Boronia duiganiae is a plant in the citrus family Rutaceae and is endemic to mountain ranges in south-east Queensland, Australia. It is an erect shrub with many branches, leaves with one, three or five leaflets, and pink to white, four-petalled flowers.

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".

Rutaceae family of plants

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

Endemism ecological state of being unique to a defined geographic location or habitat

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 duiganiae is an erect, many-branched shrub which grows to a height of 2.0 m (7 ft) with its young branches densely covered with white to yellow hairs. The leaves are pinnate with one, three or five leaflets and have a petiole 2–8 mm (0.08–0.3 in) long. The end leaflet is 6–31 mm (0.2–1 in) long and 3–12 mm (0.1–0.5 in) wide, the side leaflets smaller, 5–17 mm (0.2–0.7 in) long and 2.5–8 mm (0.1–0.3 in) wide. The leaflets are elliptic to lance-shaped, with the narrower end towards the base and their undersides are densely hairy. Up to three pink to white flowers are arranged in leaf axils on a hairy stalk 0.5–1 mm (0.020–0.039 in) long. The four sepals are egg-shaped to triangular, 3.5–5 mm (0.14–0.20 in) long, 2–3 mm (0.079–0.12 in) wide and hairy on their lower surface. The four petals are 6–11 mm (0.24–0.43 in) long, 3–6 mm (0.12–0.24 in) wide. The eight stamens are hairy. Flowering occurs from February to November and the fruit are 4–5.5 mm (0.16–0.22 in) long and 2–3 mm (0.079–0.12 in) wide. [2]

Petiole (botany)

In botany, the petiole is the stalk that attaches the leaf blade to the stem. Outgrowths appearing on each side of the petiole in some species are called stipules. Leaves lacking a petiole are called sessile or epetiolate.

Sepal part of a calyx

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 σκεπη (skepi), a covering.

Petal Part of most types of flower

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 duiganiae was first formally described in 1999 by Marco F. Duretto and the description was published in the journal Austrobaileya from a specimen collected near Rolleston. [1] The specific epithet (duiganiae) honours the Australian palaeobotanist Suzanne Duigan. [2]

Rolleston is a small town and locality in the Central Highlands Region, Queensland, Australia. In the 2011 census, Rolleston had a population of 129 people.

Botanical name scientific name for a plant (or alga or fungus) (ICNafp)

A botanical name is a formal scientific name conforming to the International Code of Nomenclature for algae, fungi, and plants (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the International Code of Nomenclature for Cultivated Plants (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae (Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups ."

Paleobotany branch of botany

Paleobotany, also spelled as palaeobotany, is the branch of paleontology or paleobiology dealing with the recovery and identification of plant remains from geological contexts, and their use for the biological reconstruction of past environments (paleogeography), and both the evolutionary history of plants, with a bearing upon the evolution of life in general. A synonym is paleophytology. Paleobotany includes the study of terrestrial plant fossils, as well as the study of prehistoric marine photoautotrophs, such as photosynthetic algae, seaweeds or kelp. A closely related field is palynology, which is the study of fossilized and extant spores and pollen.

Distribution and habitat

This boronia grows in woodland and forest on sandstone on the ranges south and south west of Rolleston and Springsure. [2]

Springsure Town in Queensland, Australia

Springsure is a town and a locality in the Central Highlands Region, Queensland, Australia. It is 66 kilometres (41 mi) south of Emerald on the Gregory Highway. It is the southern terminus of the Gregory Highway and the northern terminus of the Dawson Highway. It is 765 kilometres (475 mi) northwest of Brisbane. At the 2016 census, Springsure had a population of 1103.

Conservation

Boronia duiganiae is classed as "least concern" under the Queensland Government Nature Conservation Act 1992. [3]

The Nature Conservation Act 1992 is an act of the Parliament of Queensland, Australia, that provides for the legislative protection of Queensland's threatened biota.
