There are 29 Fabiaceae species in Foxes Lair and many others in the district. 
They all have five petals whose shape has evolved specifically for pollination by native bees.

• The large top petal called a banner usually has a differently coloured 'bullseye patch' at its base, which attracts the bee to a nectar gland is. Because bees can see ultraviolet light, the bullseye patch stands out even more for them than for us. For more information see this paper.

• ​Below this, two sideways- aligned petals called wings project out as a landing point, and cover the stamens and pistil.
• Under the stamens and pistil is the keel, which consists of two petals, joined to form a boat - shaped base to stop insects getting at them for below.

There is a range of flower sizes, which would fit a number of pollinators, but they are all designed for the bee to land on the flower from the front. The bee's claws push the wings down  and the bee's abdomen contacts the pistil and stamens. Megachile bees have furry tummies, which then collect  pollen.
European honey bees don't play by the rules. They often steal nectar from the side of the flower. I recently saw honey bees chewing into Daviesia flowers before they had opened. The bees destroyed flowers and ate the pollen. With their overwhelming numbers, they reduce pollination and native bee numbers.

Kennedia prostrata (Running Postman) is an oddity, and one of the first plants to recolonise in the season following a bushfire.
The plant can form cluster roots  enables it to extract phosphorus from organic souces such as charcoal.
The large red flower is designed for bird pollination, presumably because birds colonise burnt areas before insects. Unlike other pea flowers,the wings don't cover the keel allowing a honeyeater to accurately place its beak  to get nectar and pollinate the flower.

Here are some other local Fabeaceae.

As a boy I remember  itinerent flower sellers coming to our house with bunches of heavenly smelling Boronia metastigma. I recently learnt that the intense aroma is a strategy to attract  a particular pollinator - a heliozelid moth. The moth pollinates the flower while laying eggs on the carpels (ovaries). Caterpillars eat some but not all ovaries, so win win for plant and moth.
Boronias are in the Rutaceae family, which is characterised by open flowers with a superior ovary and leaves containing oil glands.Our domesticated citrus plants are in this family.
Boronias have opposite leaves and  four sepals and petals.
Recently Boronias have been split into two genera:- Boronia and Cyanothamnus. There is almost no physical difference between the genera. Two different genetic groups have evolved very similar plant features. A trifle perplexing for the amateur, but such is modern taxonomy.

When I moved to Narrogin, I was amused to find tiny Cyanothamnus ramosus flowers in Foxes Lair. Local Boronia / Cyanothamnus species are mainly pink/ white or pale blue colours with little scent. Unlike us, Insects see untraviolet light and these colours are exceptionally bright for them. Several native bee species pollinate these boronias. 
Male and female parts are clustered together in a tight group. Images of Cyanothamnus ramosus below show that a barrier of serrated stamen filaments with coarse hairs prevent insects from accessing nectar from the side. My guess is that these stop ants and other nectar thieves. To get nectar, insect pollinators have to poke their tongue down the top of the flower past the clustered anthers and stigma. To avoid self pollination, the stigma only becomes receptive after the flower's pollen has died.

The dissection of Boronia capitata subsp. capitata shows dense stamen hairs, which exclude nectar thieves.

There are several mostly pink or white coloured Boronia /Cyanothamnus species in this district. 

Two other genera in this district differ from boronias by having alternate leaves and five sepals / petals.
They look very similar.
Asterolasia pallida (white) and squamaligera (yellow) have a tiny or no sepals and petals with a hairy exterior.
Phebalium tubercolosum (white) and filifolium (yellow) are showy shrubs commonly found in mallee woodland in the east of the district. Sepals are smaller than petals, and petals have a scaly or scurfy exterior.

Sedges and rushes  are not the most exciting plants in our bush, but they are an important part. These plants protect the soil from erosion and are important habitat plants for insects, spiders, larger animals, and birds. They become obvious on misty mornings when each one becomes a dewy spider palace. Before European settlement, these plants were habitat and food for numerous emus, small rodents and marsupials, which are locally extinct. Rushes and sedges are still important habitat in wetlands. Western Grey Kangaroos and even foxes nibble sedge leaves.

