General Description: 

Banksia rosserae is a recently (2002) named species which was only discovered in 2000. It is a bushy shrub to about 3-5 metres tall with leaves that are broadly elliptical with toothed margins to about 50-120 mm long. In its natural habitat, B rosserae apparently only flowers after significant rain and may therefore not flower for several seasons during extended dry periods. It was observed in flower for the first time in June 2006. The obovoid inflorescences are unusual in that they are pendulous on short lateral branchlets, a feature shared by only a few other species (eg. B.aculeata, B.caleyi, B.lemannianaB.nutans). The inflorescences are greenish-yellow to yellow in bud and, at maturity, are up to 50-60 mm in diameter and lemon-yellow in colour. The seeds are enclosed in follicles attached to a woody cone and are generally retained within the cone until burnt.

The species develops a lignotuber and is should be able to regenerate vegetatively after a fire, in addition to regeneration from seed.

Because of the scarcity of propagating material, Banksia rosserae has received only limited cultivation to date. It is a particularly attractive species that should be suitable for drier climates but will likely be difficult to maintain in humid areas such as the east coast of New South Wales and Queensland.

Propagation from seed is reported to be reliable either without pre-treatment or after treating with smoked water. Cuttings may be successful but have not been seriously tested at this stage.

Search Tips

By default the search engine tries to locate pages which have exact matches for all of the words entered in your search query. If that fails, it then tries to locate pages which contain any words in your search query. If that happens a short message is displayed at the top of the search results indicating this has been done. In addition, there are several ways to modify the default search behavior.  Note, searches are case insensitive.

Phrase Search
The search engine supports three types of phrase search.

  • To match an exact phrase, use quotes around the phrase. Example: "banksia integrifolia"
  • To match a near (within a couple of words) phrase, use square brackets [around the words]. Example: [banksia integrifolia]
  • To match a far (within several words) phrase, use braces { around the words }. Example: {banksia integrifolia}

+ and - qualifiers
If you prepend a word with + that word is required to be on the page. If you prepend a word with - that word is required to not be on the page. Example: +always -never

* Wildcard
If a query word ends with a * all words on a page which start the same way as that query word will match. Example: gift*

? Wildcard
If a query word contains a ? any character will match that position. Example: b?g

Boolean Search
You can use the following boolean operators in your search: AND, OR, NOT. These operators MUST be in capital letters. Example: (contact AND us) OR (about AND us)

All of these techniques can be combined: +alway* -ne??r*
