Australian Plant Census:
* ''Grevillea patentiloba''
F.Muell. subsp. ''patentiloba''
is a prostrate to low, spreading shrub usually less than high that flowers from June to November.
* ''Grevillea patentiloba'' subsp. ''platypoda''
(F.Muell.) Olde & Marriott is a robust, more or less upright shrub usually high that flowers from July to November.