​I am writing this blog for myself because descriptions and common names for this group are confusing.

A commonly used rhyme to distinguish between grasses, sedges, and rushes is.
“Sedges (Cyperaceae) have edges, rushes (Juncaceae)  are round, grasses (Poaceae) have knee joints all the way to the ground”.
This rhyme is not useful in WA.

Does it matter if you can't tell the difference? Occasionally yes when weeds are involved. A recent example was a decision to replace Bull Rushes in Narrogin Creek with Common Reed Phragmites Australis, which is an introduced weed. Phragmites is certainly impressive and probably isn’t a problem there apart from blocking the creek, but it kills adjoining plants and is an aggressive weed in coastal wetlands.

Here are my local rules of thumb.

Grasses (Poaceae), sedges (Cyperaceae), rushes (Juncaceae) and southern rushes (Anarthriaceae and Restionaceae) are all wind pollinated monocotyledons, which grow as annuals or clumping perennials. Perennial plants spread by horizontal underground roots called rhizomes.
​
There are lots of native and introduced grasses around, which can be easily identified  by their hollow stems and stem joints called nodes.

​Sedges and rushes don’t have nodes, usually have solid pithy stems, and their leaves arise from a rhizome near the ground. Wetland species commonly called rushes may actually be sedges or grasses. For example, Bull Rush or Cumbungi / Typha species are wetland grasses. Cumbungi is a bush tucker plant, which I decided to taste recently in the spirit of citizen science. Chewing a peeled rhizome was less than successful, so I cooked some in the microwave. Result: Texture = rope, taste = blah! Perhaps I should have collected my sample in the growing season and not from a roadside ditch. When I first came to Narrogin, Cumbungi groves formed wonderful bird nesting areas in Railway Dam. Our drying climate has almost eliminated them now.

Locally, the classic round, smooth-leaved rushes are mostly weeds. Toad Rush  Juncus bufonius is a tiny annual weed which was a problem in wet areas in crops before no-till farming.
Spiny Rush Juncus acutus is an introduced spiny weed, which infests our damp waterways and dams. Despite this it is useful for reducing erosion in wet salty areas, and as wildlife habitat.
​

​Sedges may have flat or angled leaves (‘edges”) or not. I have noticed that flat-leaved species tend to be larger plants, which occur more often in winter wet/summer dry areas on slopes and flats. Flowers are often surrounded by spiky bracts and each produces a single small nut.

Schoenus species are small narrow-leaved sedges. Ground-hugging Schoenus calcaratum would be a delightful addition to the native garden.

A special group In southwestern WA is called southern rushes. Unlike sedges and rushes, they are dioecious (have male and female plants). There are two families, Anarthriaceae (mainly near to the coast), and (local) Restionaceae.
Restionaceae are funky mat-like plants with round green to grey-green stems (culms),and brownish scale leaves, which often occur in patches in open kwongan or woodland. Being very tough plants which can withstand short-term waterlogging then drought, they are often found on open gravel, sand,or sand over clay.
​
Lepidobolus species have curly snake-like culms

Desmocladus species have branched culms and female plants with leaf sheaths that sprout clusters of short stalks each with a single flower, which make them look like branched leaves.

​Ericaceae, also called the Heath Family is common on acidic sandy and gravelly (particularly kwongan) soils. Flowers are often small, but exquisitely shaped.
Common features include.

• Prostrate or low shrubs, usually having short tough leaves with parallel leaf veins and a sharp tip.
• Flowers have free sepals surrounding petals, which are fused into a short or long tube ending in petal lobes that may be shorter or longer than the tube.
• Usually white or red/orange flowers with nectar. but may or may not have an aroma.
• Flowers often have tiny hairs or scales on upper petal surfaces on the lobes and/or inside the tube. Incidentally, these hinder non-pollinating insects such as ants from stealing nectar.
• Fruit are berries (drupes) or small capsules, which are eaten by animals. Emus are listed as major seed dispersers.
• Many of them flower early in the year from March onwards.

