Backhousia citriodora (Lemon Myrtle)

Many ANBG guides surprise their groups following the main path by stopping at an otherwise unassuming small tree in the corner of Section 78. Only steps away are the much more fascinating rainforest gully in one direction and the iconic Wollemi Pine in the other. 

Yet this glossy elliptical-leaved tree with its profuse bunches of pretty centimetre-wide fluffy white flowers in summer offers many opportunities for the guide to spin a yarn or two—with a contemporary Canberra connection thrown in. There must be few plants in the Gardens better suited to explain so simply the otherwise bewildering logic behind the scientific naming of plants! 

We are before a part-grown tree, curiously out of place in Canberra’s winter, as opposed to its home range of the Queensland Coastal Rainforest. It would probably be happier in the nearby rainforest gully! Yet it thrives, even if nowhere near its natural height of up to eight metres. 

Long known, but even yet by no means fully exploited for its commercial potential, the leaves offer man a dual reward. The plant is well named in common parlance as Lemon Myrtle (also Lemon Ironwood). Its essential oils give a distinction to products like perfumes, cosmetics or even a bracing after-shave. Dried, the leaves are finding favour on supermarket shelves under its favoured common name.

It is about now the guide launches his or her spiel onto the unprepared visitor. Happily the plant is usually co-operative in having shed a leaf or two and laid them conveniently on the ground beneath. But first we have to do battle with the dreaded Latinised form of the very English name that gives itself to that of the genus. The wise, if enthusiastic, guide will skip trying to unpack the rules for turning English—or Greek or any other language—into Latin. He will do well just to take the botanists’ word for it. 

Backhouse? James Backhouse, born in Durham County in 1794, died 1869. The circumstances of his parents had already set the path for James’ life to unfold. They were wealthy Quakers. The Quaker in young James would call him to far places to bring a greater humanity to miserable people; the inherited wealth, supplementing that of other Quakers, would support that calling. But another leaf had yet to be written in the book of his life. 

He set out to be a chemist, even beginning an apprenticeship. But tuberculosis put paid to that and he looked for an outdoor avocation. To be a nurseryman seemed a good choice—and a fortuitous one for our ANBG visitors. 

Following training as a nurseryman he bought a nursery, with his brother, in York in 1816. 

Imbued with the Quaker philosophy of justice and humanity he, with a colleague, sailed for Australia in late 1831. In Hobart Town they began what for James would be a busy six years in Australia. Visiting convicts, remote settlers and Aboriginal communities in every state they produced a dozen reports—and far-reaching recommendations for reform. Among those Backhouse influenced was Alexander Maconochie, who would introduce a whole new regime of humanity when he arrived on Norfolk Island as Commandant in 1840. 

And the whole while James was collecting specimens of Australian flora to send back to Kew. For his diligence a new genus, with its handful of species, would be named for him as Backhousia. 

The guide is well into his or her story. But what about the citriodora? 

At this point one of those shed leaves takes centre stage. A quick crush by the guide and an invitation to smell the result completes the story.

The powerful lemon smell universally evokes the response ‘it smells just like lemon’. Citriodora — smells like! 

An unassuming plant beside the path offers a whole story : of a generous selfeffacing man, of a powerful description of a plant’s uniqueness, and of how we have those really logical names for plants. Nearly two centuries later Norfolk Island’s Alexander Maconochie, powerfully influenced by the humanity of the quiet Yorkshire Quaker, gives his name to the new ACT prison—claimed as the most advanced in the world for its humanity. 

What began with a nineteenth century Yorkshire nurseryman continues in twenty-first century Canberra. Motorists on the Monaro Highway pass the Alexander Maconochie Correctional Centre and wonder ‘Where does that name come from? What made him worth remembering?’ Visitors to the Australian National Botanic Gardens who imagined ahead nothing more than a quiet afternoon stroll have learnt how we name our plants,and probably a great deal besides.

All that in a totally unassuming plant with glossy leaves and fluffy white flowers in summer quietly growing beside the path

Geijera parviflora (Wilga - Family Rutaceae)


Photo by Anne Rawson


Downwards from the waterfall at the rock garden, at the Australian National Botanic Gardens (ANBG), across from the main path, on a corner, is a well established evergreen tree with long narrow leaves sweeping the ground. I am reminded of Dame Mary Gilmore (1865-1962) when I stand beside it. Among her published books were the Rue Tree (1930) and Under the Wilgas (1932). One of her poems begins: 

The Rue Tree is the tallest tree,
None other is so tall;
The Rue Tree is the smallest tree,
None other is so small.

Born in the nearby Goulburn district she became a pupil teacher at Wagga Wagga. As a child she had been a ‘sister’ of the Waradjery tribe for a short time.

The name Wilga appears in the Concise Australian Oxford Dictionary for a drought-resistant small tree or shrub especially Geijera parviflora of inland eastern-Australia from Wilgarr in the Wiradhura language.

The generic name Geijera (pronounced guy-jer-aj) honours J.D.Geija, a Swedish botanist, author of Diktamnographia (1687) and other works.

The specific name parviflora is Latin for ‘small flowers’.

The Wilga tree has many uses. It was valued by the Aboriginal people (see Wiradjuri Plant Use in the Murrumbidgee Catchment, compiled by Alice Williams and Tim Sides (2008)). Under the dense canopy of long aromatic leaves, small creatures could shelter and be a source of food. Wild bees made honey from the small flowers. The bark and roots made splints to treat broken bones, and boomerangs were made from the wood.

Rutaceae (the Rue family) is found in temperate and tropical regions worldwide, consisting of evergreen trees and shrubs, and often they are aromatic and of economic importance. Introduced citrus trees (oranges, limes, etc.) are cultivated. Ornamental boronias, correas, croweas, eriostemons, etc. are among our native shrubs here at the ANBG.

In Europe, in the Middle Ages, leaflets of the small leafed shrub were carried and used for sprinkling holy water on open wounds to ward off infection. It was called The Herb of Grace. Judges kept the bruised leaves on their benches when prisoners were brought before them for trial to counteract evil odours (hence the expression ‘to rue the day’).

In grazing paddocks, the foliage is often pruned by stock nibbling the leaves within reach to create a mushroom effect. A valuable fodder plant, the Wilga may be cut and fed to stock in drought time. It is useful for shade and shelter in large gardens, parks, farms, and roadsides. In California, it is known as the Australian Willow, and it is grown as a greenhouse plant in England.

Unfortunately, the seed is often unreliable to germinate and cuttings slow to propagate at present. 

The name is commemorated as a place name in Canberra in Wilga Place, O’Connor and Geijera Place, off Cunningham Place, in Kingston

A visitor to the ANBG once told me that a grateful farmer had named his newborn daughter Wilga, because this tree had saved prized sheep in drought time.

Another visitor — not to be outdone — thought that she recalled that a country woman of that name had once successfully won a competition to make a sponge cake in a microwave oven!

Wilga, a delightful, versatile Australian name.

A Tree of Grace, the Wilga tree.
Deserving widespread fame;
Drought-tolerant, sheltering, evergreen,
Delightful given name.
