Common name: Honey Flower
The common name "honey flower" is derived from the flowers which produce a clear nectar in large quantities
Also, mountain devil from the fruit's resemblance to a devil's head - the horned woody follicles, were used to make small devil-figures
Conservation status: Least concern
Not considered to be at risk in the wild
Etymology:
The genus was named in 1798 by Sir James Edward Smith in honour of English botanist Aylmer Bourke Lambert
The specific name formosa is the Latin adjective for 'handsome' with reference to the flowers
Flowers:
The pink to red flowerheads that generally appear in spring and summer
Flowers are seen at any time of the year, but more often over spring and summer (September to January)
Their bases are covered by greenish and reddish bracts
The inflorescences are almost always made up of seven smaller individual flowers (less than 1% of flowerheads, which have 6 - 8 flowers), known as florets, and can be shades of red or pink in colour
The tubular perianths are 4.5 cm long, with the styles protruding another 1–1.5 cm beyond
The flowers hold profuse amounts of nectar and are pollinated by honeyeaters
Fruit:
Flowering is followed by the development of woody fruit which measure 2–3 by 1–2 cm
They have two 1–1.5 cm sharp horny protuberances, and a 0.5 cm 'beak', initially pale green in colour before fading to a grey-brown
These woody follicles each have two flat, winged seeds that are retained until burnt by fire
Leaves:
The stiff narrow leaves are arranged in whorls of 3, or sometimes up to 4 to 6, on the stems
They are linear to narrow-oblanceolate in shape
Measuring anywhere from 1 to 8 cm in length and 0.2–0.7 cm wide, they have a pointed tip or apex
Stem & branches:
The new growth is covered with a fine brownish hair
Roots:
Habit:
A spreading shrub to 2 m tall, with one or more stems arising from a woody base known as a lignotuber (from which it regrows after bushfire)
Habitat:
In the Sydney Basin, it is found from altitudes of zero to 1100 m above sea level, and in areas of rainfall from 800 to 1400 mm annually
It generally grows in heathland, mallee shrubland and dry sclerophyll forest, predominantly found on sandy or rocky soils
Associated heathland species include:
dwarf apple (Angophora hispida), paperbark teatree (Leptospermum trinervium), rusty banksia (Banksia oblongifolia) and heath banksia (Banksia ericifolia), while woodland trees include silvertop ash (Eucalyptus sieberi), smooth-barked apple (Angophora costata), narrow-leaved apple (A. bakeri), red bloodwood (Corymbia gummifera), yellow bloodwood (C. eximia), scribbly gum (Eucalyptus sclerophylla), and Sydney peppermint (E. piperita)
One heathland community located between Lake Munmorah and Redhead grows at least partly on clayey soils
Here, L. formosa grows under mallee forms of brown stringybark (Eucalyptus capitellata) and broad-leaved white mahogany (E. umbra) and alongside shrubby forms of prickly-leaved paperbark (Melaleuca nodosa), dagger hakea (Hakea teretifolia), scrub she-oak (Allocasuarina distyla), rusty banksia and swathes of kangaroo grass (Themeda triandra)
Distribution:
Endemic to NSW
Found on or east of the Great Dividing Range from the vicinity of Braidwood north to Port Stephens, as well as some parts of northern NSW around Grafton and between Red Rock and Yamba

Taxonomy
Specimens of Lambertia formosa were collected by botanists Joseph Banks and Daniel Solander during Lieutenant James Cook's landing at Botany Bay between April and May in 1770
These are thought to have been obtained from vegetation currently known as the Eastern Suburbs Banksia Scrub that occurs in sandy areas near present-day La Perouse
The shrub was first described in 1798 by English botanist James Edward Smith who concurrently erected the new genus Lambertia, the name honouring English botanist Aylmer Bourke Lambert
French botanist Michel Gandoger described specimens collected at Hornsby and Port Jackson as Lambertia proxima, and material sent to him by plant collector Charles Walter as L. barbata in 1919; these turned out to be L. formosa
Gandoger described 212 taxa of Australian plants, almost all of which turned out to be species already described
One of ten species of the genus Lambertia within the family Proteaceae, Lambertia formosa is the only one found in eastern Australia as the others are all restricted to southwest Western Australia
No subspecies are recognised, although plants in the southern part of its range from Bargo River to Braidwood have longer leaves
Ecology
