"Banksia armata" var. "ignicida" is a variety of shrub endemic to Western Australia.

Description

"B. armata" var. "ignicida" grows as an upright shrub, up to three metres in height, with deeply serrated leaves and yellow or sometimes pink inflorescences. Unlike "B. armata" var. "armata", it lacks a lignotuber.

Distribution and habitat

It occurs through much of the south-west, being widespread between Pingelly and Katanning, and also between Esperance and Israelite Bay. It grows amongst tall scrub on a range of sandy and rocky soils.

Taxonomy

Specimens of "B. armata" were first collected in 1801, and the species was published in 1810 as "Dryandra armata". In 1996, Alex George published "D. armata" var. "ignicida" based on a type specimen collected by him east of Woodanilling. The varietal epithet is from the Latin "ignis" ("fire") and "-cidus" ("killing"), in reference to the fact that this variety is killed by fire (because it lacks a lignotuber). In 2007, all "Dryandra" species were transferred to "Banksia" by Austin Mast and Kevin Thiele; hence the current name of this variety is "Banksia armata" var. "ignicida" (A.S.George) A.R.Mast & K.R.Thiele.
