Paul Sheringham thought he'd collected a familiar plant when he gathered samples north of Grafton in northeastern New South Wales, but botanists at the University of New England saw something else entirely—a species that had hidden in plain sight for over a century. What Sheringham, a rare-plant expert with the Department of Climate Change, Energy, the Environment and Water, had brought back was actually Phebalium banyabba, a previously unknown shrub with flowers of stunning pink and rusty hues, now formally described in the journal Telopea and ending generations of scientific misidentification.
The discovery matters because it reveals how much biodiversity remains overlooked even in well-studied regions, and because Phebalium banyabba is already critically rare. With fewer than 1,000 individual plants surviving in the wild across just two locations—466 in one site, 502 in another—the species faces multiple threats that demand immediate conservation attention. Botanists have identified too-frequent fire, drought, cattle grazing, and the plant's dependence on seed regeneration rather than resprouting as the primary pressures threatening its survival.
At the N.C.W. Beadle Herbarium, Emeritus Professor Jeremy Bruhl and Dr. Ian Telford led the formal description of the species, which grows as a compact shrub less than two meters tall and blooms with characteristic pink and rusty flowers from late winter through spring. The name Phebalium banyabba honors the Bandjalang First Nations people, whose language names the region where the species is endemic. Molecular analysis by then Ph.D. student Dr. Sangay Dema confirmed what the botanists observed in the field: the plant's distinctive morphological features, including densely hairy calyces with unique dendroidal hairs, larger calyx lobes, and seeds larger than those of related species.
What happens next reveals how modern botany bridges conservation and horticulture. Emeritus Professor Bruhl and horticultural staff at the Australian National Botanic Gardens have already begun propagating Phebalium banyabba to understand its cultivation needs, and specimens have been incorporated into the ANBG's living collection. The strategy is thoughtful and practical: by introducing the species to the horticultural trade through legitimate channels, botanists aim to reduce pressure from illegal wild collection—a threat that confronts many rare plants. The formal publication of the species also facilitates its listing as a Threatened Species under NSW legislation, opening pathways for government protection programs like Saving our Species.
"Phebalium banyabba forms a lovely shrub less than two meters tall and is covered with stunning pink and rusty flowers in late winter through spring," Emeritus Professor Bruhl said, capturing both the botanical elegance and the promise of the discovery. His words hint at what conservation success could look like: a once-anonymous shrub now recognized, protected, and cultivated, its beauty no longer hidden but celebrated. Across the herbarium, a comprehensive revision of the broader Phebalium nottii complex continues, suggesting that more discoveries may yet emerge from careful botanical work and the willingness to look twice at what we thought we already knew.
