The Asteroideae is a major clade within the composite-flowered plants, a major characteristic of which is the presence of true ray florets in many species. Around 3000 species within the Asteroideae are placed in the tribe… Continue reading Asteroideae


Belongs within: Gnaphalieae. Gnaphalium is a genus of woolly herbs bearing clustered, heterogamous-discoid heads (Black & Robertson 1965). Characters (from Black & Robertson 1965): Tomentose or woolly herbs with alternate leaves; flowerheads small, usually clustered. Involucre ovoid, bracts in several rows, upper half scarious; receptacle naked; flowers all tubular, not exceeding involucre, outer ones female,… Continue reading Gnaphalium


Belongs within: Asteroideae.Contains: Raoulia, Anaphalis, Ozothamnus, Rhodanthe, Podolepis, Angianthus, Craspedia, Calocephalus, Gnaphalium, Cassinia, Helipterum, Helichrysum, Haastia. The Gnaphalieae are the tribe of composite-flowered plants including the everlastings and related taxa. Heads are mostly heterogamous in members of the subtribes Athrixinae and Gnaphaliinae but homogamous-discoid in Angianthinae. Members of the Athrixinae have fewer outer female flowers in the… Continue reading Gnaphalieae


Belongs within: Gnaphalieae. Helichrysum is a genus of everlastings widespread throughout the Old World. Heads have a naked receptacle with involucral bracts mostly scarious or with inner bracks petaloid and radiating (Black & Robertson 1965). Members of the section Xerochlaena are prostrate creepers with herbaceous or very softly woody stems (Allan 1961). Characters (from Black… Continue reading Helichrysum


Belongs within: Anthemideae.Contains: Artemisia section Tridentatae. Artemisia, including sagebrushes and wormwoods, is a mostly Northern Hemisphere genus of usually strong-smelling, wind-pollinated herbs and shrubs. Notable species include wormwood A. absinthium, used to make the spirit absinthe, and tarragon A. dracunculus, used as a culinary herb. Plants have discoid or disciform capitula with all florets hermaphroditic… Continue reading Artemisia


Belongs within: Asteroideae.Contains: Filago. The Inuleae is a group of composite-flowered plants in which the flower-heads are usually discoid, with outer ray-florets mostly absent or narrow and filiform. The receptacle bears chaffy scales in the subtribe Buphthalminae but is naked in Inula (Black & Robertson 1965). Elecampane Inula helenium, native to temperate Eurasia and naturalised… Continue reading Inuleae


Belongs within: Asteroideae.Contains: Helianthus, Verbesininae, Ambrosiinae. The Heliantheae are a group of composite-flowered plants distinguished by their scaled receptacles and (usually) stiff pappuses. Molecular studies indicate the presence of two major clades within the Heliantheae; interestingly, the morphologically similar genera Montanoa and Rojasianthe, sharing such characters as chromosome number, opposite phyllotaxy, accrescent pales, blackish disc… Continue reading Heliantheae


Belongs within: Asteroideae. The Plucheeae is a group of composite-flowered plants distinguished by their flowers with filiform style-branches. A number of species of the pantropical to warm temperate genus Pluchea are known as camphorweeds or sourbushes owing to their strong odour. Characters (from Black & Robertson 1965, as Plucheinae): Style-branches filiform, stigmatic on inner side,… Continue reading Plucheeae


Belongs within: Asteroideae. Senecio, the groundsels, is a large genus of composite-flowered plants found worldwide. Some species are significant as invasive pasture weeds, such as the toxic ragwort S. jacobaea. The fireweed S. madagascariensis, native to Africa, is potentially a serious pasture weed in Australia, but control has been complicated by taxonomic confusion between S.… Continue reading Senecio


Belongs within: Astereae. The Bellidinae includes the garden daisy Bellis perennis and its close relatives. Members of the Bellidinae are distinguished from other Astereae by having the pappus absent or much shorter than the achene (Black & Robertson 1965). The include the primarily Australasian genus Brachycome, members of which have predominately white ray-florets, a pappus… Continue reading Bellidinae
