FOLIA exslipulata, sparsa, rarius opposita v. verticillata, plerumque coriacea persistentia, petiolata v. sessilia, simplicia integerrima v. saepius dentata v. varie laciniata, rarius pinnatipartita v. pinnata, nonnunquam in eadem stirpe diversiformia, apice dentibusve saepius pungenti-mucronatis, facie superiore saepius nitida, inferiore albo- v. ferrugineo-tomentosa rarius glabra, nervis pinnatis (rarius palmatis flabellatisve) subtus saepius eleganter reticulatis. FLORES in apice ramorum v. ramulorum capilati, spicati, umbellatofasciculali, racemosi v. paniculati, raro axillares subsolitarii ; capitulis spicisve sessilibus v. pedunculatis, imbricatim bracteatis, nonnunquam involucro generali (saepe insigni, colorato) suffultis ; rhachi v. receptaculo saepius incrassato cylindrico, conico v. sphaeroideo, alveolato, paleaceo v. villoso v. rarius nudo ; PEDICELLIS singulatim v. saepius geminatim ex axilla bracteae ortis v. nullis ; BRACTEIS persistentibus (interdum incrassatis induratisque) v. deciduis, nunc nullis ; FLORIBUS saepe speciosis albis, flavis v. rubris, rarissime caeruleis, saepius copiose melliferis, FRUCTIBUS seminibusque haud paucarum edulibus, nonnullarum causticoacribus rubefacientibus.
