TaxonomyThe phylogenetic study of Klak shows a close relationship of the Drosanthemum, Dicrocaulon, Gibbaeum, Delosperma, Mitrophyllum, Jacobsenia and Conophytum clades. Together they are paraphyletic.
Plant theory 2Delospermoideae is so far a paraphyletic clade and placed in
Subphase 6. Many cases have confirmed the
Phase 6 of remedies from several subclasses of
Delospermoideae.
DelospermoideaeDrosanthemeae: Drosanthemum
Dicrocauleae: Dicrocaulon, Diplosoma, Monilaria, Oophytum
Gibbeae: Gibbaeum, Glottiphyllum, Malephora
Delospermeae: Corpuscularia, Delosperma, Frithia, Mestoklema, Trichodiadema
Mitrophylleae: Meyerophytum, Mitrophyllum
Jacobsenieae: Drosanthemum, Jacobsenia
Conophyteae: Cheiridopsis, Conophytum, Enarganthe, Jensenobotrya, Namaquanthus, Octopoma, Polymita, Ruschianthus, Schlechteranthus
Delospermoideae according to HartmannDelosperma: Corpuscularia (8), Delosperma (c. 158), Drosanthemum (120), Gibbaeum (incl. Muiria) (17), Malephora (8), Mestoklema (6), Trichodiadema (34), Oscularia (23)
Mitrophyllum: Dicrocaulon (7), Diplosoma (2), Disphyma (4), Glottiphyllum (16), Jacobsenia (3), Meyerophytum (2), Mitrophyllum (6), Monilaria (5), Oophytum (2)
BotanyLeaves: epidermis with bladder cells; axis with cortical bundles.
Flowers: gynoecium half-inferior or inferior, with a central placenta; shell-shaped nectaries separate; staminodial petals mostly fused with the stamens forming a tube below.
Fruit: hygrochastic capsule with expanding keels reaching from the columella to the tip of the valve; very rarely a nut.
Chromosome number: x = 9.
