Hakea lasianthoides       0

It is a small tree or upright spreading shrub, 1-5m tall, non-lignotuberous. The branchlets and young leaves are appressed-sericeous, ferruginous.

The leaves are flat, linear to narrowly elliptic or obovate, 3-11.5cm long, 3-11mm wide, attenuate, entire, acute.

The inflorescence is with 2-8 flowers. The involucre is 4-5mm long. The pedicels are 5.5-10mm long, woolly-tomentose, with hairs cream, extending onto perianth. The perianth is 4.5-7mm long. The pistil is 7.5-8mm long. The pollen presenter is 1.1-1.4mm long. The gland is 0.2mm high.

The fruit is leaf-like, obliquely transversely elliptic, 2.5-3.1cm long 0.7-0.9 cm wide, smooth, not beaked. The seed is obliquely narrowly elliptic or obovate, 14.5-20mm long. The wing is partly down on only one side of the seed body or apical only.

It is very closely related to Hakea lasiantha. There are some specimens from Bullsbrook and Collie area which erode the differences between these species, particularly by having ferruginous hairs on the pedicel and perianth.

The Genus: Hakea Section: Hakea Serie: Trifurcata having the following characters: Shrubs, rarely small trees, without deeply fissured bark. Leaves compound-terete, rarely mixed with simple-terete (H. trifurcata), or flat, non-petiolate but compound leaves with an undivided basal region, not stem-clasping, entire, not grooved below; venation obscure. Inflorescence an axillary umbel, not resprouting from old rachises in subsequent years, developing within involucre; bracts not persisting at base of inflorescence; rachis obscure. Flowers 1–10; pedicels pubescent. Perianth curved in bud, splitting to base into 4 distinct tepals, pubescent. Pistil 6–10 mm long; pollen presenter a lateral disc; gland a curved flap. Fruit solitary, erect to laterally inserted on stalk, not retained on plant, not markedly woody, smooth, sometimes beaked, not horned, dehiscing fully down both sides. Seed occupying whole valve; wing apical or extending partly down one side of seed body only.

A group of five species all occurring in W.A.

It should tolerate light pruning. It is useful for screening and as a light windbreak.

Cuttings instructions
Take the cuttings in early fall. Soak them in a hormonal preparation for cuttings before planting them in a substrate composed of 50% perlite and 50% heather earth. Keep them sufficiently moist at a temperature of 20°C in sealed freezer bags. Keep the light on for 16 hours a day.
