Boronia tolerans is a plant in the citrus family, Rutaceae and is endemic to a small area in the Northern Territory in Australia. It is an erect shrub with many branches, pinnate leaves and white, four-petalled flowers. It is only known from Nitmiluk National Park.

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 tolerans is an erect, much branched shrub that grows to a height of about 50 cm (20 in). The leaves are arranged in opposite pairs, pinnate, sessile with mostly five or seven leaflets and 7–50 mm (0.28–1.97 in) long and 8–17 mm (0.31–0.67 in) wide in outline. The end leaflet is linear to narrow elliptic, 8–25 mm (0.31–0.98 in) long, 1–2.5 mm (0.039–0.098 in) wide and the side leaflets are 5–16 mm (0.20–0.63 in) long, 1–2 mm (0.039–0.079 in) wide. The flowers are arranged singly in leaf axils on a pedicel 1–2 mm (0.039–0.079 in) long. The sepals and petals are white, the four sepals triangular to egg-shaped, 4–5 mm (0.16–0.20 in) long and about 1.5 mm (0.059 in) wide but increase in size as the fruit develops. The four petals are 3.5–5 mm (0.14–0.20 in) long but increase in size as the fruit develops. There are eight stamens and the style is glabrous. Flowering occurs from March to June. [2] [3] [4]

Sessility (botany)

In botany, sessility is a characteristic of plant parts that have no stalk. Flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of most monocotyledons lack petioles.

Pedicel (botany)

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".

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.

Taxonomy and naming

Boronia tolerans was first formally described in 1997 by Marco F. Duretto who published the description in the journal Nuytsia . [5] The specific epithet (tolerans) is derived from Latin tolerans, meaning "tolerant", referring to "the great mental hardship suffered by Dr Greg Howell on the day this species was collected in the field." [3]

Nuytsia is a peer-reviewed scientific journal published by the Western Australian Herbarium. It publishes papers on systematic botany, giving preference to papers related to the flora of Western Australia. Nearly twenty percent of Western Australia's plant taxa have been published in Nuytsia. The journal was established in 1970 and has appeared irregularly since. The editor-in-chief is Kevin Thiele.

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 ."

Latin Indo-European language of the Italic family

Latin is a classical language belonging to the Italic branch of the Indo-European languages. The Latin alphabet is derived from the Etruscan and Greek alphabets and ultimately from the Phoenician alphabet.

Distribution and habitat

This boronia grows in woodland on the top of the plateau in the Nitmiluk National Park. [4] [3]

Conservation status

Boronia tolerans is classified as "near threatened" under the Territory Parks and Wildlife Conservation Act 2000 (TPWCA). [4]
