Better than Sudokus

Last week I was invited to participate in a weeding session at the Murchison Spur lookout. The Strath Creek Landcare Group had previously planted the area with native flora and in preparation for the upcoming weeding/clean up event on November 30 (hint, hint for those who have a couple of hours free) it was decided to prepare a model (weeded) area to highlight to the many eager weeders who undoubtedly will turn up, what is a native plant and what isn’t. Sometimes it’s difficult to tell.

DSCN4282How hard could it be? Well very hard actually. Forgetting about the occasional rain shower and the gale force winds I was assigned an area consisting primarily of ground creepers (pictured left). Intertwined on the ground were Running Postman (Kennedia prostrata) and Subterranean Clover (Trifolium subterraneum).

DSCN4289Separated, it is easy to distinguish between them. The former has red pea-shaped flowers (pictured right) and the latter white flowers. But mixed together they formed a puzzle more complex than the most devious Sudoku. DSCN4285The trick is that the leaves of each have a slightly different shape and the clover leaf has a light pattern on it (see left). It took hours to carefully separate the two and remove the clover.

So if the cryptic crosswords are getting too easy and the sudokus a breeze, November 30, 10am, Murchison Spur Lookout. If you really want a challenge.

One of these things is not like the other #2

I admire people who can walk through the bush and identify the flora without referring to a field guide. To do this I think you need a good knowledge of what flora should be in the area (that will whittle down the hundreds of choices down to the tens), and then a system for classifying them.

Cootamundra Wattle - easy peasy

Cootamundra Wattle – easy peasy

For nearly a decade I have been trying to learn all the plants on our property (with little success). I’ve started with the acacias. Acacias are divided into six groups based on the shape and form of the leaves and flowers. Using the colour of the flowers is not very helpful! Group 1 acacias contain wattles with bipinnate foliage (as opposed to single leafed). I call them feathery-leaved wattles. Where I live there are only three species with this type of leaf – the Cootamundra Wattle (Acacia baileyiana) (an environmental weed in this area, planted by the previous owner), the Silver Wattle (Acacia dealbata) and the Black Wattle (Acacia mearnsii).

Silver Wattle - a bit trickier

Silver Wattle – a bit trickier

The Cootamundra is easy to pick – SMALL bipinnate leaves and that unique light blue-green colour. The Silver and the Black Wattles are a bit trickier to tell apart. The Silver Wattle flowers a bit earlier but how do you pick them when they are both in flower or both not? I’m glad you asked. You will have to look closely at the rhachis – the stem down the centre of the leaf. Distributed along the rhachis are tiny oil glands. In the Silver Wattle the oil glands are situated AT the point where each pair of pinnates is attached to the stem (pictured above). In the Black Wattle, those oil glands are BETWEEN the spot where the individual fronds meet the stem (pictured below, click photo to enlarge). Tricky, eh?

Black Wattle

Well, that covers the bipinnate wattles. That only leaves 11 more acacia species and several dozen more trees to come to grips with.

One of these things is not like the other one #1

A decade ago we moved up from the city to live in the bush. Looking back we were naïve and idealistic with a vision of removing all the weeds and exotic plants from the property. Every year we would target one or two species with mixed success. All the Cotoneasters are gone as is the Broom, English Ivy and French Lavender. The thistles and blackberry are on their last legs. The journey however has been fraught with blunders.

Yam Daisy

Very early on we targeted a plant thinking it to be a weed and spent hours pulling it out. Unfortunately it was native – various species of Senecio or Fireweed. Fortunately our clumsy attempts to eradicate the plants failed dismally and they made a brilliant recovery. There are however many such identification traps for the unwary. With similar flowers, one confusion is between the Yam Daisy or Native Dandelion (Microseris lanceolata) and the Dandelion (Taraxacum sp.), a weed native to Europe and Asia.

