Boronia stricta is a plant in the citrus family, Rutaceae and is endemic to near-coastel areas of the south-west of Western Australia. It is a slender shrub with often crowded pinnate leaves with linear leaflets, and pink, four-petalled flowers borne singly or in groups of two or three in leaf axils.

Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

The Rutaceae are a family, commonly known as the rue or citrus family, of flowering plants, usually placed in the order Sapindales.

Endemism is the ecological state of a species being unique to a defined geographic location, such as an island, nation, country or other defined zone, or habitat type; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. The extreme opposite of endemism is cosmopolitan distribution. An alternative term for a species that is endemic is precinctive, which applies to species that are restricted to a defined geographical area.

Description

Boronia stricta is a slender shrub that grows to a height of 2 m (6 ft 7 in) with long soft hairs. The leaves are pinnate with between five and nine leaflets and 10–20 mm (0.39–0.79 in) long, the leaflets linear to almost cylindrical and up to 15 mm (0.59 in) long. A single or two or three pink flowers are borne in leaf axils, each flower on a hairy pedicel 2–5 mm (0.079–0.197 in) long. The four sepals are narrow triangular, 3–7 mm (0.12–0.28 in) long and hairy. The four petals are broadly elliptic, 5–9 mm (0.20–0.35 in) long and pink with a dark midline. The eight stamens are about 2 mm (0.079 in) long with the four stamens nearer the sepals swollen with a warty tip. The style is club-shaped. Flowering mainly occurs from September to December.^[2]^[3]

A pedicel is a stem that attaches a single flower to the inflorescence. In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the latin pediculus, meaning "little foot".

A sepal is a part of the flower of angiosperms. Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. The term sepalum was coined by Noël Martin Joseph de Necker in 1790, and derived from the Greek σκέπη, a covering.

Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla. Petals are usually accompanied by another set of special leaves called sepals, that collectively form the calyx and lie just beneath the corolla. The calyx and the corolla together make up the perianth. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term tepal is appropriate include genera such as Aloe and Tulipa. Conversely, genera such as Rosa and Phaseolus have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they include Liliales, an alternative name is lilioid monocots.

Taxonomy and naming

Boronia stricta was first formally described in 1845 by Friedrich Gottlieb Bartling and the description was published in Plantae Preissianae .^[4]^[5]

Friedrich Gottlieb Bartling German botanist

Friedrich Gottlieb Bartling was a German botanist who was a native of Hanover.

Plantae preissianae sive enumeratio plantarum quas in australasia occidentali et meridionali-occidentali annis 1838-1841 collegit Ludovicus Preiss, more commonly known as Plantae preissianae, is a book written by Johann Georg Christian Lehmann and Ludwig Preiss.

Distribution and habitat

Boronia stricta grows in swampy areas between Margaret River, the Stirling Ranges and Albany in the Esperance Plains, Jarrah Forest and Warren biogeographic regions.^[2]^[3]

Margaret River is a town in the South West of Western Australia, located in the valley of the eponymous Margaret River, 277 kilometres (172 mi) south of Perth, the state capital. Its Local Government Area is the Shire of Augusta-Margaret River.

Albany is a port city in the Great Southern region in the Australian state of Western Australia, 418 km southeast of Perth, the state capital. Albany is the oldest colonial settlement in Western Australia, predating Perth and Fremantle by over two years.

Esperance Plains, also known as Eyre Botanical District, is a biogeographic region in southern Western Australia on the south coast between the Avon Wheatbelt and Hampton regions, and bordered to the north by the Mallee region. It is a plain punctuated by granite and quartz outcrops and ranges, with a semi-arid Mediterranean climate and vegetation consisting mostly of mallee-heath and proteaceous scrub. About half of the region has been cleared for intensive agriculture. Recognised as a bioregion under the Interim Biogeographic Regionalisation for Australia (IBRA), it was first defined by John Stanley Beard in 1980.

Conservation

Boronia stricta is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.^[3]

The Department of Parks and Wildlife (DPaW) was the department of the Government of Western Australia responsible for managing lands described in the Conservation and Land Management Act 1984 and implementing the state's conservation and environment legislation and regulations. The minister responsible for the department was the Minister for the Environment.
