03A01863FFEDFF9A7BFFFD54F05F46A6.taxon	description	Description. The holotype specimen is 42 mm long and 20 mm wide, preserved as a compression with some coalified residue and an impression (Fig. 2 a). The plant tissues are embedded in yellowish volcanic tuff (Fig. 2 a – c). When the coalified residue falls off, an exquisite morphological impression is left on the fine sediment matrix (Figs 2 d – i & 3 a – g). The preserved part of the fossil includes a leafy branch that is physically connected to a fruit and a flower bud (Fig. 2 a). The branch is elongated, approximately 21 mm long and 2.6 mm wide, with longitudinal fine striations on its surface and at least five nodes, tapering distally (Figs 2 a, d, h & 3 b, d, e). The nodes are marked by several transversal wrinkles (Figs 2 h & 3 b). The lengths of the internodes increase from 2.9 mm at the proximal to 5.1 mm at the distal (Fig. 2 a, h). Leaves with decurrent bases are helically arranged along the branch, more concentrated to the distal portion of each internode (Figs 2 h & 3 d). All of the leaves have been abscised and only have their scars left on the branch (Figs 2 a, h & 3 d). The leaf scars are 0.4 – 0.6 mm wide and 0.23 mm thick, with terminal abscission zones (Fig. 3 b, d & e). Close to the terminal of the branch, fruit pedicel scars are subtended by bracts (Fig. 3 a – c). The fruit pedicel with longitudinal fine striations is rounded in cross-view, branching into a pair (Figs 2 a – c, i, j & 3 h – i). The fruits are inserted subapically (Figs 2 a, b & 3 a). The flower bud (only one visible in full) is in pairs, on a straight pedicel approximately 4.6 mm long and 1 mm wide, oval in shape, approximately 3.8 mm long and 3.3 mm wide (Fig. 2 a, b, e – g, i, j). Several layers of upper tepals enwrap the central part (Figs 2 e – g, 3 g – i, 4 & 5 a). Micro-CT sections indicate that the tepals surround the bud centre (gynoecium?) (Fig. 3 h, i). Uppertepals vary from 1.8 to 3.8 mm in length and from 1.5 to 2.6 mm in width (Figs 2 e – g, 3 g & 5 a), distinguishing from each other by differently orientated sculpture (Figs 2 e – g, 3 g, 4 & 5 a). The fruit is approximately 11.5 mm long and 7.7 mm wide, on a pedicel 22 mm long and only 0.65 mm wide, subtended by four (only three visible in the fossil) foliar parts approximately 2.4 mmlongand 1.4 mm wide, with an apical invagination approximately 0.5 mm deep (Figs 2 a, c, k, l & 3 j). Only the mesocarp and endocarp of the fruits are visible, while the exocarp (epidermis) is too thin to see (Figs 2 a, c, k & 5 b). The mesocarp is approximately 0.34 – 1.1 mm thick, much thinner near the fruit tip (Figs 2 a, c, k & 5 b). The endocarp is approximately 9 mm long and 6 mm wide, with a pointed tip (Figs 2 a, c & 5 b). Depository.

03A01863FFEDFF9A7BFFFD54F05F46A6.taxon	discussion	Remarks. Only one flower bud and one fruit are preserved in entirety in this fossil. However, there is one extra slender pedicel that is identical to that of the preserved fruit (Fig. 2 a, b, i), and there seems to be another pedicel of a flower bud embedded in the sediments (Fig. 2 i, j). Considering the morphology of the fruit pedicel, we assume that it is another fruit, which, unfortunately, is not visible in this specimen. Furthermore, several fruit pedicel scars (Fig. 3 a – c) strongly imply the existence of fallen fruits in Florigerminis. Therefore, we assume that this fossil originally bore two fruits and two flower buds.	en	Cui, Da-Fang, Hou, Yemao, Yin, Pengfei, Wang, Xin (2022): A Jurassic flower bud from China.