Yam Daisy - note leaves and drooping buds

Yam Daisy – note leaves and drooping buds

Since the fires in 2009, Yam Daisies have been appearing throughout the bush. This species has roots that Indigenous people baked and ate. Unusually, the buds droop on the end of long stalks, which become erect when in flower to attract the pollinating insects. After pollination the stalks again droop only to become erect again when seed heads ripen, presumably to catch the best breeze for seed dispersal.

If you can’t wait the plant’s entire life-cycle to check if your flower is a Yam Daisy and not a Dandelion, look at the leaves. The Yam Daisy has narrower toothed leaves that stand

up off the ground whereas the dandelion has broader leaves that form a rosette on the ground. In the end both plants produce showy yellow flowers but for the purists among us that isn’t enough.

Beware of imitations

It is a global economy. When you purchase something it is difficult to tell if it is the real Aussie deal or an imported imitation.

Let’s talk Plantains (not the banana-type of plantains). Plants in the Plantago genus are commonly called plantains. They are inconspicuous and are found all over the world. Locally one of the most common native plantains is the Variable Plantain (Plantago varia).

Plantation of Plantago varia

Each spring this plant is first seen as rabbit-ear-type leaves come out of the ground. The flowers are brown cylindrical spikes and even though they do not have the amazing colours of the orchids, lilies and peas we have blogged about recently, in close-up they are a wonder of detail (see picture below). DSCN3871The prominent anthers can be seen on the end of thread-like filaments. Variable plantain colonises undisturbed areas—so they are most common on ungrazed land and along some of the natural roadside reserves. They do not attract birds or frogs but are a food plant for caterpillars.

One of the more common imported species from the same family is Ribwort (Plantago lanceolata). You will probably recognise it by the flower-head pictured below. As kids we used to make missiles of the flower head by rapidly pulling the stalk through a bent stem. This garden weed is a native of Europe and Central Asia and is commonly found in more disturbed sites such as cuttings and road edges. Ribwort also is a favoured food source of butterfly and moth larvae.

But if you are after a genuine Australian plant you can’t go past Plantago varia. As Australian as Vegemite.

Rare find on the hill

One of the things I love about living close to Mother Nature is that things constantly change. If I go for a walk I’m never sure what I’ll find (click HERE to view related blog). It’s just a matter of keeping our eyes open. Sometimes there will be a new bird or animal. Other times a patch of ground over which I have walked a thousand times will yield a new plant.

DSCN3556And so it was last week. On my regular stroll around the place I noticed something I hadn’t noticed before — a ground creeper with purple pea-shaped flowers atop 6-cm stalks (pictured above). The leaves looked like that of a glycine. Local enthusiasts suggested the plant to be Clover Glycine (Glycine latrobeana), ANOTHER member of the extensive Pea family discussed in a previous blog (click HERE to view). We had already identified two other species of glycine on the property including Twining Glycine (Glycine clandestina), which is also flowering at the moment. The difference is G. latrobeana is listed as Vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and Threatened under Victoria’s Flora and Fauna Guarantee Act 1988. According to the Victoria Biodiversity Atlas, ours is the first recorded sighting of this plant in the Murrindindi Shire and one of only ten sightings in the Goulburn–Broken Catchment. The plant even has a National Recovery Plan (click HERE to view) which includes conservation methods, recovery actions and biodiversity benefits. As a precaution we have placed a cage around it to prevent it from becoming something’s lunch. (From the rabbits, not the local vegans.)

We are now awaiting positive identification from the experts, but have already had requests for some of the seed. In anticipation of a positive ID I have already ordered the razor wire and surveillance cameras and have started digging the machine-gun emplacements. The responsibility is weighing heavily.

Move over lilies—here come the orchids

There is a certain mystique about orchids. For me it is the fantastical, almost alien shapes and stunning colours. As a kid my father used to grow tropical orchids in a gas-heated glass house in the backyard. When they flowered he used to give them away to the neighbours. He was the toast of the town.

