    Compositae, H. Beentje, C. Jeffrey & D.J.N. Hind. Flora of Tropical East Africa. 2005

    Shrubby or herbaceous, often thistle-like, perennial
    Leaves alternate, sometimes decurrent and stems winged, occasionally forming a pseudo-rosette, margins of wings and leaves spiny
    Inflorescence solitary, racemose or subcorymbose; capitula eradiate or more usually radiate, showy; phyllaries multiseriate, usually spreading, the middle usually the longest, connate at base, ± stiff and variably spiny, spinescent, occasionally unarmed and spinescent; receptacle flat or shallowly domed, pitted, pits with scarious entire, dentate or erose walls sometimes produced into spines or scales
    Ray florets sterile or absent, when present in 1 series, spreading, yellow rarely white, entire with 5–10 veins and up to 5 teeth, ray narrowing into tube in lower part; staminodes usually present; disc florets bisexual, fertile, regular, tubular, enlarged above, normally 5-partite; anthers united, bases sagittate with obtuse to acuminate tails or auricled; styles forked (undivided in sterile florets) with narrow branches rounded at apex; all florets variably hyaline-multicellular-hairy
    Achenes set in pits, obovoid or more often turbinate, clearly or indistinctly ribbed, glabrous to long silky-hairy; pappus persistent, (exserted from pits), forming a usually sub-biseriate, rarely uni- or multi-seriate corona to the achene; pappus scales briefly connate at base, scarious, glabrous to hairy often dentate or erose.

    Compositae, G. V. Pope. Flora Zambesiaca 6:1. 1992

    Perennial herbs sometimes suffrutescent with annual stems from woody rootstocks, or subshrubs.
    Indumentum felted-tomentose on leaf under surfaces, araneose-tomentose elsewhere, consisting of many-celled uniseriate soft hairs with extremely long filiform white apical cells, their bases tending to become rigid and persistent.
    Leaves alternate, sometimes crowded on the lower stem, ± spiny, subentire to dentate, pinnatifid or pinnatisect with spinescent teeth, sometimes decurrent on the stem as spiny wings.
    Capitula heterogamous and radiate or homogamous and discoid, solitary or subcorymbosely arranged.
    Phyllaries several-seriate, connate at the base, always spiny with spines sometimes slender and bristle-like.
    Receptacle with deep alveolae which totally enclose the achenes leaving only the pappus exserted; the alveolae margins entire or irregularly toothed or setose.
    Ray-florets uniseriate, neuter, corollas yellow sometimes white, always with staminodes, achenes wanting. Disk-florets hermaphrodite numerous; corollas yellow, infundibuliform, deeply 5-lobed; anther bases sagittate; style branches linear; achenes ± turbinate, ribbed, villous pubescent or glabrous; pappus ± 2-seriate, of numerous short or long scales, sometimes partly connate.
