 This clade became the basis of B. subseries <unk> , which Thiele defined as containing those taxa with very long and slender styles , smoothly convex perianth limbs without a <unk> ridge , and thickened margins . In accordance with their cladogram , their arrangement placed B. violacea first in taxonomic sequence , followed by B. laricina ( Rose @-@ <unk> Banksia ) . However , Thiele and Ladiges ' arrangement was not accepted by George , who , questioning the emphasis on <unk> , rejected most of their changes in his 1999 arrangement , restored B. series Abietinae to his broader 1981 definition , and abandoned all of Thiele and Ladiges ' subseries . George commented that the species has no close relatives , being " loosely allied " to B. sphaerocarpa ( Fox Banksia ) and B. <unk> ( Swamp Fox Banksia ) . Despite this , the sequence of the series was altered so that B. violacea fell between B. <unk> ( Burma Road Banksia ) and B. incana , and its placement in George 's arrangement may be summarised as follows :
