General view and details of the holotype of Combina gen. nov. specimen number MPZ2009-425. (a) The organ including multiple helically arranged lateral units. Scale bar = 10 mm. (b) Detailed view of the lateral unit 3 in (a). Scale bar = 1 mm. (c) The same as in (b), under SEM. The ovule is colored artificially. Scale bar = 1 mm. (d) SEM view of the lateral unit 1 in (a), showing the adaxial suture (arrow) of the bract. The ovule base is colored artificially. Scale bar = 1 mm. (e) View of the lateral unit 1 in (a), showing the adaxial suture (arrow) of the bract. Scale bar = 1 mm. (f) Detailed view of the basal portion of the ovule (artificially colored) that is eclipsed by the adaxial part of the bract, under SEM, enlarged from (d). Scale bar = 0.5 mm. (g) View of the lateral unit 4 in (a), showing the ovule “sandwiched” adaxially and abaxially by its bract. Scale bar = 2 mm. (h) Detailed view of the ovule (arrows), enlarged from (g). Scale bar = 1 mm. (i) Detailed view of the ovule base, enlarged from (b), showing its physical connection (funiculus, between white arrows) to the organ axis (oa). Note the asymmetrical connection (black arrow) between the funiculus and the ovule. Refer to Figure 3a. Scale bar = 1 mm. (j) Detailed view of the lateral unit 2 in (a), showing the asymmetrical connection (arrow) between the ovule and its funiculus. Refer to Figure 3b. Scale bar = 1 mm.
