Editing Macrozamia spiralis (section)

===Habitat Conditions: ===
''M. spiralis''
grows near Richmond, to the west of Sydney, in areas of flat, poor quality, sometimes sandy, soil.
''M. spiralis''
normally grows under a eucalypt canopy in a pattern of scattered individual plants or, occasionally, small clusters or large groups of plants. These small clusters of plants contain as many as 10-12 plants growing within a 2 metre radius, while the largest group of plants that we have seen contained approximately 40 plants growing in an area measuring 2.5 x 5 metres.
The reason for this clumping tendency is somewhat intriguing, though we suspect that it is simply the result of seeds germinating and growing to maturity in close proximity to parent plants, while the reason for the scattered individual plants is partly attributable to seed dispersal by marsupial animals.
In very rare cases a plant will be found with multiple heads, no doubt due to damage to the upper part of the caudex. One such plant which we have seen had seven separate heads of fronds, giving the effect of a very leafy specimen (albeit with reduced sized fronds).
