Raoulia grandiflora, or the large-flowered mat daisy,[1] is a species of flowering plant from the South Island of New Zealand.

Lvs densely imbricate, 5-10 × 1-2 mm., 3-nerved, ovate-lanceolate-spathulate, tapering to subacute tip, clad in upper part on both surfaces in appressed silvery tomentum, loosely tomentose near base.

linear, contracted near middle, obtuse, with conspicuous white radiate tips up to c. 5 mm.

[5] This species often appears in scree fields where tussock mats leave openings.

In small hollows that accumulate water with a sandy substrate, it can be found in colluvium with Epilobium pernitens, Carpha alpina, Oreomyrrhis colensoi, and Viola cunninghamii.

[5] In gravel fields it is know to associate with Veronica pulvinaris, Anisotome imbricata, and Dracophyllum pronum.
