General Description:

Macrozamias are part of a very ancient group of plants known as cycads. The genus Macrozamia is endemic to Australia and there are about 25 species. They do not produce flowers and reproduce by means of cones borne on separate male and female plants. All species have dark green, palm-like fronds arising from a central trunk. In some species the trunk is very short or subterranean.

Macrozamia fawcettii is a small cycad with several leaves arising from an underground trunk. The leaves are 500 – 1500 mm long with glossy green, linear-shaped leaflets 50 – 300 mm long. Cones appear irregularly, perhaps at intervals of 3 to 5 years. The male cones are green, cylindrical in shape (150-250 mm long by 50-60 mm wide, aging to a greyish-brown colour. Female cones are also green, cylindrical or barrel shaped to about 300 mm x 150 mm. When ripe, the cone on the female plant breaks apart to release the large, bright red seeds which are about 30mm long by 20mm wide.

As with all cycads, the seeds of M.fawcettii contain compounds which are highly toxic. Seeds of some species have caused fatalities to both humans and livestock. Despite this, Aborigines developed a method of vigorous leaching to remove the toxins and most species of Macrozamia were an important part of their diet.

M.fawcettii has received only limited cultivation but would form a very attractive plant for a garden or container. As with most cycads, the plant is very slow growing and may take 5 years or more to be noticed as a feature plant and many more years to reach anything like a reasonable size. Cones should not be expected for 10 years or more. M.fawcettii is not demanding in its requirements but is best grown in a protected position in moist, well drained soils.

Propagation is from seed which germinates easily without the need for any pretreatment.

Search Tips

By default the search engine tries to locate pages which have exact matches for all of the words entered in your search query. If that fails, it then tries to locate pages which contain any words in your search query. If that happens a short message is displayed at the top of the search results indicating this has been done. In addition, there are several ways to modify the default search behavior.  Note, searches are case insensitive.

Phrase Search
The search engine supports three types of phrase search.

  • To match an exact phrase, use quotes around the phrase. Example: "banksia integrifolia"
  • To match a near (within a couple of words) phrase, use square brackets [around the words]. Example: [banksia integrifolia]
  • To match a far (within several words) phrase, use braces { around the words }. Example: {banksia integrifolia}

+ and - qualifiers
If you prepend a word with + that word is required to be on the page. If you prepend a word with - that word is required to not be on the page. Example: +always -never

* Wildcard
If a query word ends with a * all words on a page which start the same way as that query word will match. Example: gift*

? Wildcard
If a query word contains a ? any character will match that position. Example: b?g

Boolean Search
You can use the following boolean operators in your search: AND, OR, NOT. These operators MUST be in capital letters. Example: (contact AND us) OR (about AND us)

All of these techniques can be combined: +alway* -ne??r*
