Morphology Reproductive morphology Flowers Androecium Stamens Anthers
Anther bases produced into oblong fimbriate or ciliolate tails.
Morphology Reproductive morphology Flowers Gynoecium Style
Styles deeply 2-fid, branch apices shortly conical with a sub-distal fringe of hairs.
Morphology Reproductive morphology Fruits
Achenes doliform-cylindric, c. 5-angled or ribbed, usually with a ± swollen or lobed cartilaginous carpopodium at the base, minutely puberulous or glabrous; pappus of 4–5 caducous barbellate setae.
Morphology General Habit
Annual herbs, or suffrutices with annual stems from woody rootstocks.
Morphology General Indumentum
Vegetative indumentum of appressed fine ± matted hairs usually intermixed with large patent many-celled uniseriate hairs each bearing a fine filamentous terminal cell.
Morphology Stem
Stems 1-several, simple or branching near the apex, araneose-lanate to coarsely pubescent Leaves alternate, semi-amplexicaul, usually discolorous, indumentum as for stem but denser on the lower surface, sometimes ± scabrid.
Morphology Reproductive morphology Inflorescences Capitulum
Capitula homogamous and discoid or heterogamous with inner florets regular and outer florets bilabiate-radiate, 1-many, solitary and terminal on stem and branches.
Morphology Reproductive morphology Inflorescences Bracts Involucre
Involucres ± broadly campanulate, ± truncate at the base.
Morphology Reproductive morphology Inflorescences Bracts Phyllaries
Phyllaries many-seriate, appressed imbricate, the innermost grading into the paleae of the common receptacle, fimbriate-denticulate on the margins or sometimes denticulate about the apex only; apices sometimes long caudate, or in inner phyllaries expanded ovate and appendage-like.
Morphology Reproductive morphology Flowers Receptacle
Receptacle paleate.
Morphology Reproductive morphology Flowers Florets
Ray-florets when present functionally male, with deep-red bilabiate-radiate corollas, outer lip (ray) large 3-fid, inner lip shorter consisting of 2 linear lobes. Disk-florets deep-red or creamy-white, occasionally orange-tinged, hermaphrodite and actinomorphic, abruptly dilated into a deeply lobed limb, lobes erect linear.

Morphology General Habit
Perennial or rarely annual herbs with leafy stems, or scapose and the leaves all basal
Morphology Leaves
Leaves alternate, petiolate or sessile with a petioloid base, pinnately veined, mostly serrulate
Morphology Reproductive morphology Inflorescences Capitulum
Capitula solitary, few, terminal on the inflorescence branches, sometimes precocious, at first erect, homogamous and discoid or apparently radiate with unequally bilabiate outer florets, these sometimes female-sterile and the capitula heterogamous; phyllaries few-seriate, closely imbricate, the outer laciniate-dentate, the inner entire except at the apices and passing into the receptacle-scales; receptacle mamillate, scaly
Morphology Reproductive morphology Flowers Florets
Florets all hermaphrodite, all regular or the outer unequally bilabiate and sometimes functionally male; corolla narrowly tubular below, in bilabiate florets with broad deeply 3-toothed or 3-lobed ray-like outer lip and shorter inner lip narrowly 2-lobed to the base, in regular florets narrow in lower half, dilated, campanulate and deeply 5-lobed above; anthers strongly tailed, tails conspicuous, fringed; style branches short to long, obtuse, with a subapical dorsal fringe of hairs
Morphology Reproductive morphology Fruits
Achenes all similar or those of the ray florets abortive, the fertile achenes inflated, cylindrical, 5-angular, obtusely ribbed on the angles; pappus of a few very caducous flattened barbellate bristles, whitish or tawny.

Morphology Reproductive morphology Inflorescences Capitulum
Capitula in lax corymbiform cymes, homogamous, discoid; phyllaries imbricate in 4–5 series, progressively longer inwards, entire, obtuse; receptacle glabrous, mamillate, scaly
Morphology Reproductive morphology Flowers Florets
Florets all hermaphrodite; corolla narrowly tubular below, suddenly expanded just above the middle into a campanulate-urceolate deeply 5-lobed upper part; anthers strongly tailed, tails conspicuous, fringed; style branches obtuse, with a subapical dorsal fringe of hairs
Morphology Reproductive morphology Fruits
Achenes inflated, cylindrical, 5-angled, bluntly ribbed on the angles; pappus absent.