Plants can live for over 60 years
Bushfire
Lambertia formosa regenerates after bushfire by resprouting from its woody lignotuber, but is also serotinous in that it has a seed bank held in its canopy to be released after fire
The number of flowers produced by plants growing back from fire peaks two or three years afterwards
A field study in Brisbane Water National Park north of Sydney found that plants that had experienced two short (less than seven-year) intervals between bushfires had reduced reproductive output as measured by lower numbers of follicles, compared with plants in areas which had had no or one short inter-fire interval
Bird pollinators
The red/pink colour, length of the tube and properties of the nectar indicate that the flower is pollinated by honeyeaters, which perch as they consume the nectar
Species observed foraging include the white-eared honeyeater (Lichenostomus leucotis), white-cheeked honeyeater (Phylidonyris niger), New Holland honeyeater (Phylidonyris novaehollandiae), noisy miner (Manorina melanocephala), little wattlebird (Acanthochaera chrysoptera), eastern spinebill (Acanthorhynchus tenuirostris), and yellow-faced honeyeater (Lichenostomus chrysops)
Honeyeaters are found in greater numbers in the vicinity of plants with more flowers
Insect pollinators
Caterpillars of the Australian cup moth species Xylorycta strigata eat the leaves and make burrows in the wood
The plant also hosts caterpillars of the cup moth species Mecytha fasciata
Cultivation
Cultivation in England
Lambertia formosa was one of the earliest introductions of Australian plant species to cultivation in England
In 1788, seed was sent from Botany Bay to the Lee and Kennedy's nursery in Hammersmith, west London
Two varieties were raised, one designated as "var. longifolia"
The first recorded flowering was a plant grown by J. Robertson of Stockwell in July 1798
Andrews wrote the following year that it is "without difficulty raised by cuttings, and thrives in peat earth"
Knight reported in 1809 that it required more heat and close care than other Australian plants and hence would never be widely cultivated in England
Propogation
Lambertia formosa is readily grown in cultivation given a sunny position and fair drainage, though it tolerates a range of soils and some shade
The plant responds well to pruning
Seeds germinate within 25 to 60 days of sowing, and firm young growth makes the best cutting material for propagation
Fertilisers generally are not needed, but slow release low-phosphorus fertilisers are tolerated
The species is frost-hardy and grows in temperate to subtropical climates.
Although L. formosa is uncommon in cultivation, it is straightforward to grow in soils with good drainage and a partly shaded to sunny aspect
It is readily propagated by seed
Resistant to Phytophthora
Unlike all other members of the genus Lambertia, L. formosa is greatly resistant to the soil pathogen Phytophthora cinnamomi
Hence it has potential as a rootstock for grafting Lambertia species of Western Australian origin, all of which are highly sensitive to root rot
Its flowers attract birds, especially important as this can provide a source of food year-round
Uses and cultural references
Nourishment
The flowers produces a clear nectar in large quantities; this was a source of nourishment for Australian Aboriginal Peoples and, following European colonisation, explorers, escaped convicts and children were recorded sucking the flowers
Explorer Ludwig Leichhardt wrote that "often when I've been tired and thirsty, I've bitten off the base of a tuft of Lambertia formosa flowers to suck the delightfully sweet honey out of them"
Headaches and nausea have been reported from ingesting large quantities of the fluid, though it is not known to contain a toxic substance
Illustrations
The species was the subject of an illustration by Sydney Parkinson, artist on HM Bark Endeavour's voyage to the Pacific from 1769 to 1771
A colour botanical engraving based on Parkinson's work is part of Banks' Florilegium
First Fleet midshipman and artist George Raper depicted the species in two works: an untitled watercolour study (c. 1788) and Bird Of Point Jackson (1789)
Writer and illustrator George Collingridge incorporated the flower in several of his designs and unsuccessfully championed it as the floral emblem of Australia
Hand-crafted figures
Hand-crafted figures have been made using the mature woody fruit for a head, together with pipe cleaners, wool and fabric scraps
Known as "mountain devils", these were sold as tourist souvenirs in the Blue Mountains
