting branch usually markedly thickened, obliquely ovate-elliptic, 2.1–3.7 cm long, 1.2–2 cm wide, scarcely beaked but ±prominently apiculate. Seed obliquely broadly ovate (almost triangular) to obliquely circular, 12–20 mm long; wing encircling the ±centred body, pale brown with blackish brown radiating streaks.

Distribution and ecology

Restricted to a small area with populations spread over c. 10 km just south of Lake King, W.A.

Flowering time

Flowers August to September.

Derivation of name

The epithet needlei is a reference to the shape of the leaves of this subspecies.


How the infraspecific taxa differ

Ssp. needlei differs from ssp. cygna only in its narrow needle-like leaves and its confinement to a small area south of Lake King.


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, H. subsulcata and H. ulicina, mostly from southern WA but also from south-eastern Australia.  

Conservation status

In Western Australia denoted as Priority One - Poorly Known: taxa which are known from one or a few (generally <5) populations which are under threat, either due to small population size, or being on lands under immediate threat, e.g. road verges, urban areas, farmland, active mineral leases, etc., or the plants are under threat, e.g. from disease, grazing by feral animals, etc. May include taxa with threatened populations on protected lands. Such taxa are under consideration for declaration as ‘rare flora’, but are in urgent need of further survey.
