Banksia trifontinalis, commonly known as Three Springs Dryandra, is a shrub endemic to Western Australia.

Description

It grows as an openly branched shrub, and can reach up to two metres high. It has long, narrow, serrated leaves, and a yellow inflorescence.

Taxonomy

The type specimen was collected west of Three Springs, Western Australia by Alex George on 6 August 1986. George published a description of the species in 1996, naming it Dryandra trifontinalis. The specific epithet is from the Latin tri- ("three") and fontinalis ("of a spring"), in reference to the town of Three Springs.[1][2]

In 2007, all Dryandra species were transferred to Banksia by Austin Mast and Kevin Thiele. Hence the current full name of the species is Banksia trifontinalis (A.S.George) A.R.Mast & K.R.Thiele.[3]

Distribution
