Proposed possible evolutionary roadmap related to Combina gen. nov., from a conifer (Drepanolepis) to extant Illicium. The scale/funiculus is in dark gray, the ovule is in white, and the bract is in black. (a–c) Adaxial, lateral, and cross view of a lateral unit in Drepanolepis. (d–f) Adaxial, lateral, and cross view of a lateral unit in Elatides23. Note the wings of the bract curving adaxially. (g–i) Adaxial, lateral, and cross view of a lateral unit in Combina gen. nov. Note the axillary ovule is almost fully enclosed except along the ventral suture (gap). (j–l) Adaxial, lateral, and cross view of a carpel in extant Illicium (Illiciaceae).
