Doryanthes excelsa, commonly known as gymea lily, is a flowering plant in the family, Doryanthaceae and is endemic to coastal areas of New South Wales near Sydney. It has sword-like leaves more than Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long and when it flowers, sends up a flower spike up to Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). high. The apex of the spike bears a large cluster of bright red flowers, each Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). across. Its common name is derived from the name given to the plant by the indigenous Eora people and the Sydney suburbs of Gymea and Gymea Bay are named after the lily.

Description

Gymea lilies have a rosette of large numbers of sword-shaped, strap like leaves Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long and Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). wide. The leaves are bright green, fibrous and glabrous.[1][2]

In winter the flower spike grows from the centre of the rosette until it is up to Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). high, bearing shorter leaves up to Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long. At the top of the spike, a head of flowers Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). in diameter develops, each flower being bright red, trumpet-shaped and about Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long. The head is surrounded by reddish-brown bracts, sometimes making it difficult to see the flowers from the ground. Flowering occurs in spring and is followed by oval-shaped reddish-brown capsules, Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long. In late summer, the capsule splits open and releases the seeds which are Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). long.[1][2]

Taxonomy and naming

Doryanthes excelsa was first formally described in 1802 by the Portuguese polymath, José Correia da Serra from the type specimen collected by George Bass "in mountainous parts of the colony of N.S.W.". The description was published in Transactions of the Linnean Society of London.[3][4] The genus name (Doryanthes) is derived from the Ancient Greek δόρυ (dóru) meaning a "spear", "lance" or "pole"[5] and ἄνθος (ánthos) meaning "a flower".[6] The specific epithet (excelsa) is a Latin word meaning "elevated" or "high".[7] Doryanthes excelsa and Doryanthes palmeri are the only two members of the family Doryanthaceae.[2]

"Doryanthes" has inspired the naming of the journal of history and heritage for Southern Sydney founded by Dharawal historian Les Bursill.[8]

Distribution and habitat

Doryanthes excelsa occurs in woodland and dry sclerophyll forest in coastal areas and adjacent mountains from Karuah to Mount Keira. It usually grows in soils derived from sandstone.[1]

Uses

Indigenous use

Aboriginal people roasted the young stems of gymea for eating. They also roasted the roots to make a kind of cake. Fibres from the leaves were used for making brushes and matting.[9][10]

Horticulture

Gymea lilies are hardy and adaptable plants often used in landscape gardening, not only in the Sydney region but also in other coastal areas such as Brisbane and Perth. Plants can be grown from seed but may not flower for up to eight years. Flowering can be encouraged by fire and by carefully placing a stone in the centre of the rosette.[2][11][12]
