Dryandra Ser. Niveae - According To George

According To George

With the passage of time following the publication of Bentham's arrangement, D. ser. Niveae was gradually abandoned. As the flowers and fruit are highly similar across all species in the series, it is difficult to distinguish individual species. For this reason the name Dryandra nivea began to be used in a broad sense, to refer to the entire group, and the other species names fell into disuse.

When Alex George published his revision of Dryandra in 1996, he recognised that there were several taxa in the series, and that these could be distinguished by their leaf shape. He resurrected a number of abandoned names, and published some new species and varieties. A new circumscription was given for the series: essentially the series was defined as containing those species in which the flowers of a flower head form a circle about a central hole.

George's placement and circumscription of D. ser. Niveae, as amended in 1999 and 2005, may be summarised as follows:
