Short Notes
Gymnosperm, status designated by author
Macrozamia lomandroides is a cycad with an underground stem up to 25cm in diameter. It has an crown of 2-6 erect to spreading leaves. The dull green, mature leaves are 30-80cm long and hairless, except for wool at the base. Each leaf consists of 50-90 leaflets arranged on a strongly spirally twisted (1-8 times) rhachis (central stalk). The rhachis has two pale green to cream marginal bands especially noticeable towards the end of the leaf. The dark green leaflets are thick, leathery, dull, broadly linear, have 2-8 small teeth near the tip (1-6 teeth on one side and 1 or 2 teeth on the other) and are 20-35cm long by 0.9-1.4cm wide. The leaflet bases are pale green to cream and slightly thickened.
Male and female cones develop on separate plants and are somewhat pineapple-like in appearance. Male cones are cylindrical, 12-15cm long and 4-5cm in diameter. Female cones are ovoid, 12-18cm long and 7-9cm in diameter. Seeds are oblong, 2.2-2.6cm long, 1.8-2.2cm in diameter and orange to red when ripe.
Macrozamia lomandroides is distinguished from other Macrozamia species by the small sharp teeth at the apex of the leaflets. (Jones 1991; Forster et al. 1994; Halford 1995; Hill 1998)

Macrozamia lomandroides occurs in Banksia and eucalypt dominated woodland or open forest communities with dense low shrubby (wallum) or grassy understorey. The areas are usually flat or rarely on a slope up to 40m above sea level. The plants growing among rocks on grey silty loam or sandy soils. (Halford 1995)
Adult Macrozamia plants have an underground stem and are able to resprout after loss of the above-ground foliage from fire. Seedlings and unburied seeds are usually killed by fire. Synchronous cone formation often follows fire. (Halford 1995; Queensland Herbarium 2007)
Mature cones have been recorded in October and November. Cones may not be annual when conditions are unfavourable. Ripe seeds occur from March to April and are not ready to germinate for at least nine months due to the delayed fertilisation unique among cycads. There is little evidence of seed dispersal in this species, the seedlings often being clumped in close proximity to the parent plant. A species of Tranes weevil plays a role in the pollination of Macrozamia lomandroides. (Halford 1995; Queensland Herbarium 2007)
All Macrozamia species contain toxins which can cause debilitating symptoms or death if ingested in sufficient quantities. (Halford 1995; Queensland Herbarium 2007)
