Xanthorrhoea quadrangulata

Xanthorrhoea quadrangulata or the Mount Lofty Grass Tree [1] is a plant in the genus Xanthorrhoea . It is the only species of Xanthorrhoea solely endemic to the state of South Australia. [2] [3]

Contents

Description

A very slow growing plant with a thick rough trunk and blue-green foliage. In the wild, this trunk is often burnt black as a result of fire. The trunks are capable of reaching 2 m length or greater, and are frequently branched. Typical of the trunked species of Xanthorrhoea, this species is extremely slow growing, increasing in height by only 2–3 cm per year on average. [4] [5]

Blooms occur irregularly from winter to spring, producing flower spikes between 1 and 3 m in height. These spikes bear small, nectar rich flowers, and are a source of food for nectar eating birds and butterflies. [6]

Distribution

This plant occurs broadly occurs throughout the Mount Lofty Ranges, with its range extending into the Flinders Ranges. It frequently inhabits rocky sites and ridges, and is particularly tolerant of clay soil. [7]

<i>Xanthorrhoea</i> Genus of flowering plants

Xanthorrhoea is a genus of about 30 species of succulent flowering plants in the family Asphodelaceae. They are endemic to Australia. Common names for the plants include grasstree, grass gum-tree, kangaroo tail, balga, yakka, yamina (Tasmania), and black boy. The most common species is Xanthorrhoea australis, and some of these names are applied specifically to this species.

<i>Kingia</i> Genus of trees

Kingia is a genus consisting of a single species, Kingia australis, and belongs to the plant family Dasypogonaceae. The Aboriginal name bullanock is used as a common name for the plant. It has a thick pseudo-trunk consisting of accumulated leaf-bases, with a cluster of long, slender leaves on top. The trunk is usually unbranched, but can branch if the growing tip is damaged. Flowers occur in egg-shaped clusters on the ends of up to 100 long curved stems. Kingia grows extremely slowly, the trunk increasing in height by about 1½ centimetres per year. It can live for centuries, however, so can attain a substantial height; 400-year-old plants with a height of six metres are not unusual.

<i>Prasophyllum</i> Genus of flowering plants

Prasophyllum, commonly known as leek orchids, is a genus of about 140 species of flowering plants in the orchid family, Orchidaceae and is found in Australia and New Zealand. The Australian species are found in all states but have not been recorded in the Northern Territory. The common name arises from their having a hollow, leek- or onion-like leaf. Some species only flower after summer fires and have flowers similar to those of Xanthorrhoea which flower at the same time, suggesting that they employ the same pollinating insects. Leek orchids are similar to those in the genus Genoplesium except that the free part of the leaf is cylindrical and the labellum has a solid connection to the column. They range in size from the little laughing leek orchid at about 15 cm (6 in) to the king leek orchid which grows up to 2 m (80 in) tall.

<i>Banksia seminuda</i> Species of tree in the family Proteaceae found in south west Western Australia

Banksia seminuda, commonly known as the river banksia, is a tree in the family Proteaceae. It is found in southwest Western Australia from Dwellingup (32°42′ S) to the Broke Inlet east of Denmark (34°57′ S). It is often mistaken for, and was originally considered a subspecies of, the Banksia littoralis. Stephen Hopper described the subspecies remanens as a short-leaved shrubby form found in the coastal sands below granite outcrops in the Walpole-Nornalup National Park. However, George does not feel this form warrants taxonomic recognition as it lies within the normal variability of the species and there was no clear distinction between it and the other populations of B. seminuda.

<i>Xanthorrhoea australis</i> Species of plant

Xanthorrhoea australis, the grass tree or austral grasstree, is an Australian plant. It is the most commonly seen species of the genus Xanthorrhoea. Its trunk can grow up to several metres tall and is often branched. In certain Aboriginal languages, it is called bukkup, baggup or kawee.

Acacia gunnii grows to up to 1 metre high and has prickly phyllodes which are 4 to 15 mm long.
