Conospermum acerosum, commonly known as needle-leaved smokebush, [1] is a shrub endemic to Western Australia
It grows as a spindly shrub, either erect or sprawling, from 0.3 to 1.7 metres (10 to 70 in) high, usually with several unbranched stems growing from the base of the plant. It has slender, needle like leaves up to 10 centimetres (4 in) long, and dense panicles of white, red or pink flowers, each about 8 millimetres (0.3 in) long. [1] [2] [3]
It was first published in John Lindley's 1839 A Sketch of the Vegetation of the Swan River Colony , based on specimens collected by James Drummond. Lindley referred to it as a "strange species" that "might be mistaken for a Colletia." [4] It has since had a thoroughly uncomplicated taxonomic history, with no nomenclatural or taxonomic synonyms published. [5] In 1995, however, as part of her treatment of Conospermum for the Flora of Australia series of monographs, Eleanor Bennett published a subspecies, C. acerosum subsp. hirsutum, based on material collected in 1901 by geologist and archaeologist William Dugald Campbell; thus the autonym C. acerosum subsp. acerosum was also invoked. [6] [7] C. acerosum subsp. acerosum has fine red hairs around the flowers and glabrous stems; subspecies hirsutum has fine hairs on the younger stems and leaf bases.
It occurs in sandy soil, often over laterite, from the Murchison River south to Cape Leeuwin; thus it occurs mainly within the Geraldton Sandplains and Swan Coastal Plain biogeographic regions, with some populations in the Avon Wheatbelt and Jarrah Forest regions. Its Flora of Australia entry, published in 1995, states that "there is also one doubtful collection from Norseman", but this is not (or is no longer) recorded within the West Australian Herbarium's FloraBase database. [1] [2]
It is not considered threatened. [1]
Banksia nobilis, commonly known as the golden dryandra, great dryandra or kerosene bush, is a shrub of the family Proteaceae which is endemic to Western Australia. It occurs on lateritic rises from Eneabba to Katanning in the state's Southwest Botanic Province. With large pinnatifid leaves with triangular lobes, and a golden or reddish pink inflorescence, it is a popular garden plant. It was known as Dryandra nobilis until 2007, when all Dryandra species were transferred to Banksia by Austin Mast and Kevin Thiele. There are two subspecies, B. nobilis subsp. nobilis and B. nobilis subsp. fragrans.
Banksia proteoides, commonly known as king dryandra, is a shrub endemic to Western Australia. It was known as Dryandra proteoides until 2007, when all Dryandra species were transferred to Banksia by Austin Mast and Kevin Thiele.
