Adenanthos detmoldii

Adenanthos detmoldii, commonly known as Scott River Jugflower or Yellow Jugflower, is a species of shrub in the family Proteaceae. It is endemic to the south-west of Western Australia.

It grows as an erect shrub to 4 m (13 ft) in height, with hairy branches and long, narrow leaves up to 80 mm length and about 5 mm wide.

The flowers, which appear between August and November, consist of a tubular perianth about 25 mm long, and a style about 40 mm long. The perianth is yellow with an orange throat that becomes brown following pollination.

The type specimen of A. detmoldii was collected from the vicinity of the Blackwood River around 1870, and sent to Ferdinand von Mueller who published the species in Volume 8 of his Fragmenta Phytographiae Australiae in 1874.

The original type specimen cites "Blackwood-River; J. Forrest", and this has sometimes been interpreted as referring to John Forrest, but John Forrest's brother James is known to have "achieved some repute by making botanical collections of the flora of the Blackwood district for Baron von Mueller", and an isotype lodged at the Botanical Garden in Berlin has been labelled by Ludwig Diels "Blackwood River leg. Jas. Forrest".

A. detmoldii is restricted to the vicinity of the Scott and Blackwood Rivers east of Augusta, Western Australia.

Unusually for Adenanthos species, it favours damp winter-wet, sandy flats, where it co-occurs with Banksia ser. Dryandra species, Grevillea species, grasses and sedges. It is often the most abundant shrub where it occurs.
