holathera is a widely distributed species that varies from a weak perennial
or annual arid form (to which the name A. muelleri has been applied) to
a stronger wet-area tropical perennial with its broad leaved form var.
latifolia. It intergrades almost imperceptably into A. contorta at the
arid end of its range, differing only in its longer lemma which is purplish at
maturity. The name A. holathera used to apply only to a form in which
the lemma column was descibed as having a weak articulation and the awns were
reported as being shorter, with the name A. browniana being used for the
more commonly occurring form with a distinct lemma articulation and longer
awns, but these differences were shown not to hold up on close inspection
Widespread over most
of arid Australia and extending into the Philippines.
