Editing Macrozamia heteromera (section)

===History: ===
''M. heteromera'' was named
by C. Moore in 1884 after its divided pinnae (which were observed to be "different"
and "variable"). In 1998, the ''M. heteromera'' complex was the
subject of a major revision by David Jones, which resulted in two new species
with divided pinnae, ''M. glaucophylla'' and ''M. polymorphya'', being segregated
from ''M. heteromera'', after being identified by Jones as separate and distinct species.
Prior to the 1998 revision of this species, cycad enthusiasts referred to
two "forms" of ''M. heteromera'' " the "blue form" and the "green form."
In retrospect, the "blue form" covered the species we now know as ''M. glaucophylla'';
while the "green form" covered:

<ol><li> the species we now know to be (true) ''M. heteromera'',
</li><li> the species we now know as ''M. polymorpha'', and
</li><li> the relatively large population of hybrid plants that are evident, in and around the southern parts of the Pilliga, in areas where ''M. diplomera'' and ''M. polymorpha'' grow in close proximity to each other.
