Flannel Flowers have flourished in the National Science Week fight for Australia's favorite flower.

We have a few species here in Western Australia including Actinotus humilis, shown here flowering on sandplain near Perenjori following fire.

It’s time to cast your vote for Australia’s most amazing flower from the unsung understorey.

The ABC has selected 10 finalists, all with a superpower (only 10 we cry?!). Perhaps you’ve got some thoughts on what’s missing from this list, or which bloom should reign supreme.

Our triggerplant expert Juliet Wege reckons there's only one choice. She may well be onto something…

Move over waratahs and banksias! These 10 flowers from the unsung understorey are not just pretty faces, they have surprising tricks up their sleeves.

As we get closer to Djilba and spring, it’s the perfect time to get down and take a closer look at slime moulds. The Red Raspberry Slime Mould (Tubifera ferruginosa) is one of many species you may find out and about on rotting wood, bark or amongst the leaf litter. It is an easily recognised species because of its relatively large and brightly coloured bleb stage of development, hence its common name. The bleb stage is the transition between the feeding plasmodium (slime) and the mature pseudoaethalium filled with mature spores. As the bleb matures, it turns a brownish colour and is usually quite difficult to find as it will be camouflaged against the substrate. These slime moulds occur as a single pseudoaethalium up to a relatively large grouping, each one pillow-shaped, 5–20 mm across, with a somewhat rounded and intricate top surface. A pseudoaethalium is a compound fruiting of many individuals that fuse to look like one individual, which the mature top surface reveals.

This species occurs on rotting wood or thick bark, often on Banksia species, in seasonally wet periods in the south-west and Kimberley regions. Recent studies suggest this species may not occur in Australia and work is ongoing to determine which species we may have here.

Some cutting-edge research has revealed that the Threatened species Adenanthos eryei — first collected in 1973 only to never be seen again — is a hybrid between A. forrestii and A. cuneatus.

In the absence of living plants, genomic DNA was sequenced from a duplicate of the original collection housed at the Australian National Herbarium and compared to DNA from related species to reveal its taxonomic status. It will soon be known as A. × eyrei to show that it is a hybrid and will likely be de-prioritised for conservation efforts.

This fabulous collaborative effort shows the value of herbarium collections and the secrets they hold long after they are pressed and dried. Congratulations to the project team – Ben Anderson, Rachel Binks and Katherine Taylor (DBCA Biodiversity and Conservation Science), Emma Adams (DBCA Esperance District) and Brendan Lepschi (Australian National Herbarium, CSIRO).

Malvaceae mavens Carol Wilkins and Kelly Shepherd are bringing over 60 years of combined specialist knowledge to a three-year project on tribe Lasiopetaleae. With support from the National Taxonomy Research Grant Program, the duo will create online profiles of more than 200 species for the Flora of Australia, including some taxonomic novelties and plenty of rarities.

The first year of the project has seen them visit the Queensland Herbarium and Australian National Herbarium where they verified the identity of thousands of collections while carefully measuring plant features to refine taxonomic descriptions and associated information to ensure the most up-to-date and accurate information will be mobilised.

The project team also includes Katherine Downes and Juliet Wege, who are providing editorial and imaging assistance, including capturing images of herbarium specimens and vouchered field photographs.

Solanum diversiflorum
To celebrate NAIDOC week (5–12 July 2026), this month we feature the culturally significant bush tucker plant on Martu Country, Wamurla or Bush Tomato (Solanum diversiflorum).

Wamurla is a shrub growing to 15–50 cm high, forming rounded intricate bushes with deeply lobed leaves and fearsome prickles to 1 cm long on stems, leaves, peduncles and calyces. The inflorescence consists of one bisexual flower below a cyme of up to 20 male flowers. The flowers are mauve/purple, c. 2 cm in diameter, with 5 segments to the corolla and 5 yellow stamens.

The significance of Wamurla as a bush tucker plant is demonstrated by the Martu Traditional Owner practices of dispersing wild Solanum seed and traditional burning, as Wamurla come up especially well after fire.

Occurs from north-western W.A. north of the Tropic to the Kimberley, extending east to the Tanami Desert in N.T. usually on red sandy plains, often with gravelly capping, or on low stony hills, dominated by Triodia and Acacia.

Barely a day goes by without an Australian botanist accessing information in the Biodiversity Heritage Library, an invaluable treasure trove of botanic texts including an archive of journals from Australian herbaria (https://www.biodiversitylibrary.org/collection/AustralianHerbariaJournals).

https://www.theguardian.com/environment/2026/jun/18/natural-world-digital-biodiversity-heritage-library-scientific-knowledge-free-access-aoe?CMP=share_btn_url

The Biodiversity Heritage Library is an invaluable online archive of historic texts on species living and lost supplied by the world’s leading museums and universities. Now its future is in doubt

What better way to warm up the start of winter than by highlighting a stunning tropical species! Here we show off Osbeckia australiana, a small, hairy, perennial shrub that grows to 2 m tall and features terminal inflorescences adorned by 1– 5 gorgeous mauve flowers. Osbeckia australiana is the only member of the genus in WA (there are 50 worldwide) and is included in the speciose Melastomataceae family, which is also poorly represented in WA with only three genera and three species. The large flowers have 10 prominent bright yellow anthers positioned to one side above the stigma, a feature seen in many of the species in this family. While little is known regarding pollination for this species, others in the family are largely (but not always) buzz pollinated by bees, where the wing movement helps release the pollen through a pore-like opening at the apex of the anther. This allows for pollination to occur and their hairy fruit to form. These fruits are dry globose capsules when mature and release numerous, very small seeds.

Occurs on damp or swampy soils near creeks from Vansittart Bay south to Mt Leake near the Adcock River, on offshore islands and extending to the western half of Arnhem Land in the N.T.

𝗧𝗵𝗮𝗻𝗸 𝘆𝗼𝘂 𝗪𝗔 𝗛𝗲𝗿𝗯𝗮𝗿𝗶𝘂𝗺 𝘃𝗼𝗹𝘂𝗻𝘁𝗲𝗲𝗿𝘀! 🌱

The Western Australian Herbarium at the Department of Biodiversity, Conservation and Attractions hosted a morning tea last week to thank the 74 volunteers and research associates that help this important facility operate, generously donating 6241 hours of their time over the past year.

Volunteers come from all walks of life and help with preparing specimens for storage in the Herbarium’s climate-controlled vaults (known as ‘mounting’) and digitising existing specimens to make them more widely accessible.

Thank you to all our volunteers 🤝
