First collection: "Near St John' s Lake, Auckland", H. Carse 481/8, 28.1.1925 (CHR 291478).
The very scattered distribution indicates that this sp. is introduced although it was first published as indigenous to N.Z. (Type:CHR 145441, Lincoln, opposite school, in damp hollow near golf course, E. Edgar, 13.1.1964) but at that time it was not realised that J. amabilis matched some undescribed Australian plants.
