Heliophilodae D.A.German, Hendriks, M.Koch, F.Lens, Lysak, C.D.Bailey, Mumm. & Al-Shehbaz, supertrib. nov.

Type.

Heliophila L.

Description.

Trichomes absent or simple, rarely branched; multicellular glands absent. Leaves mainly not or slightly divided, rarely much divided to compound, usually not auriculate at base. Base numbers are various due to post-polyploid diploidization - 12 tribes have originated through whole-genome duplications (data lacking for Hillielleae ).

Distribution.

Well-represented in both Hemispheres ; Eurasia (mainly SW Asia & S Europe), N, Tropical & S Africa, C & S America, New Zealand.

Tribes.

Anastaticeae DC., Asteae Al-Shehbaz, Warwick, Mumm. & M.A. Koch [incl. Scoliaxoneae Al-Shehbaz & Warwick], Biscutelleae Dumort., Chamireae Sond., Cremolobeae R. Br., Eudemeae Al-Shehbaz, Warwick, Mumm. & M.A. Koch, Heliophileae DC., Hillielleae H.L. Chen, T. Deng, J.P. Yue, Al-Shehbaz & H. Sun, Iberideae Webb & Berthel., Megacarpaeeae Kamelin ex D.A.German, Notothlaspideae Al-Shehbaz, Warwick, Mumm. & M.A. Koch, Schizopetaleae R. Br. ex Barnéoud, Subularieae DC.

Notes.

This group corresponds to evolutionary lineage V of Nikolov et al. (2019) and Hendriks et al. (2022). Anastaticeae , Biscutelleae , Hillielleae , Iberideae , and Megacarpaeeae are tentatively assigned to Heliophilodae due to their partially resolved phylogenetic position (grouping with others only in nuclear-based trees; see Hendriks et al. (2022) for details and discussion). Eventually, these five tribes may be recognized as a separate supertribe, e.g., Anastaticodae , based on the most speciose tribe among them. In the latter case, Heliophilodae would become unique among supertribes being almost completely restricted to the Southern Hemisphere.
