Bentham's Arrangement
As Bentham never visited Australia, he only had access to preserved specimens. Thus he was unable to distinguish between some similar pairs of species, and so reduced the number of species to 46. He retained Isostylis, but replaced Meissner's four series by four sections based on leaf, style and pollen-presenter characters. Two of these, Oncostylis and Eubanksia, were reasonably well-defined and homogeneous; section Orthostylis was somewhat heterogeneous; section Cyrtostylis was erected to contain the species that did not belong in the other sections, and was therefore highly heterogeneous.
George Bentham's 1870 taxonomic arrangement of Banksia may be summarised as follows:
- Banksia
- B. sect. Oncostylis
- B. pulchella
- B. Meissneri
- B. nutans
- B. sphærocarpa
- B. sphaerocarpa var. glabrescens (now B. incana)
- B. sphaerocarpa var. latifolia (now B. sphaerocarpa var. sphaerocarpa)
- B. tricuspis
- B. occidentalis
- B. littoralis
- B. ericifolia
- B. spinulosa
- B. collina (now B. spinulosa var. collina)
- B. verticillata
- B. dryandroides
- B. Brownii
- B. sect. Cyrtostylis
- B. attenuata
- B. media
- B. Solandri
- B. Goodii
- B. petiolaris
- B. repens
- B. prostrata (now B. gardneri)
- B. grandis
- B. quercifolia
- B. quercifolia var. integrifolia (now B. oreophila)
- B. Baueri
- B. sect. Eubanksia

Famous quotes containing the words bentham and/or arrangement:
“The principle of asceticism never was, nor ever can be, consistently pursued by any living creature. Let but one tenth part of the inhabitants of the earth pursue it consistently, and in a day’s time they will have turned it into a Hell.”
—Jeremy Bentham (1748–1832)
“There is no reason why parents who work hard at a job to support a family, who nurture children during the hours at home, and who have searched for and selected the best [daycare] arrangement possible for their children need to feel anxious and guilty. It almost seems as if our culture wants parents to experience these negative feelings.”
—Gwen Morgan (20th century)
