Editorial Note

Olearia arborescens has been transferred to Shawia, rendering this naturally occurring cross an intergeneric hybrid.

The nothogenus Shawia × Olearia has not yet been named. We treat this hybrid under its name in Olearia, pending further developments, and a full revision of Olearia sensu lato.

Intermediate between the parents; leaves resembling those of O. lacunosa but comparatively shorter and broader, elliptic, with whitish tomentum beneath, up to 4 in. long and 1 in. wide. Davies, New Zealand Native Plant Studies, t. 125. A natural hybrid.
