Diagnosis

Pultenaea mutabilis is distinguished from other members of the P. glabra complex by the combination of irregular branching architecture, leaves with little or no ornamentation on the adaxial surface, and indistinct low, granular ornamentation on the abaxial surface, the narrow, linear stipules and papery bracteoles; the inflorescences produced on shoots that continue vegetative growth; flowers produced in the axils of leaves that are identical to those on vegetative shoot sectors; and the internodes separating sequential flowers being the same length as those separating sterile leaves.

Etymology

From the Latin mutabilis , inconsistent, referencing the various morphological expressions of this species that are closely related genetically but that have remarkably disparate fieldpresentation.
