Doryanthes excelsa (Greek: δόρυ, dory, “spear” + ἄνθος, anthos, “flower”; Latin:
excelsus, “tall, high”) is commonly known as flame lily, giant lily, Gymea lily,
Illawarra lily or spear lily. In Eora (ee, "yes" + ora, "here, this place"), the dialect of
the indigenous Australian inhabitants of the area of Sydney, gymea means "giant
Australia's Flaming Red Spires: Gymea Lily (Doryanthes excelsa)
Native only in the area of Sydney, wild Gymea lilies reach heights of 16 feet (5 meters). Standing tall with fiery flowers, these colorful Aussie icons resemble flaming spires.

Doryanthes excelsa occurs natively in eastern coastal areas in the vicinity of Sydney (33° 51′ 35.9″ South latitude, 151° 12′ 40″ East longitude) in the southeastern state of New South Wales. Doryanthes excelsa ranges from the seaside city of Wollongong (34° 25′ 59″ South latitude, 150° 52′ 59″ East longitude), about 50 miles (80 kilometers) south of Sydney, to the bucolic town of Karuah (32° 39′ 22.2″ South latitude,151° 57′ 54″ East longitude), about 125 miles (200 kilometers) north of Sydney.

Three isolated populations of Doryanthes excelsa occur natively near the small town of Glenreagh (30° 3′ 0″ South latitude, 152° 59′ 0″ East longitude), about 280 miles (450 kilometers) north of Sydney, and near the small seaside town of Corindi (30° 1′ 37.2″ South latitude,153° 11′ 45.6″ East longitude), about 354 miles (573 kilometers) north of Sydney.
A hardy plant willing to tolerate widely divergent ecosystems, Doryanthes excelsa has expanded its range, adapting to city life in:
- Adelaide (34° 55′ 44.4″ South latitude, 138° 36′ 3.6″ East longitude) on the southeast coast of the southeastern state of South Australia;
- Brisbane (27° 28′ 4″ South latitude, 153° 1′ 40″ East longitude) on the east coast of the northeastern state of Queensland;
- Melbourne ( 37° 48′ 49″ South latitude, 144° 57′ 47″ East longitude) on the south coast of the southeastern state of Victoria; and
- Perth (31° 57′ 8″ South latitude, 115° 51′ 32″ East longitude) on the southwest coast of the western state of Western Australia.

Habitat: Urban and rural
Doryanthes excelsa thrives in the dry, open forest shrubland ecosystem of sclerophyll (Greek: σκληρός, scleros, “hard” + φύλλον, phyllon, “leaf”) communities, that is, woody plants with hard, leathery leaves, that characterize the eastern third of New South Wales, radiating from the coast inwards. Doryanthes excelsa is easily found in sandstone soil that is partly clay.
Doryanthes excelsa also grows in urban areas, such as gardens, parks and along roadsides.

Externals: What Doryanthes excelsa looks like
Gymea lily stands proud and tall, with its single stem reaching a height of up to 16.4 feet (5 meters).
Leaves are basal, meaning that they grow from the lowest part, or base, of the plant. Their dark to olive green surface is glabrous (Latin: glaber,“smooth, hairless, bald”), that is, smooth.
Leaves stretch in tussocks, like long swords, from 3.2 to 8.2 feet (1 to 2.5 meters) in length, with a width of 3.9 inches (10 centimeters). Shorter leaves, up to one foot (0.3 meters) in length, clamber sparsely up the stalk.

Trumpet-shaped flowers are bright red or pink red, with paler centers, although a rare whiteness may occur. Individual flowers, about 4 to 6 inches (10 to 16 centimeters) in length, form spectacular clusters with a diameter of up to two and one-third feet (0.6 meters). The flaming cluster dramatically rests on top of the solitary, lanky stem, which itself emerges proudly from the center of the base's spiky tussock of leaves.
Stamens (Latin: stamen, “thread of the warp”), which are a flower’s pollen-producing reproductive organs, normally comprise a filament (Latin: filum, “thread”), or stalk, topped by an anther (Greek: ἄνθος, anthos, “flower”). Filaments are twice the length of anthers, which measure measure one to one and one-half inches (27 to 38 millimeters) in length. The anthers of Doryanthes excelsa are green yellow.
Doryanthes excelsa produces a pod that matures to a red brown color. Elliptical to ovoid (Latin: ovum, "egg") in shape, seed pods measure about 2.7 to almost 4 inches (7 to 10 centimeters) in length.
Seeds are flat and brown with a length of about 0.6 to 0.9 inches (1.5 to 2.5 centimeters).
Gymea lily's other common names include flame lily, giant lily, Illawarra lily, and spear lily

Life cycle ~ Irregular inflorescence
The stalk spurts out from the leafy tussock during winter. Flowers blossom in spring and summer. Thereafter seed pods appear, splitting open in January or February.
Irregular inflorescence: Jumpstarting flowering with a blow torch or a pebble
A disappointment that frustrates admirers of Doryanthes excelsa is its proclivity towards unpredictable inflorescence, that is, flowering. Strategies exist for triggering inflorescence. In the wild, Doryanthes excelsa are stimulated to flower after bush fires, which stimulate the production of ethylene, its naturally occurring, ripening hormone.
According to Jeremy Smith, who cultivates Gymea lilies on his farm on the central coast of New South Wales, flowering may be induced by simulating bush fire conditions. Jeremy's effective simulator is a blow torch. Nevertheless, he cautions against home gardeners trying his method. Instead, a pebble, placed in the center of the plant, serves as an effective, far less dangerous, stimulant.

Ethnobotany: Household items and culinary delights with Doryanthes excelsa
Indigenous Australians cut down the tender stalks, at about 1.5 feet (0.5 meter) in height, for roasting.
Roots were also roasted and then used in a cake that was eaten cold.
Fibers in the leaves were used in making brushes and mats.

Synecology: Second-trophic level feeders
There are basically four to five trophic (Greek: τροφή, trophē, "food, feeding") levels in the food chain, encompassing primary producers, such as plants, in the first level, herbivores (Latin: herba, "small plant, herb" + vorare, "devour, swallow"), or plant eaters, in the second level, on up to apex predators, species at the top of their food chain.
Synecology (Greek: σύν, syn, “with” + oικoλoγία, ecologia, “house” + “study”) expresses the interrelationships an organism and other inhabitants of the ecosystem, identifying any persistent faunal and floral communities and any consistent geological environment.
In the second trophic level of these floral-faunal synecologists, nectar loving birds, such as honeyeaters (family Meliphagidae), rainbow lorikeets (Trichoglossus haematodus), and wattlebirds (genus Anthochaera) are attracted to Doryanthes excelsa nectar.

Flaming red spires: Australia’s iconic coastal sentinels
A bed of Doryanthes excelsa resembles Olympic torches held high and is equally stunning. The lofty flaming scarlet splendor of Doryanthes excelsa in full flower mesmerizes with its intrinsically and uniquely Australian beauty. Native sentinels of the Sydney Basin along Australia's southeastern coast, Gymea lilies distinguish their landscape and extend warm welcomes with their iconic presence.

This article is dedicated to the memory of three dedicated naturalists, two of whom were superb illustrators and one of whom was an observant scientist:
- Ferdinand Bauer (January 20, 1760–March 17, 1826);
- Numa Morel;
- José Francisco Correia da Serra (June 5, 1751-September 11, 1823).
Their timeless contributions to understanding the intricacies of nature are forever appreciated.
