Fig. 3 in A Jurassic flower bud from China

Fig. 3. SEM and micro-CT details of Florigerminis jurassica gen. et sp. nov. (a) Detailed view of the fruit/flower pedicels and leaf scar near the branch apex. Note the fruit pedicels (1 and 2), flower bud pedicel (3), two additional fruit pedicel scars (black arrows) and a leaf scar (white arrow). Labelled as in Figure 2b. The scale bar is 1 mm. (b) Details near a node, showing a leaf scar (white arrow), transversal wrinkles (black arrow) at the node and two possible fruit pedicel scars (outlined) subtended by scales. The scale bar is 0.2 mm. (c) Elliptical fruit pedicel scar enlarged from (a), subtended by a scale (arrows). The scale bar is 0.1 mm. (d) Branch with helically arranged decurrent leaf scars (arrows). The scale bar is 1 mm. (e) Decurrent leaf base (arrow) with abscission zone at the tip. The scale bar is 0.1 mm. (f) Subtending scale (below the line) and an axillary primordium (arrow), enlarged from the rectangle in (a). The scale bar is 0.1 mm. (g) Fragments of three overlapping tepals (1–3) with differently orientated surface textures. The scale bar is 0.1 mm. (h) Longitudinal micro-CT view of the flower bud with tepals (white arrow) surrounding gynoecium (?) (right arrow) in the centre. The fruit pedicel has obvious longitudinal fine striations (lower arrow). The scale bar is 1 mm. (i) Longitudinal micro-CT view of the flower bud with gynoecium (?) (arrow) in the centre and tips of the tepals at the top. The scale bar is 1 mm. (j) Longitudinal micro-CT view of the fruit with an apical invagination (arrow). The scale bar is 2 mm.