​Recently there has been an amalgamation of species based on shared genes from DNA analysis. The two largest genera, Astroloma and Leucopogon have been absorbed into Styphelia. These in turn belonged to mostly Western Australian family named Epacridaceae, which has been amalgamated into the formerly mostly eastern states plant family Ericace.
I can see the logic behind genetic grouping, and have a high regard for our Eastern States neighbours (despite them being a trifle strange).
However, it is rather sad for people like me with an flawed memory and even less patience to work my way through a tortuous key to identify plants with shared characteristics.

Historically, classification was based totally on shared plant features. At genus level, flower characteristics have been shaped by evolution to attract particular pollinators.
Here are a few examples.

• Colour. Insect vision is sensitive to ultraviolet and white light, but poor at the red end of the spectrum. Conversely, red stands out for birds and large animals, which are major pollinators)
• Sexual deception in orchids.
• Plants like Hibbertias and tomatoes lack nectar, but have dry loose pollen which attracts bees that use buzz pollination.
•  Plants with nectar and very long petal tubes selectively attract moths and birds. Those with short or no tube are generalists which can be pollinated by many animals including flies.
• Mammal specific flowers are often large, hidden, dull-coloured, and strongly scented with lots of nectar.

In older papers I noticed that the old genera often had different pollinators due to flower shape and colour. To me this is much more interesting than a huge genetic genus
​.
At risk of being labelled a dinosaur, I list local Ericaceae genera below using the old classification so I can easily distinguish plant groups  having shared characteristics in the bush. Some other amateurs may find it useful.​

Genus Lysinema (unchanged)
Flowers of the most common species called Curry Bush have a curry powder smell, which attracts pollinating moths. Flowers have several distinctive brown bracts, which cover most of the white flower tube. Formerly classified as Lysinema ciliatum, it has been renamed Lysinema pentapetalum. The species are very similar, but rarely interbreed. Lysinema ciliatum flowers have a sweet smell, less flowers per group, lighter coloured bracts and are mainly further south. Further information.

​Genus Andersonia (unchanged)
There is only species, Andersonia caerula - Foxtails and a few priority 2 species in Narrogin district. The stunning Foxtail flower has long pink sepals designed to attract birds and delicate pale blue petal tubes with a narrow entrance, which is packed with stamens and the pistil to keep unwanted insects out. Pollinators need a firm beak or tongue to get through to the nectar. Honeyeaters are listed as major pollinators, but bees were active when I visited them at Ylliminning Nature Reserve.

Ex-genus Astroloma (now Styphelia)
This hardy group has sepals shorter than, and which clasp a pollen tube with short hairy-interior lobes. I was surprised to learn that all local species are pollinated by Western Spinebills and honeyeaters. On reflection, it made sense because most flowers are red-orange and have tight narrow petal-tube entrances. All species have fleshy berries, which are dispersed by birds and bobtail skinks. Emus were particularly common eaters of flowers and berries. Alas no longer in our widely dispersed reserves. As many Astrolomas are fire-sensitive, a lack of emus to disperse seed could threaten their long term survival. They are generally very tough and long-lived, and have evolved to live in dry places.
​There are five species in Foxes Lair.

​Ex-genus Leucopogon (now Styphelia)
There are many species in Narrogin district reserves, which have similar looking flowers - small whitish flowers with long petal-tube lobes, usually with an abundance of fluffy hairs on upper side of the lobes. They are exquisite close-up. The short open petal tube provides nectar access for a range of flying insects (flies wasps butterflies and moths, gnats, birds), but bees are the main pollinators.
​There are three species in Foxes Lair.
