"Banksia sessilis" var. "flabellifolia" is a variety of "Banksia sessilis" (Parrot Bush).

Description

It grows as a shrub up to five metres high. Unlike other varieties of "B. sessilis", it has hairless stems. The leaves are fan shaped, with a long, toothless lower margin, and a toothed end. As such its leaves are quite similar to some of those of "B. sessilis" var. "cygnorum", but are larger, being up to four centimetres long and 3.5 centimetres wide. They also lack lobes at the base. As with other varieties of "B. sessilis", the flowers are greenish-yellow. Each head contains around 90 flowers.cite book | first = Tony | last = Cavanagh | coauthords = Pieroni, Margaret | year = 2006 | title = The Dryandras | publisher = Melbourne: Australian Plants Society (SGAP Victoria); Perth: Wildflower Society of Western Australia | id = ISBN 1-876473-54-1] Flora of Australia Online | name = "Dryandra sessilis" var.

Taxonomy

This variety was first published by Alex George in 1996, based on a specimen he collected on 11 August 1993 on West Binnu Road, 4.4 kilometres east of Yeringa South Road, north-north-west of Northampton, Western Australia. The varietal epithet is from the Latin "flabellum" ("fan") and "folium" ("leaf"), and refers to the fan-shaped leaves characteristic of this variety.cite journal | first = Alex | last = George | year = 1996 | title = New taxa and a new infrageneric classification in "Dryandra" R.Br. (Proteaceae: Grevilleoideae) | journal = Nuytsia | volume = 10 | issue = 3 | pages = 313–408] The name given at the time was "Dryandra sessilis" var. "flabellifolia", and this stood until 2007, when Austin Mast and Kevin Thiele transferred "Dryandra" into "Banksia";cite journal | author = Mast, Austin R. and Kevin Thiele | year = 2007 | title = The transfer of Dryandra R.Br. to Banksia L.f. (Proteaceae) | journal = Australian Systematic Botany | volume = 20 | pages = 63–71 | doi = 10.1071/SB06016] thus the variety's current full name is "Banksia sessilis" var.

In 1999, George placed it between "B. sessilis" var. "sessilis" and "B. sessilis" var. "cordata" in phyletic order.cite book | first = Alex | last = George | year = 1999 | chapter = Dryandra | editor = Wilson, Annette (ed.) | title = Flora of Australia: Volume 17B: Proteaceae 3: Hakea to Dryandra | publisher = CSIRO Publishing / Australian Biological Resources Study | isbn = ISBN 0-643-06454-0]

Distribution and habitat

"B. sessilis" var. "flabellifolia" grows in both deep sand and on laterite, between Geraldton and Kalbarri inland to Northampton and south as far as Moora, in the South West Botanical Province of Western Australia

Cultivation

This variety is little known in cultivation. It is suggested that cultivation requirements would be similar to the better-known "B. sessilis" var. "sessilis", but that this variety would be better suited to hotter, drier coastal areas.