Orchids are one of the two largest families of flowering plants in the world. There are more than 800 species of Australian orchids, most of them only found in this country—and there are more discovered each year. During the drought and pre-bushfire years the number of native ground orchids we found on our property you could count on the fingers of one hand. However since the rains and fire that number has dramatically increased. This year looks like it will be a bumper year, if the number of orchids leaves popping out of the ground is any indication.

DSCN3568 - CopyThe first to raise its head this season is the Green-comb Spider Orchid (Arachnochis dilatata), pictured above. It was previously known as Caladenia dilatata. The photo shows the origin of the name—green comb-like structures on either side of the flower. The Indigenous name is koolin, and its tubers are considered a food source.

In the upcoming weeks the orchids will start flowering (if the rabbits don’t get them first). As showy as the lilies are at the moment, for me the orchid reigns supreme.

P.S. On my walk around the property before the Grand Final opening bounce, I spied a touch of purple (maybe an omen for Freo). For the first time ever, a Wax-lip Orchid (Glossodia major), see below. DSCN3582 - Copy

Grand Final special – the Purple Haze descends

Some of you may not be aware that last weekend, the Fremantle Dockers AFL team qualified for their first Grand Final, to be played on Saturday. The main colour of the jersey is purple and to their fans the team is affectionately known as the ‘Purple Haze’. Looking up at the spur above our house at the moment you could be forgiven for thinking I have forsaken the West Coast Eagles and jumped onto the Freo band-wagon. (Those of you who have visited Western Australia will realise that this is slightly more ridiculous than a Carlton fan supporting Collingwood). It appears a purple haze has descended on the hill above our house.

The colour is due to a stand of trees which are a particular cultivar of the Cootamundra Wattle known as Acacia baileyana purpurea. In Spring A. baileyana produces new growth that is light green in colour (see photo below) whereas this cultivar produces new foliage that is purple in colour, REALLY purple (see photo left). With all the branches tipped with purple foliage it looks like there is a  purple mist on the hill.

Like the normal Cootamundra Wattle, A. baileyana purpurea is classed as an environmental weed in the Murrindindi Shire and should be removed.

Maybe I’ll wait until after the Grand Final. I’ll be busy this weekend watching the footy. Go Freo.

All Hail the King

Now I’m REALLY embarrassed. After all the fuss made recently about the existence of the Australian King Parrot (Alisterus scapularis) (click HERE to view), the creature after which the local creek and hence this environmental group was named, guess what should show up at our place for the first time ever. Yep, the very same.DSCN3433 - Copy

Mr and Mrs were not very scared and were obviously looking for some hand-outs for dinner. Needless to say they left with nothing (we don’t feed wildlife) but they did brighten up an otherwise dreary, rainy, seven-degree day.DSCN3438

I AM a believer. Long live the King!

May Peas be with you

The Fabaceae family of plants is named after the Latin word faba meaning bean. It refers to the shape of the fruits of these plants. Fabaceae are the third largest family of land based plants after those containing orchids and daisies. You know Spring is almost here when the species with pea-flowers start to blossom. Over the past month several species have appeared.

DSCN3411False Sarsparilla or Purple Coral Pea (Hardenbergia violacea), pictured left,  is hard to miss. The deep-purple flowering vine is very conspicuous on steep slopes and climbing up trees and shrubs.

DSCN4822Common Hovea (Hovea linearis), pictured right, has been flowering for a couple of month now. It is a ground creeper with blue-purple flowers.

austral indigoAustral Indigo (Indigofera australis) has pink-purple flowers. Traditionally the leaves were crushed and added to water to kill eels and fish. Its leaves produce a yellow dye.

_MG_5330Narrow-leaf Bitter Pea (Daviesia leptophylla) is pictured right. At least it’s not purple.

Watch for these in your travels and let peas be with you.

Week 35 – Now showing in a locale near you

With spring approaching all sorts of things are starting to pop up. In week 35 of this calendar year some things that have been observed for the first time this season up on Junction Hill are:

Early Nancys (Wurmbea dioica) (see previous post) – first lily bloom

Keep your eyes peeled. With the start of warmer weather everything is beginning  to reveal itself.
