The cover image shows a Miocene flower of Ayenia sect. Vahihara (Malvaceae) preserved in amber and its reconstruction based on X-ray tomography data. This provides evidence of lianas in a Miocene rainforest in southeast China, and reveals a morphological stasis in floral structure within a tropical liana lineage since at least ∽14.7 million years ago. [See Shi et al., pp. 1500–1510.]

💧 Seedling anatomy also reveals important taxonomic and ecological patterns. These include variation in water-storage tissue (hypodermis), stomatal position and the distribution of sclerenchyma around vascular bundles. (7/8)
Figure showing reconstruction of ancestral anatomical features. The evolutionary history of three leaf characteristics is shown: (Tree IV) the distribution of stomata (pores involved in gas exchange); (Tree V) the size of cells in the upper leaf surface (adaxial epidermis), viewed in cross-section; and (Tree VI) the presence or absence of an additional cell layer beneath the upper leaf surface (adaxial hypodermis).

🌎 By bringing together previously unsampled lineages and a broad range of seedling characters, this study provides a new framework for understanding the evolution of early development and vegetative adaptations in Bromeliaceae. (8/8)
