It is found only in the North Island of New Zealand. Its conservation status (2018) is "At Risk (relict)" under the New Zealand Threat Classification System.

Description

Carmichaelia williamsii is the only yellow-flowered native broom, and it is distinguished from the introduced broom (Cytisus scoparius (L.) Link) by its light green, much wider, and more flattened branches, together with its larger, pale-yellow flowers which have purple or red veins, and its late-winter flowering (July to October, though flowering can occur throughout the year).

Taxonomy

The species was first described by Thomas Kirk in 1880. The earliest record in AVH, [https://avh.ala.org.au/occurrences/92b6cdba-13a3-4eee-a9e7-50aedb073714 SP026354] was collected by Bishop William Williams in 1879 somewhere in the North Island,{{Cite web|url=https://avh.ala.org.au/occurrences/92b6cdba-13a3-4eee-a9e7-50aedb073714 |title= SP026354, Australasian Virtual Herbarium, Council of Heads of Australasian Herbaria|website=avh.ala.org.au|language=en-AU|access-date=2019-12-08}} and for whom Kirk named it.
