Boronia warrumbunglensis is a plant in the citrus family Rutaceae and is endemic to a small area in the central west of New South Wales. It is a shrub with many branches, pinnate leaves and one or two pink, four-petalled flowers in the leaf axils. It is only known from the Warrumbungles and nearby districts.

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 warrumbunglensis is a shrub that grows to a height of 0.3–1 m (1–3 ft) and has many hairy branches. The leaves are pinnate with three, five or seven leaflets and are 6–32 mm (0.2–1 in) long and 2–27 mm (0.08–1 in) wide in outline with a petiole 3–6 mm (0.1–0.2 in) long. The leaflets are elliptic to lance-shaped, 5–16 mm (0.2–0.6 in) long and 1.5–3 mm (0.06–0.1 in) wide. The flowers are pale to bright pink and are arranged singly or pairs in leaf axils, each flower on a pedicel 3–7 mm (0.1–0.3 in) long. The four sepals are triangular to egg-shaped, 2.5–3.5 mm (0.098–0.14 in) long, 1.5–2 mm (0.059–0.079 in) wide and densely hairy on the lower side. The four petals are 5–6 mm (0.20–0.24 in) long and 2.5–3 mm (0.098–0.12 in) but increase in size as the fruit develops. The eight stamens alternate in length with those near the sepals longer than those near the petals. Flowering occurs from August to October and the fruit is a hairy capsule 5–6 mm (0.20–0.24 in) long and 3–3.5 mm (0.12–0.14 in) wide. [2] [3] [4]

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.

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 warrumbunglensis was first formally described in 1990 by Peter H. Weston and the description was published in Telopea . [1] [3] The specific epithet (warrumbunglensis) refers to the restricted occurrence of this boronia, the ending -ensis is Latin suffix meaning "denoting place, locality, country". [3] [5]

Telopea is a fully open-access, online, peer-reviewed scientific journal that rapidly publishes original research on plant systematics, with broad content that covers Australia and the Asia-Pacific region. The journal was established in 1975 and is published by the National Herbarium of New South Wales, Royal Botanic Gardens & Domain Trust. As from Volume 9, part 1, 2000, full text of papers is available electronically in pdf format. It is named for the genus Telopea, commonly known as waratahs.

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 forest on sandstone in the Warrumbungles - Coonabarabran district. [2]
