Xerochrysum bracteatum subsp. (North Stradbroke Island L.Durrington 675), A. E. Holland in P.D. Bostock and A.E. Holland (eds), Census Queensl. Fl. 32 (2007).

Erect, perennial, tap-rooted herb. Cauline leaves obovate, margin cobwebby, hispid and scabrid, apex obtuse and mucronate. Abaxial indumentum with glands, midvein indumentum hispid with scattered glands; adaxial indumentum hispid and scabrid. Medial phyllaries ovate to narrow ovate, abaxially yellow.

Habitat and distribution

Collections from coastal sand dunes and dune swales on Minjerribah (North Stradbroke Island), K’gari (Fraser Island) and Mulgumpin ( Moreton Island ), and from coastal headlands from the Whitsunday Islands south to Diamond Head, in the Central Mackay Coast, South Eastern Queensland and New South Wales North Coast bioregions are tentatively assigned to this entity.

Notes

Seedling leaves seen on Mulgumpin (Moreton Island) can be up to 35 cm long and 8 cm wide, the largest in the genus. Xerochrysum sp. North Stradbroke Island may be conspecific with H. macrocephalum but molecular and morphological data were inconclusive. Further research is underway at the University of New England.
