The Banksia integrifolia L.f. species complex (Proteaceae)

Abstract

The Banksia integrifolia (Proteaceae : Grevilleoideae) species complex currently comprises three varieties: var. aquilonia from northern Queensland; var. integrifolia from coastal Victoria and New South Wales; and var. compar, which is polymorphic and comprises two forms, a coastal form from southern Queensland and a montane form from north-eastern New South Wales and south-eastern Queensland. Ordination analysis of morphological characters of adults and seedlings indicates that the montane populations of var. compar comprise a separate taxon, which is phenetically closer to var. integrifolia than it is to typical var. compar. Banksia integrifolia var. aquilonia is phenetically quite distinct from the remaining taxa. The new names and combinations Banksia integrifolia subsp. monticola K.R. Thiele, B. integrifolia subsp. aquilonia (A.S. George) K.R. Thiele and B. integrifolia subsp. compar (R.Br.) K.R. Thiele are published.
